Abstract
Purpose – This paper aims to provide a comprehensive overview of the motives, structure and
performance attributes of horizontal cooperations between logistics service providers (LSPs). Based on
an analytical classification model, distinctive types of logistics cooperation that characterize the
logistics landscape are identified.
Design/methodology/approach – Empirical data were collected on horizontal LSP cooperations
from managers of German LSPs. Different uni- and multi-variate statistical methods including
ANOVA and cluster analysis were applied to the dataset of 226 cooperations for a total of 6,081
involved parties.
Findings – Horizontal cooperations with other LSPs are an organizational form used by 57 percent
of LSPs. Cooperation decisions are substantially driven by external market objectives. Six distinctive
types of cooperation are identified. They reveal the dominance of multi-lateral and international
networks that are mainly based on contractual agreements. There is a clear preference for partners with
similar market competencies and for strong functional integration. Despite its inherent complexity,
performance of these cooperations is high – its less than 19 percent failure rate makes these cooperations
substantially more stable than cooperations within manufacturing industries.
Research limitations/implications – This study is limited to an exploratory, descriptive
approach in providing a sound understanding of the cooperation landscape.
Practical implications – The findings contribute transparency to horizontal LSP cooperations and
a common understanding of their idiosyncrasies. The conclusions help logistics managers to position
themselves better within the cooperation landscape. Further, the analyses offer managers a conceptual
classification of horizontal LSP cooperations and some guidance on how to structure their individual
LSP cooperations more successfully.
Originality/value – This paper is the first empirical study that defines the types of cooperation that
comprise the logistics cooperation landscape. The analysis integrates a holistic perspective of their
contractual, organizational, functional, geographical, service and resource scope and matches them
with underlying motives and performance attributes.

1. Introduction
The rise of complex and global supply chains and the growing intensity of competition
continuously increase the challenges for logistics service providers (LSPs). A viable
way of reaction is to cooperate – either vertically with customers or horizontally

with other LSPs that are proximate or distant competitors. Over the last decade,
horizontal cooperation has vastly increased and become an important organizational
form for LSPs. The trade press can only provide a glimpse of this dynamic development,
when it reports that FedEx just established a partnership with an LSP from Israel to offer
expanded international freight forwarding services (The Wall Street Journal, 2010) that
APL Logistics announced a cooperation with an LSP from Japan to market global supply
chain services (Transportweekly, 2010), and that US Postal Service just entered into an
international agreement with an LSP from China to improve service quality for
American consumers ordering from merchants in China (Bloomberg, 2010). Our study
shows that today almost 60 percent of LSPs engage in at least one horizontal
partnership. Despite this fact, researchers and managers of LSPs have only limited
insights into the diverse patterns and opportunities of such cooperation.
While vertical cooperations between LSPs and shippers have already been covered by
an abundant body of literature that investigates, for instance, the typology of partners
and their relationships (Stefansson, 2006; Knemeyer et al., 2003; Lambert et al., 1996),
success factors of vertical logistics cooperations (Deepen et al., 2008; Lambert et al., 1999;
Moore, 1998; Tate, 1996), or attributes of partnership performance (Stank et al., 2003;
Gibson et al., 2002), research on horizontal cooperations between LSPs is still at an early
stage and hasmainly been limited to case studies that focus on specific modes of transport
(e.g. road: Lemoine and Dagnæs, 2003; Ludvigsen, 2000/rail: Ohnell and Woxenius, 2003;
Nijkamp, 1995/sea: Slack et al., 2002; Midoro and Pitto, 2000/air: Oum et al., 2004; Fan etal.,
2001; Glisson and Cunningham, 1996). As a notable exception, the latest work in this
research area by Cruijssen et al. provides an extensive literature review (Cruijssen et al.,
2007a) and first survey-based findings on opportunities and impediments for horizontal
cooperations in logistics (Cruijssen et al., 2007b).
Following Kale et al. (2000), there have been three research streams on strategic
cooperation management. The first investigates motives that drive cooperation
formation decisions; the second focuses on underlying governance structures; and the
third stresses the performance outcomes of cooperation activities. This paper extends
this body of knowledge on horizontal LSP cooperations in all three domains.
First, we analyze the motives of LSPs to establish a horizontal cooperation. Second,
we explore the structure of these cooperations. For this purpose, we develop a specific
framework based on the analytical model of Klint and Sjo
¨berg (2003). Our findings on
the cooperation structure allow us to identify distinct cooperation types that characterize
the logistics landscape. Third, we investigate cooperation outcomes based on
established performance measures provided by Pangarkar (2009), Schreiner et al.
(2009) and Saxton (1997). By doing so, we explicitly address the research gap outlined by
Cruijssen et al. (2007b, p. 36) who indicate the lack of “a general conceptual classification”
for horizontal LSP cooperations and advance knowledge on how cooperations are
structured and operated. These are important aspects of cooperation management that
still merit further empirical insights (Mayer and Teece, 2008).
The next sections begin with an overview of our research framework and the research
methodology. Subsequently, the empirical results are presented and discussed in order
to derive research and management implications and give directions for further research.

2. Conceptual framework
In this paper, we focus on horizontal cooperations between two or more LSPs who
strive for mutual benefits and positive relational rents (Dyer and Singh, 1998;
Lavie, 2006; Taylor, 2005). The parties jointly contribute resources in a certain area for a
potentially limited time, while preserving their strategic autonomy (Dussauge and
Garrette, 1997; Glaister and Buckley, 1996). This definition incorporates the dichotomy
of cooperation and competition (Bengtsson and Kock, 2000) and explicitly excludes
sub-contracting partnerships.
2.1 Cooperation motives
Firms establish horizontal cooperations for several reasons. These reasons depend on
individual resource endowments and industries (Glaister and Buckley, 1996; Tsang,
1998). For the logistics service industry, Cruijssen et al. (2007a) conducted in-depth
interviews and survey research to identify idiosyncratic cooperation opportunities.
They show that LSPs mainly associate productivity increase, service portfolio extension
and cost reduction with horizontal LSP cooperations. Further opportunities can arise
from better market positioning and improvements in service quality (Cruijssen et al.,
2007a). In addition, horizontal cooperations provide access to additional knowledge,
financial resources (Sakakibara, 1997; Deeds and Hill, 1996) or new markets (Glaister
and Buckley, 1996; Gulati and Singh, 1998).
2.2 Cooperation structure
Besides motives, the structural design of strategic cooperations has attracted
researchers’ interest for a long time. Starting in the early 1990s, scholars have
attempted to develop typologies and classify the extensive variety of cooperations.
Three prominent typologies with a rather narrow focus are the two-level typology of
Parkhe (1991), which builds on the similarity of resource endowments, the three-
category typology of Dussauge and Garrette (1997), which uses partnership-specific
attributes like geographic coverage and functional scope, and the 13-level typology of
Todeva and Knoke (2005), which is based on the cooperative governance structure.
Further, a comprehensive model was introduced by Klint and Sjo
¨berg (2003) for a more
holistic analysis. This model focuses on the eight most relevant factors for the structural
design of cooperations in general.
In order to derive an idiosyncratic framework for the analysis of horizontal LSP
cooperations, these eight factors were aggregated and translated into six distinctive
dimensions (Table I), each of which will be outlined by the following section:
(1) Our first dimension, “contractual scope”, refers to the factor “formality” of the
Klint and Sjo
¨berg (2003) model. While most studies of inter-firm cooperations
only distinguish equity-based and non-equity-based setups (Garcı
´a-Canal et al.,
2003; Dussauge and Garrette, 1997; Lunnan and Haugland, 2008), there is a
consensus that the full range from near arm’s-length agreements to joint venture
contracts is used in practice (Gulati and Singh, 1998; Todeva and Knoke,
2005). Within this range, four types of agreement can be distinguished: verbal
arrangements, written contracts without equity involvement, minority stake
agreements and joint venture agreements (Frankel et al., 1996; Teng and
Das, 2008).

(2) “Organizational scope” reflects the “number of companies” involved in the
cooperation. In this respect, a relevant distinction exists between bilateral
cooperations with two parties and multi-lateral ones with three or more
(Rubin de Celis and Lipinski, 2007). Several studies have demonstrated that
the organizational scope of a partnership has a strong impact on its effectiveness
(Griffith et al., 1998; Park and Russo, 1996). From a resource-based perspective, an
increased number of partners offer the opportunity to pool more resources and to
benefit from greater resource complementarity (Gong et al., 2007; Garcı
´a-Canal et al.,
2003). From a transaction cost perspective, however, more parties lead to higher
coordination and communication efforts (Gulati and Singh, 1998; Parkhe, 1993).
(3) “Functional scope”, a third dimension, reflects the factor “area of cooperation”
from Klint and Sjo
¨berg (2003) and specifies the functional focus of a cooperation
in terms of value creation. Following the concept of Porter (1985), value-creating
areas can be divided into primary and secondary activities. In providing value to
partnering companies, cooperations may address both primary and secondary
activities and may either be focused on one specific function or rather be broadly
organized by addressing several functions (Dussauge and Garrette, 1997).
Despite many analytical approaches to the functional scope of partnerships
(Hoang and Rothaermel, 2005; Anand and Khanna, 2000; Murray et al., 2005),
so far no empirical study exists that reveals the relative role of each functional
area in the overall value creation.
(4) “Service scope” and (5) “geographical scope” both reflect “product complexity”.
We transfer the notion of “product complexity” into two dimensions to capture
the complexity of logistics services:
.the type of logistics services offered; and
.the geographical coverage underlying these service offerings. Both
dimensions are undeniably interrelated – not only because services
are characterized by the simultaneity of production and use of the services

(Wagner, 2008), but also because LSPs belong to a network industry
where geographical presence is an important aspect of a firm’s competitive
edge (Oum et al., 2004). Therefore, both aspects induce the service
complexity that cooperating LSPs have to handle (Colombo, 2003;
Garcı
´a-Canal et al., 2003).
(6) “Resource scope”, the sixth and last dimension of our framework, integrates the
remaining structural factors of Klint and Sjo
¨berg (“complementarity”,
“importance of the region/district”, “company size”, and “social structure”),
all of which draw on the complementarity or similarity of resources that
determine the partnership setup. A first category of resource scope refers to the
“market competence (MC) profile” of cooperations by capturing overlapping
business activities and core competencies (Kale et al., 2000; Van de Ven and
Walker, 1984). The second category refers to the “market penetration (MP)
profile” of cooperations by capturing the degree of overlapping geographical
coverage and customer portfolios (Saxton, 1997; Oxley and Sampson, 2004;
Van de Ven and Walker, 1984). The third and last category of the
resource scope refers to the “corporate structure (CS) profile” and analyzes the
similarity of company size and social structure (Murray and Kotabe, 2005;
Kale et al., 2000).
2.3 Performance
Not all cooperations have lived up to their expectations. In many industries, the failure
rate of horizontal cooperations is alarming and ranges from 50 to 70 percent (Das and
Teng, 2000; Kogut, 1989; Park and Russo, 1996; Porter, 1987; Park and Ungson, 2001).
Therefore, it is not surprising that cooperation performance has gained much attention
from researchers (Saxton, 1997; Arin
˜o, 2003; Lunnan and Haugland, 2008).
In the search for a valid cooperation performance assessment, various measures – both
objective and subjective – have been developed. Arin
˜o (2003) classifies them as follows:
financial performance measures that either rely on accounting data (e.g. return on
investment: Luo, 2002) or on financial data (e.g. abnormal stock market gains: Anand and
Khanna, 2000), operational measures (e.g. cooperation membership duration: Harrigan,
1988), and subjective effectiveness measures based on perceptual performance evaluation.
Still today, there is no consensus on the optimal measurement of cooperation performance
(Das and Teng, 2003; Lunnan and Haugland, 2008).
3. Methodology
To identify characteristics and patterns of LSP cooperations, we applied an empirical
approach that consisted of both qualitative and quantitative elements. In a first
research phase, 12 in-depth interviews with logistics practitioners and researchers
were conducted to explore the general domain of horizontal LSP cooperations. Based
on these findings and extensive literature review, a survey instrument for large-scale
data collection was designed in the German language. To ensure reliability and
validity, we used – wherever possible – established constructs and measurement
scales stemming from the strategic management literature. With respect to face
validity, the final questionnaire was pre-tested with logistics researchers and nine
CEOs of LSPs who were asked to identify ambiguities in structure and wording.

3.1 Sample
For our sampling we used the Hoppenstedt database, which contains corporate
information on German firms with an annual turnover of more than e1 million. Based on
27 logistics-specific NACE codes (i.e. “Nomenclature Statistique des Activite
´s
E
´conomiques dans la Communaute
´Europe
´enne”) we identified 6,641 LSPs with legal
entities in Germany as potential respondents. Drawing on the key informant approach
(Kumar et al., 1993), managers at the executive level were targeted which were supposed
to be the most knowledgeable with respect to firm-specific cooperation activities. Valid
e-mail addresses for invitations to our online survey could be attained for 3,686 LSPs.
In order to increase the response rate, we followed the recommendation of Larson
and Poist (2004) and used incentives and reminder e-mails. Finally, we received
426 responses, providing a satisfactory response rate of 11.6 percent. Of these, 26 had to
be deleted because of missing data. The remaining 400 responses consisted of two
groups: 226 (56.5 percent) responses originate from LSPs that at that time belonged to at
least one horizontal LSP cooperation, while 174 responses originate from LSPs that did
not cooperate horizontally. Corresponding to our research aim, our analyses focus on the
226 cooperating LSPs. These 226 respondents were invited to select one horizontal
partnership as a reference point when answering our questions. Most respondents
(72 percent) referred their answers to the strategically most important one.
Descriptive statistics on our final dataset reveal that 53 percent of the respondents
were CEOs, 9 percent other members of the executive board and 36 percent held other
leading management positions. In addition, the statistics show that respondents have
an average professional experience within their company of more than 16 years which
indicates their familiarity with firm-specific strategies and processes. Additional
descriptive statistics are presented in Table II.
We used a variety of methods to test for potential non-response bias. It was assessed
by comparing:
.early and late respondents with respect to survey variables (Armstrong and
Overton, 1977); and
.respondents and non-respondents with respect to available company
demographics from the company database.
Further, we conducted a follow-up study with 250 randomly selected companies from
the initial sample for investigating cooperation propensity and company demographics
and compared these responses to those of our 226 respondents. Neither method
indicated significant differences between sampled and target population.
3.2 Measurement
3.2.1 Cooperation motivation. To identify the main motives behind the formation of
horizontal cooperations, respondents were presented a list of motives and asked to
indicate on a seven-point scale the importance of each of them for making the
cooperation decision. The list included six cooperation opportunities suggested by
Cruijssen et al. (2007a) and was complemented by three additional motives often
discussed in literature: access to financial resources, access to new markets (Deeds and
Hill, 1996; Glaister and Buckley, 1996; Gulati and Singh, 1998) and access to additional
knowledge (Sakakibara, 1997).

3.2.2 Cooperation structure. The architecture of the cooperation landscape was examined
via the six dimensions of our cooperation structure framework. To capture “contractual
scope”, we used a categorical variable that distinguishes four types of contract
(Frankel et al., 1996; Teng and Das, 2008; Reuer and Arin
˜o, 2007): verbal agreements,
contractual agreements that involve no equity stakes, minority equity agreements and
joint venture agreements. “Organizational scope” was measured through the total number
of LSPs involved in the cooperation (Gong et al., 2007; Colombo, 2003). “Functional scope”
was operationalized by asking the respondents to distribute a total of 100 points to a list of
seven functional areas according to the importance each functional area accounts for
value creation. The functions were selected following Porter and Fuller (1986) and
comprise production, marketing and sales, procurement, human resources, research and
product development, IT and administration and finance and accounting. “Geographical
scope” was measured via a categorical variable which distinguishes a national scope,
subsuming regional and nationwide reach, and an international scope, subsuming
continental and intercontinental reach (Glaister and Buckley, 1996). For the “service
scope” we used a categorical variable that denotes the mode of transport (road, rail, sea, air
and intermodal transport as well value-added services) with which the cooperation
generates most revenue. “Resource scope” describes the extent to which the cooperating
parties contribute either complementary or similar resources in terms of type and amount
(Das and Teng, 2003). Respondents were asked to indicate the degree of resource overlap
characterizing their partnership concerning business activities and core competencies
(MC), geographical network and customer portfolio (MP), financial strength, managerial
strength, management style and corporate culture (CS). All eight resource items were

measured on a seven-point scale, ranging from full complementarity (1) to full similarity
(7). Since MC, MP and CS represent indices of items that were drawn from the Klint and
Sjo
¨berg model and from extensive literature review (Van de Ven and Walker, 1984; Oxley
and Sampson, 2004; Kale et al., 2000; Murray and Kotabe, 2005; Mitsuhashi and Greve,
2009), they were calculated as average scores of the corresponding items.
3.3 Cooperation performance
To provide a valid overview of cooperation performance, we followed the approach of
Lunnan and Haugland (2008) and relied on a combination of established scales. We
employed the failure rate to assess performance at the industry level and used
relationship duration and cooperation effectiveness to assess performance at the
individual cooperation level.
“Failure rate” serves as an overall measure of performance. In order to calculate a
reliable failure rate, we first identified the total number of horizontal cooperations each
respondent had already terminated due to failure. We explicitly excluded past
cooperations that were terminated for other reasons like goal achievement. Second, we
identified the total number of cooperations in which each respondent was engaged
when the survey was conducted, and calculated the failure rate by dividing the number
of failed cooperations by the sum of cooperations that were still running and those that
failed. This measurement approach follows Pangarkar (2009) and Park and Russo
(1996). It assumes that experience with cooperation failure can be counted and set in
relation to the overall cooperation experience. Since we neglected past cooperations
that had been terminated for other reasons than failure, our measurement presents an
upper bound of the industry-specific failure rate[1].
“Relationship duration” is regarded a reasonable proxy for cooperation success and
stability (Pangarkar, 2003; Harrigan, 1988). To capture relationship duration, we followed
Schreiner et al. (2009) and employed a single item asking for the number of consecutive
years the company had been maintaining the cooperation.
Given the fact that executive managers establish inter-firm partnerships for specific
reasons, their individual perception of “cooperation effectiveness” has shown to be an
accurate means to evaluate cooperation performance (Kale et al., 2002; Lin and Germain,
1998; Geringer and Herbert, 1991). For its measurement we used the well-established
performance scale of Saxton (1997). It captures whether the partnership has achieved its
primary goals, whether it has given a boost to the competitive advantage and core
competencies of the parent firm, and whether the parent firm is satisfied with the
cooperation’s overall performance.
4. Empirical results
4.1 Cooperation motives
The empirical data show that the three most important motives for cooperation formation
(displayed in Table III and assessed via mean scores on a seven-point scale) are the
opportunity to improve service quality (5.86), the opportunity to accrue positive market
share benefits (5.78) and – with a significant decline – the opportunity to specialize while
extending service offerings (5.20). Motives that are related to increased productivity of core
activities only rank fourth place (5.07), to reduce costs of non-core activities only eighth place
(3.14) and to gain access to financial resourcesevententhplace(2.15).Thisshowsthatin
general external, market-oriented motives outweigh internal, cost-oriented motives.

However, with increasing strategic importance of cooperations the productivity motive
gains in relevance. In the group of strategically most important cooperations, this
motive obtains the third rank with a mean score of 5.23, while it only ranks fifth at 4.67
in the group of other cooperations. The latter group of cooperations instead put more
emphasis on broadening their service profile (third rank at 5.39) and on gaining access
to new markets (fourth rank at 4.91).
Our results contribute new insights to cooperation motives and thus extend the
findings of Cruijssen et al. (2007a), who assessed the opportunities with which LSPs
associate horizontal partnerships. They found that significant cost reductions and
productivity increases are seen as the most important opportunities. In comparison, we
investigated the motivational factors driving the actual cooperation decision and found
that service quality improvement and market share enhancement are the most
important decision-driving motives. Thus, we assert that when it comes to actual
decision making, the relevance of cost-oriented motives decreases, while that of
market-oriented motives increases.
4.2 Cooperation structure
Referring to the “contractual scope”, our results reveal that horizontal LSP cooperations
are predominantly based on written agreements. Of the cases, 49 percent use contractual
agreements, 32 percent of the cases employ written contracts with minority stakes and
6 percent joint ventures agreements. Only the remaining 13 percent of cooperations use
verbal agreements.
In the context of strategic cooperations, equity involvement serves as a valuable
mechanism to control for opportunism and align partners’ interests (Gulati and Singh,
1998). Although equity involvement is not the most prevalent governance mechanism

for horizontal LSP cooperations, its relevance significantly grows with increased strategic
importance ( p,0.05). Of the strategically most important cooperations, 43 percent are
based on equity stakes, while the share is only 25 percent for other cooperations.
In terms of organizational scope, 31 percent of the cooperations are bilateral, while
69 percent are multi-lateral and span a wide range of constellations: 28 percent of the
cooperations involve three to ten LSPs, 24 percent involve 11-50 LSPs, 12 percent
include 51-100 LSPs and 5 percent consist of more than 100 independent LSPs. On
average logistics, cooperations involve 27.0 LSPs with a median of five[2]. These
numbers are substantially higher than in other industries (Friese, 1998). For example,
Park and Russo (1996) and Gong et al. (2007) identify joint ventures of manufacturing
companies to have on average 2.3 parent companies in the USA and 2.4 in China, while
the corresponding figure in our study is 10.5. Further, Li et al. (2010) analyzed
secondary data on marketing cooperations in 48 industries across 164 countries
between 1992 and 2008 and found that most cooperations only involved two parties,
while marketing and sales cooperations in our study include a minimum number of
five parties and an average of 25.2 parties.
Based on the findings of Cruijssen et al. (2007a), we expected the “functional scope” of
logistics cooperations to focus on primary activities – in particular service production.
This was confirmed by our empirical results. On average, 39.9 percent of the
cooperation’s value creation is contributed by production, 25.4 percent by marketing and
sales. Concerning the secondary activities, procurement attributes most with
13.1 percent, while the other functions contribute the remaining 21.6 percent: IT and
administration account for 6.6 percent, human resources for 6.2 percent, research and
development for 5.6 percent and finance and accounting for 3.2 percent.
To deepen the understanding and possibly identify patterns of functional scope,
we also conducted an agglomerative hierarchical cluster analysis. Based on the
average linkage algorithm with squared Euclidean distance, four functional clusters
were identified. Three of them have an idiosyncratic functional focus, while one
exhibits broad functional integration. Table IV shows the average value creation by
function for each cluster identified:
.Functional Cluster 1 has a production focus where, on average, the production
function contributes 70 percent of the cooperation’s value creation. This functional
cluster is common, representing 88 of the 226 cooperations (39 percent).

.Functional Cluster 2 is focused on marketing and sales activities. These functions
account for 74 percent of the cooperation’s value creation. Of cooperations,
11 percent belong to this cluster.
.Functional Cluster 3 has a procurement focus. Here on average, 81 percent of the
cooperation’s value creation is attributed to procurement. This cluster is rare and
represents only 5 percent of the cooperations.
.Functional Cluster 4 is characterized by broad functional integration. Marketing
and sales (30 percent), production (24 percent) and procurement (16 percent) are
the main value-creating areas. Still, the remaining functions contribute over
30 percent of the cooperation’s value in nearly equal parts. This cluster is most
common and comprises 45 percent of all horizontal LSP cooperations.
Our findings relate to the typology presented by Dussauge and Garrette (1997) who
distinguish between cooperations of “shared marketing and sales” (corresponds to
Functional Cluster 2), “shared supply” (corresponds to Functional Cluster 3) and
“quasi-concentration” (corresponds to Functional Cluster 4). In comparison to their
classification, the logistics service industry exhibits one additional cooperation type,
which is “shared production” (Functional Cluster 1).
It is interesting to note that the most prevalent cooperation type (Functional
Cluster 4 – quasi-concentration) involves multiple important functions and
consequently has to build on high levels of functional integration. The more functions
are involved, the more processes have to be integrated and aligned, and the more
resources of a focal partner are affected by the partnership. Thus, we propose that broad
functional integration adds a substantial level of complexity to LSP cooperations that
requires special coordination efforts.
With regards to the “geographical scope”, our results show that 33 percent of
logistics cooperations operate nationally, with either a regional (9 percent) or a
nationwide reach (24 percent), while the majority (67 percent) of cooperations has an
international scope, with either continental (53 percent) or intercontinental (14 percent)
coverage. Geographic coverage seems to be an important aspect of sustainable
competitiveness for horizontal LSP cooperations regardless of strategic relevance.
Results concerning “service scope” point out that the majority of cooperations
(69 percent) are active in the road-based service segment, while only 4 percent focus on
air freight, 7 percent on rail freight, 4 percent on water transport and 12 percent on
intermodal logistics services. The remaining 5 percent jointly offer value-added
services. The dominance of the road-based segment is not surprising due to the large
number of truckload firms that shape the logistics industry.
Our findings provide further evidence that the “resource scope” of cooperating LSPs
is not per se symmetrical or complementary. Cooperations, rather, build on a viable
resource similarity-complementarity mix. Mean scores of the resource indices indicate
that horizontal LSP partnerships are characterized by rather similar MC profiles (4.46),
rather complementary MP profiles (3.25) and highly complementary CS profiles (2.81).
Interestingly, the strategically most important cooperations build on even more
similar MC profiles (4.70) and even more complementary MP profiles (3.17) than other
cooperations ( p,0.05 for both resource indices). These findings emphasize the
strategic importance of overlapping business competencies in horizontal LSP
cooperations.

Since horizontal partnerships must cope with the phenomenon of coopetition, direct
competition is best avoided by some degree of complementarity (Bengtsson and Kock,
2000). Further analyses show that those LSP partnerships with highly similar MC
profiles (MC index .5.0; n¼93) unify partners with highly complementary MP
profiles (3.12). In contrast, those with highly similar MP profiles (MP index .5.0;
n¼25) unify partners with complementary MC profiles (3.68).
In order to provide an aggregated overview of the cooperation architecture,
Figure 1 shows the prevailing characteristics along all six dimensions of our structural
framework. The dark-shaded areas refer to the most dominant characteristics, while
the light-shaded areas refer to the second most dominant characteristics.
4.3 Performance
This study indicates that horizontal LSP cooperations are rather stable and successful
partnerships. More than 50 percent of respondents have had no experience with any kind
of cooperation failure. In addition, the upper bound for the industry-specific failure rate is a
low 18.9 percent. This can be inferred from the fact that our respondents were engaged in
1,602 horizontal LSP cooperations when the survey was conducted (i.e. an average
of 7.1 cooperations per LSP), while having experienced 373 failed partnerships
(i.e. 1.7 cooperation failures per LSP). We used our follow-up study with 250 randomly
selected LSPs for validation. Since this study reported an even lower failure ratio (just
14.7 percent), our assumption is supported that the initial result of 18.9 percent represents
an upper bound. The true value can be expected to be even lower – probably around
15 percent. Comparing these failure rates to those reported for manufacturing industries
that range from 50 to 70 percent (Park and Ungson, 2001; Bleeke and Ernst, 1991),
cooperations in the logistics industry can be assessed as both stable and successful.
In line with these findings, our study shows that most horizontal LSP cooperations
are long term with an average cooperation duration of 7.6 years and with 15 percent of
LSPs that were participating for 15 years or more. In addition, the average cooperation
effectiveness is high with a score of 5.45 on a seven-point scale and with a standard
deviation of 1.08. This latter aspect reflects that very few cooperations exhibit truly
poor performance.

4.4 Cooperation types
Following previous research (Dussauge and Garrette, 1997), we used cluster analysis to
identify distinctive cooperation types based on their structural characteristics. For this
purpose, we translated the structural dimensions into categorical variables and integrated
them as binary data into hierarchical cluster analysis. Based on the agglomerative
algorithm of average linkage and the squared Euclidean distance, results suggested that
a six-cluster solution best suits thedata.TableV showsthe major characteristics of the six
types of cooperation, and Figure 2 shows a graphical representation.
Cooperation Type 1: dense road-based networks with shared production focus.
Cooperation Type 1 (n¼67; 30 percent) provides road-based transport services in large
international route networks. For this purpose, Type 1 cooperations integrate up to
130 members that share highly complementary MP profiles. The aim is to improve
service quality and protect market share, while also increasing productivity of core
activities. As a consequence, cooperation partners have highly similar MC profiles
which facilitate the realization of economies of scale. Given the high degree of
competence similarity and a high strategic importance characterizing Type 1
cooperations, it is not surprising that agreements with equity involvement are the
preferred type of contract. This helps to avoid opportunistic interest seeking, fosters
stability (Teng and Das, 2008), and leads to an average duration of 12.1 years and an
above average cooperation effectiveness score of 5.59[3].
Cooperation Type 2: customized road transport networks with broad functional
integration. Cooperation Type 2 (n¼104; 46 percent) can be considered as a counterpart
to Type 1 since it is characterized by comparable service concepts, resource profiles and
organizational structures. It also focuses on road transport services – but to a lesser
extent – integrates partners with similar MC profiles and tries to establish international
route networks by involving multiple partners. However, the median number of parties
is just five and, thus, considerably smaller than with Type 1. Further, Cooperation Type
2 is distinguished by a certain degree of customization and by a higher degree of
functional integration that provides idiosyncratic market strengths. While some of the
Type 2 cooperations try to differentiate by providing intermodal services in combining
road transport with other modes of transport (e.g. rail and sea freight), others limit their
geographical focus to smaller areas. The idiosyncratic combination of structural factors
results in average performance with a cooperation effectiveness score of 5.38 and a
relationship duration of 6.0 years.
Cooperation Type 3: situational road transport networks with shared production
focus. Cooperation Type 3 (n¼21; 9 percent) is also specialized in road-based transport,
but with a distinctive focus on shared production. In comparison to the first two clusters,
Cooperation Type 3 differs by including a small number of parties and by a stronger
national focus. Further, this partnership type relies only on verbal agreements, where
trust and integrity replace formal authorities (Frankel et al., 1996). We assume that trust
and integrity are grounded on personal relationships that probably evolved more easily
since LSPs of this type not only have similar market competencies, and similar MP
capabilities, but even have similar company cultures (4.33). The similarity between
company cultures is intended to serve as a necessary foundation for cooperations that
are based on verbal arrangements.
Our initial expert interviews indicate that this cooperation type follows situational
business patterns. They are, for instance, activated when one partner is facing demand

fluctuations and needs additional haulage or warehouse capacity. Consequently,
Cooperation Type 3 resembles neighborly help activities and is, thus, assumed to be
the oldest form of horizontal partnering between LSPs. The occasional nature of these
cooperations explains their somewhat limited overall performance impact and the
lowest effectiveness scores of all six types (5.05 compared to an average of 5.49 for all
other cooperation types).
Cooperation Type 4: sea and air freight cooperations with marketing and sales focus.
In contrast to the first three cooperation types, the fourth one (n¼11; 5 percent) is made
up of sea and air freight carriers. They established bilateral partnerships with an
international market coverage to promote products and services. In contrast to joint
production networks, shared marketing and sales networks can reduce interdependencies
and coordination efforts. This might explain why Type 4 cooperations rely on the use of
non-equity agreements.
If partners decide to market products and services, these offerings should be
compatible and comply with identical quality standards. This requires some partner
similarity. Type 4 partnerships are characterized by a significantly higher ( p,0.05)
similarity of management style (4.60), financial strength (3.70) and customers portfolio
(5.09) than other cooperation types, where the corresponding values are only 3.33, 2.31
and 3.59. Therefore, we assume that the similarity of these resources allows the
establishment of a common understanding about service quality and thus helps to
promote products and services on behalf of the other partner. Based on this structural
set up, Type 4 cooperations exhibit high cooperation effectiveness (5.58).
Cooperation Type 5: national value-added service cooperations with broad functional
integration. In contrast to most of the other cooperation types, Type 5 (n¼11; 5 percent)
does not focus on traditional freight business. Instead, it is specialized in value-added,
non-transport services like packaging, warehousing, contract logistics or reverse logistics
and determined by a broad functional integration across service production, marketing

and sales and procurement. Further, this cooperation type is the only one with a very
strong national focus. Based on these aspects, it can be inferred that transport-oriented
cooperations utilize international networks to enhance competitiveness, while
non-transport-oriented cooperations profit less from internationalizing.
Moreover, Type 5 partnerships are unique in that they are driven by the intention to
gain additional knowledge and extend service offerings, while access to additional
markets (4.09) or increase of profitability in core activities (3.55) are only of minor
importance. In line with the motivation to foster knowledge exchange – mainly on a
bilateral level – Type 5 cooperations are formed between highly complementary
partners, with low resource similarity in all three resource categories (MC ¼3.68,
MP ¼3.73, CS ¼2.68). To cope with both, resource complementarity and functional
quasi-concentration, these cooperations mostly employ equity-based contracts. This
helps to align diversified cooperation incentives of heterogeneous partners and
counteract exchange hazards. We suppose Type 5 to be at an early stage of
development since the average duration is just 3.5 years. This might also explain why
the cooperation effectiveness score is below average (5.21).
Cooperation Type 6: bilateral hinterland cooperations with shared production focus.
Cooperations of type 6 (n¼12; 5 percent) represent hinterland logistics partnerships
that focus on shared production and often are confined to very specific regions. They
specialize in rail transport that is combined with value-added services like warehousing,
terminal operations and customs clearance or with other modes of transport. Since rail
logistics require a considerable amount of assets, the LSPs involved tend to be rather
large. Companies that are active in these partnerships focus on core competencies and
complement them by establishing bilateral cooperations, especially with LSPs that can
contribute complementary MC profiles (3.17). Owing to the focus on a particular
hinterland region, it is not surprising that these cooperations, more so than others, have
highly similar MP profiles (4.25). This allows them to offer the full range of services
required for efficient hinterland logistics. For governance, they employ
contractual agreements. From a performance standpoint, they can be considered as
very successful – not only because of the highest average effectiveness score (6.06)
of all clusters, but also because of their very narrow performance spread (SD ¼0.47).
5. Conclusion
Given the market relevance of horizontal LSP cooperations, a thorough understanding
of their major characteristics and of the cooperation landscape is crucial. In this regard,
our paper contributes the first comprehensive overview of cooperation motives,
structures and performance outcomes while capturing the full diversity of the logistics
service industry. Our analysis thus extends previous work that was more focused on
individual elements and facets of the picture.
Academic implications
Our study is the first to provide an explicit ranking of motives for LSPs to engage in
horizontal cooperations. This not only helps to understand the dynamics that shape the
industry. It also shows that opportunities generally associated with these cooperations
(as identified by Cruijssen et al., 2007a) differ from the motives for the actual decision.
Empirical evidence is found that cooperation decisions are primarily driven by an
external market perspective rather than an internal productivity and cost perspective.

In fact, a special focus is on the improvement of service quality and market share
protection which is consistent with the fact that in mature industries it is very often
service quality and not costs that “makes the difference” between market participants
(Bell et al., 2005).
Based on an analytical framework derived from Klint and Sjo
¨berg (2003), this study
systematically captured the full range of structural characteristics that determines the
architecture of LSP cooperations. Consistent with the structure-conduct-performance
paradigm (Klint and Sjo
¨berg, 2003), each of these structural dimensions shapes cooperative
behavior and the partnership outcome. Thus, a profound understanding of the cooperation
structure adds substance to the interpretations of cooperation performance. With respect to
the functional focus of the cooperations, we were able to confirm the three basic functional
patterns identified by Dussauge and Garrette (1997) and extend their classification by
adding shared production as a fourth functional pattern. Overall, we identified six distinct
cooperation types that describe today’s logistics cooperation landscape.
Further, our study contributes new insights to the discussion of cooperation success.
Many researchers (Park and Ungson, 2001; Kale et al., 2002; Hoang and Rothaermel,
2005) refer to cooperation failure rates of 50-70 percent that initially have been reported
by scholars like Porter (1987), Kogut (1989) or Bleeke and Ernst (1991). In contrast to
these results, we found that horizontal LSP cooperations are substantially more stable.
Their failure rate is well below 19 percent, along with an average partnership duration of
eight years and high scores in performance effectiveness. These findings highlight that
success rates can vary enormously between industries and that industry-specific
success evaluations are more appropriate than industry-independent ones.
Managerial implications
The cooperation landscape that has been derived from our empirical results
contributes transparency and a common understanding of market characteristics.
This transparency will help logistics managers to position themselves better within the
cooperation landscape. It also facilitates the identification and development of
innovative cooperation concepts which in turn can foster differentiation from industry
peers. In this respect, our work responds to the call by Cruijssen et al. (2007b) to develop a
conceptual framework that allows the classification of horizontal LSP cooperations and
supports practitioners in setting up such partnerships.
Moreover, the transparency on the facets of structural complexities – for instance
driven by the very large number of partners or by the broad geographical scope –
helps to direct management attention to the setup of appropriate governance structures
and management capabilities. In order to keep cooperation structures manageable over
the lifecycle of the partnership, logistics managers are recommended to pay special
attention to the structural aspects outlined. In particular, the high complexity driven by
strong functional integrations and complementary resource setups requires logistics
managers to strike the right balance between the independence of their individual
company and the interdependence within the cooperation.
Although many LSPs already cooperate, our initial expert interviews confirmed that
a common understanding about the scope and market potential of horizontal LSP
cooperations is still missing and that misconceptions about its actual predominance
prevail. Therefore, our study helps to establish more profound cooperation knowledge.
Our findings show that horizontal cooperations are not only used for highly
Horizontal

Downloaded by Technische Universität Berlin At 09:07 25 October 2017 (PT)
standardized services like road-based transport, but also for more complex or
individualized services (e.g. intermodal transport, contract logistics and value-added
service offerings). Further, our results bring to attention that production cooperations
with joint operations in interlinked physical networks do not dominate the landscape. In
fact, cooperations with highly integrated functions along the continuum of primary and
secondary functions play an even bigger role, while cooperations in the fields of
marketing and sales and procurement should not be neglected.
Finally, the study outlines a substantial potential for future partnerships referring to
the number of LSPs that are still preserving an independent market position (43 percent)
or that are just involved in one partnership (18 percent). Since our findings reveal that
LSP cooperations are highly stable and successful, these industry participants might be
encouraged to be more receptive to this organizational form. Others are already very
confident about horizontal partnerships. This can be inferred from the fact that only
3.1 percent of the LSPs interviewed in the follow-up study of 250 LSPs indicated that
they plan to reduce their cooperation activities, while 27.6 percent expect to expand
them, recognizing globalization as a major driver. We, therefore, conclude that
globalizing fortifies the relevance of external, customer-oriented market motives within
the logistics industry and that LSPs continue using horizontal partnerships to
strengthen competitiveness and resist market consolidation tendencies.
Limitations and further research
This research is marked by certain limitations. First, we have focused on cooperations
that were running when we conducted our study and excluded those that had already
been terminated. However, in our view, it would be valuable to extend the scope of
analysis by also investigating terminated horizontal LSP cooperations. In particular,
investigations of key characteristics that distinguish cooperations that failed from
those that had been terminated for other reasons in addition to investigations of key
antecedents for cooperation failure would be quite valuable.
Second, our results only refer to LSPs with legal entities in Germany. Although
Germany is Europe’s largest economy, we recommend that future work extend the
scope of research to other regions and analyze whether or not cooperation motives,
architectural structure and performance attributes differ by geographical setting.
Despite these limitations, our analyses provide some important insights to
horizontal LSP cooperations. We consider our work as part of an emerging research
stream that will refine our understanding of these highly relevant partnerships. In this
respect, it would be worthwhile to complement this explorative study as a basis for the
analysis of causal relationships. We encourage future studies to examine the question
how the complexity dimensions that have been outlined by our study affect
cooperation governance, management capabilities and thus cooperation performance.
The complexity dimensions will most likely also impact the effectiveness of crucial
partnership characteristics like communication behaviour and conflict resolution
techniques that Mohr and Spekman (1994) have investigated. Including these aspects
in future studies will be of great value.
Notes
1. The actual failure rate is the number of failed cooperations dived by the sum of cooperations
still running, cooperations failed, and cooperations terminated for other reasons.

2. The largest numbers of partners are typical for international cooperations in the “less than
truck load” segment, where many LSPs are required to provide full coverage of large
geographic areas.
3. Failure rates were calculated with relations to LSPs. As each LSP on average is engaged in
seven cooperations it is most likely that not all of them are of the same type. Therefore,
no failure rate can be concluded for specific cooperation types.
