Research on the Impact of Supply Chain Integration of Startups : Service Supply Chain Perspective

As the potential power of social economic development, the importance of startups has attracted more and more attention from academia. The service supply chain, led by the service integrator, can help the startups to improve the performance of the enterprise, achieve better supply chain integration, and go through their “infancy” period successfully. However, the research about the factors that influence the integration of service supply chain and how these factors affect the supply chain integration of startups remains to be explored. Based on the practical problems and theoretical research status above, this study constructs a theoretical hypothesis model of the relationship between interaction, supply chain finance and supply chain integration, and we take the survey data of 65 startups in Pearl River Delta of China as samples and use hierarchical regression analysis to carry out hypothesis testing. The result shows that, from the perspective of startups, interaction has a positive impact on supplier integration, internal integration and customer integration, and supply chain finance has a positive impact on internal integration. The main significance of this study is to make up for the vacancy on this part of the academic community in the service supply chain, and help provide some reference basis for start-up enterprises’ supply chain integration.


Introduction
With the transformation and upgrading of the world economic structure, the old mode of production is now seeking new breakthroughs.For the traditional enterprises emerge as the times require and open up a new market.The supply chain service enterprises integrate various resources and build up a platform, where service request of startups (customers) are decomposed and outsourced to appropriate service providers (suppliers) on the platform.In that progress, the supply chain service enterprises are responsible for customer demand decomposition, service factor matching, information transfer, partnership maintenance and so on.Thanks to that, startups can focus on their core business.
Startups are not only a new power to stimulate national economic growth, but also an important force to stimulate domestic demand and create jobs.Therefore, how to help startups grow better is an issue of particular concern to all sectors of society.Considering the difficulties encountered in the early development of startups, this paper discusses the impact of supply chain finance and interaction on the supply chain integration of startups from the perspective of service supply chain.The main significance of this study is to make up for the vacancy on this part of the academic community in the service supply chain, and help provide some reference basis for start-up enterprises' supply chain integration.

Supply Chain Integration
Increasing the level of supply chain integration among supply chain members has become a necessity for the improving of the performance of the supply chain H. Lin, Q. Lin DOI: 10.4236/jss.2018.64022257 Open Journal of Social Sciences system.Despite the abundant research on unidimensional supply chain relationships, the SCI construct is a relatively new as an area of research [2].Supply chain integration is defined as "the degree to which a firm can strategically collaborate with its supply chain partners and collaboratively manage the intra-and inter-organization processes to achieve effective and efficient flows of product and services, information, money and decisions with the objective of providing maximum value to customers at low cost and high speed" [2].Vickery et al. state that the challenge of supply chain integration is the managerial capacity for combining resources and competencies from various supply chain members and business units, and directing all relevant parties towards an expanded resource base and competitive advantage [3], which means that it should be strategically managed as an integrated system as opposed to individually optimized fragmented subsystems.Maloni and Benton report that in order to provide customers with greater value and gain competitive advantage, a higher level of cooperation is required for supply chain partners, which leads to integration of the supply chain [4].Some researchers characterize integration as interaction, in which communication in form of and information flows and meetings are employed to unite firms on supply chains [5] [6] [7].Another type of researches characterize integration as collaboration, where firms on a supply chain or departments within a firm work collectively under common objectives [8] [9].Others put forth a composite view which characterize integration as information sharing and involvement [10] [11], while empirical work by these researches fail to delineate clearly between information sharing and involvement.This study build upon previous research on the SCI construct, arguing that the diverse dimensions of SCI being collapsed into three dimensions, supplier integration, internal integration and customer integration.In which supplier and customer integration are commonly referred to as external integration.

Resource-Based Theory
In 1984, Wernerfelt put forward "The Resource-Based Theory of the Firm", and it symbolized the formal generation of the resource-based theory [12].After that, the theory has been continually supplemented and improved by Barney Peterafand many other scholars through theoretical and empirical research [13] [14].Nowadays, the resourced-based theory can be roughly divided into three schools---traditional resource theory, enterprise competence theory and enterprise knowledge-based theory.1) The traditional resource theory, represented by Wernerfelt's "The Resource-Based Theory of the Firm", believes that an enterprise is a unique collection of all resources.In order to stand out in the competition, enterprises must acquire the valuable, scarce, heterogeneous, inimitable and irreplaceable resources.The focus of supply chain integration is to integrate the decisive resources with the features above, especially the internal resources that are difficult to obtain from external transactions.2) The enterprise competence theory defines the enterprise competence as the capability to allocate re-sources reasonably and efficiently [15], which is crucial to gain competitive advantage.What's more, most scholars consider that the allocation of resources is a dynamic process.Only when the enterprise can adjust, configure and integrate the internal and external resources according to the change of the market environment can it occupy the favorable position of the market.3) The knowledge-based theory considers that enterprise is the aggregation of knowledge which is summed up during the long-term practice and operation.Hence, enterprise needs to maintain long-term and continuous learning to expand the field of knowledge and keep competitive advantage.
In the field of supply chain management, the application of the resourcebased theory emphasizes the integration and utilization of the internal and external resources of the enterprise.For startups, capital is one of the scarcest resources for survival and development.Accordingly, supply chain finance, as an effective way for startups to obtain funds, becomes an important direction to study supply chain integration.Meanwhile, interactions can help startups to establish and strengthen social relations and partnership, and get better external resources that they themselves cannot access.Therefore, from the perspective of resource-based theory, this paper discusses the impact of supply chain finance and interaction on achieving higher levels of supply chain integration in startups.

Transaction Cost Theory
The Transaction Cost Theory was proposed by Ronald Coase in 1937 when he put forward the famous Coase Theorem.According to the theory, enterprises acquire external resources in the process of market trading, but at the same time, it also produce transaction costs which may have negative impact on enterprise performance.Hence, rational allocation of resources is the key to reduce transaction costs.Williamson enriched the transaction cost theory on the basis of Coase's research and proposed that asset specificity, transaction uncertainty and transaction frequency were three characteristics in the business process [16].Besides, he concluded six factors that that could affect the transaction cost of an enterprise: opportunism behavior, bounded rationality, uncertainty, small numbers, information asymmetry and atmosphere.After that, the transaction cost theory has been widely used in social science reseach, including supply chain integration.In fact,the transaction cost theory can explain the formation mechanism of supply chain integration well.For example, Frohlich et al. and Flynn et al.
suggest that enterprises that adopt the supply chain integration strategy will invest in specific assets according to their business needs [17] [18].If an enterprise makes a separate investment in a specific asset, once the business needs to be replaced by the change in the market, that enterprise may have to take an expensive cost.Conversely, if supply chain partners can take a joint investment based on certain agreement, there will be a chance to reduce the risk.
The essence of supply chain is that enterprises can work synergetically to reduce overall transaction cost through the establishment of great partnerships.
Interaction, as the essential feature of the service supply chain, can help promote the establishment, consolidation and expansion of relationships.Based on the analysis above, this paper will study the relationship between interaction and supply chain integration on the basis of transaction cost theory in startups.

Literature Review and Hypothesis Development
At present, the definition of service supply chain in the academic circles can be divided into three categories.The first one considers the service supply chain as the service-related links in the supply chain, and the second one describes the service supply chain as the supply chain of the service industry or the service sector.Based on the limitations of the two definitions above, this paper agrees with the third definition that defines the service supply chain as an integrated supply chain which is service oriented [19].In this supply chain, the supply chain service enterprise occupies a leading position.once the downstream customer makes a service request, the service integrator will respond immediately, and then decompose and assign it to service providers at different service positions to meet requirements step by step.through this process, service providers cooperate with each other and constitute a supply relationship, and the integration and management of various elements in the whole supply chain is undertaken by the service integrator.Hence, in summary, the service supply chain discussed in this study refers to the third type of definition above, which is a supply chain oriented by the integration of resources and service.Besides, scholars have divided the supply chain integration into several dimensions from different angles and structures [2] [5] [6].Based on previous research, this paper divides the supply chain integration into supplier integration, customer integration and internal integration.

Relationship between Interaction and Supply Chain Integration
Interaction is a typical feature of the service supply chain and it emphasizes the active and conscious mutual influence among the supply chain members.The concept of interaction is different from information exchange and communication.Information exchange is the basis of interaction and communication, while communication means that two parties negotiate and fulfill their commitments in an agreed framework.By contrast, interaction is a process of mutual learning and value co-creation under non-constraint conditions.Hakansson proposed the basic framework of the interactive model, describing interaction using interactive process, interactive subject, environment and atmosphere [20].In service supply chain, the elements of interaction include all kinds of internal and external resources, such as products, information, funds, service brands and so on.
Based on our research objects, this paper discusses the interaction between the startups and the service integrator.
With the rise of service outsourcing, the interaction has become a key link to improve performance of the service supply chain members.Edvardsson and Open Journal of Social Sciences Cova believe that the enterprise connections in the service supply chain is no longer a simple supply-demand relationship in upstream and downstream, but an interdependent relationship, which is resulted from the joint action of both parties [21].Therefore, the interaction in the service supply chain can promote the overall integration of supply chain.Song Hua considers that in current economic context, customer consumption is more and more personalized [19].The interaction between supply and demand can help deepen the understanding of customer requests, while technological advances make that process much more efficient.More importantly, through supply chain interaction, enterprises can effectively explore partners' resources and capabilities, so as to better cooperate with other supply chain members in terms of strategy, operation and process.At the same time, startups are mostly technology-oriented enterprises who adopt differentiation strategy, and for them interaction can make the capability and effectiveness of resource integration substantially enhanced.Yu et al. propose that interaction is a typical feature of the service supply chain, and it will have an significant impact on cooperation performance [22].It is considered that it is possible to study in this area [23].Besides, through empirical research on logistics service supply chain, Gao et al. find that interaction can promote cooperation between supply chain members in upper and lower stream, reduce overall cost of supply chain, and achieve higher level of value co-creation [24].Hence, we argue that interaction is a capability for supply chain enterprises to gain competitive advantage.Thus, we propose: H1a: interaction is positively related to supplier integration H1b: interaction is positively related to customer integration H1c: interaction is positively related to internal integration

Relationship between Supply Chain Finance and Supply Chain Integration
Supply chain finance, as an important means to deal with financing difficulties, has effectively solved the fund problem of many small and medium-sized enterprises since the launch of the market.The traditional enterprise financing service is provided by the bank, while the current supply chain finance is now making the capital suppliers more diversified.In order to build a more competitive service supply chain platform and serve customers better, many supply chain service integrators have started to provide supply chain finance service.Unlike the traditional "1+N" model of the bank and also different from the internet financial model based on big data such as Alibaba and Tencent, the supply chain service integrators make use of their good credit qualifications, sufficient cash flow and other resource advantages to get credit from the bank, and then provide funds for customers who cannot get financing from banks or other channels.
Facts have proved that supply chain finance is quite helpful for startups.In entrepreneurial stage, startups do not have strong ability to resist risks and gain stable returns, which leads to the failure of the startups to obtain a higher credit rating, so it is hard for them to get bank loans.By the help of supply chain finance, startups can timely get valuable funds through the supply chain service integrator as an intermediary.
Tang et al. research on the financial service in the logistic supply chain by analyzing the small and medium-sized enterprises through the game model, and they draw the conclusion that the development of logistics finance can strengthen the overall integration of supply chain [25].Peng et al. study and demonstrate that the supply chain finance model of iron and steel industry has a positive impact on the performance of its supply chain integration [26].Yu et al. put forward the function mechanism of supply chain finance to supply chain integration, and demonstrate that supply chain finance can not only promote the supply chain integration through the flow of funds, but also through information flow and logistics [22].Thus, based on the theoretical basis above we propose: H2a: supply chain finance is positively related to supplier integration H2b: supply chain finance is positively related to customer integration H2c: supply chain finance is positively related to internal integration

Theoretical Model
Based on the theoretical research basis and hypothesis above, the overall research model is shown in Figure 1.To be mentioned that, due to space constraints, the relationship between supply chain finance and interaction, as well as the indirect effect of interaction on supply chain integration as the intervening variable, will be further studied in the future.

Questionnaire Design and Measure
The purpose of this paper is to study the impact of interaction and supply chain finance on supply chain integration in the service supply chain.To ensure the reliability and validity of the test scale, most of the questionnaire items used for the measurement of the constructs were adopted from previous studies in the field of supply chain management.The questionnaire is shown in Appendix A.
Items for the interaction variable were selected from Song et al. and Gao et al.
which includes seven questions [19] [24].Items for the supply chain finance variable were selected from Song et al. including seven questions also [19].Supply chain integration was divided into three parts: supplier integration, internal integration, and customer integration, in which supplier integration included four questions, internal integration included three questions, and customer integration included four questions, all of which were selected from Flynn et al. [2].All constructs were measured using a five-point Likert scale.All questionnaire items were marked between strongly disagree (= 1) and strongly agree (= 5) except for information sharing items, which are marked between totally not (= 1) and quite extensively (= 5).Since the initial questionnaire drawn from English, the items were translated into Chinese by one person, the Chinese version was then

Sampling and Data Collection
Different from previous empirical researches on supply chain integration which are based on Western economies, this study focuses on China.Using a large scale empirical study, 65 startups located in Pearl River Delta area, Guangdong Province were investigated.To obtain a representative sample, enterprise yellow pages were used.Besides, relation resources of MBA and EMBA also contribute to our sampling pool.For each randomly selected respondent, we identified a key informant, only those with a title such as president or CEO, vice president, manager, or director that were knowledgeable enough about the firm and its supply chain's internal and external processes were accepted.A profile of the respondents is presented in Table 1 and Table 2, from which we can see that the respondent firms represent a variety of industries, and most of the respondents have been in their position for at least 3 years which indicates that they should be knowledgeable enough about the information requested.
To assess potential late response bias, early and late responses were compared in terms of number of employees, physical assets and annual sales, with a t-test showing no significant differences.Besides, the potential for common method bias was assessed since there was one informant each organization.

Reliability and Validity
The reliability and validity of the data must be tested when the data are used to verify the structural equation.From the tables it can be seen that, the model fit indices were χ 2 /df = 1.935,CFI = 0.981, RMSEA = 0.021, RMR = 0.006, PNFI = 0.580, PCFI = 0.632.Thus, the model was acceptable, revealing convergent validity [27].Furthermore, all the standardized estimates of the measurement items were great than 0.5, and the t-values were all greater than 2.0, and each item's coefficient is greater than twice its standard error.While Bagozzi and Yi suggested that each factor loading should be greater than 0.50 and all of our 33 items are greater than 0.5, thus we satisfied the more detailed criteria set by several other studies as indicated above.Therefore, our constructs have convergent validity.Since all modification indices provided by AMOS revealed no parameters that could be released to improve model fit significantly, the discriminant validity was verified.Furthermore, the average variance extracted (AVE) for each construct was greater than the squared correlation [28], as shown in Table 6.

Analysis and Results
This study intended to assess the relationship of the 5 variables: interaction, supply chain finance, supplier integration, internal integration, and customer integration using SPSS 19.0 and the hierarchical regression analysis method and maximum Pseudo-Likehood method is used to estimate the value of model indices and path coefficients.
To sum up, the hypothesis H1a, H1b, H1c and H2b are supported, while H2a and H2c are rejected.The overall results are shown in Table 8.

Discussion
1) Influence of Interaction on Supply Chain Integration.
The key significance between the interaction and supply chain integration has been widely recognized by the theoretical community, but empirical research targeting the special group of start-up companies is very scarce.Through the study of the relationship between interaction and supply chain integration, we found that interaction has positive impacts on supplier integration (p < 0.001), internal integration (p < 0.001) and customer integration (p < 0.001), that is, H1a, H1b and H1c get support.This means that startups can enhance the profundity and level of supply chain integration by enhancing their interaction with service integrators and using service integrators as the medium.
In the service supply chain, the relationship between supply and demand is no longer a simple upstream-downstream relationship, but a mutually dependent commercial-ecology.For startups, from the process of interaction, they not only regard supply chain service integrators as service providers, but also collaborators who help their partners acquire difficult-to-acquire capabilities, knowledge and resources, and build social networks.Correspondingly, supply chain service integrators can learn more about the development pain points of startups, excavate market demand, and innovate service products in this process.Therefore, through interactions, service integrators and startups can share their own experiences, knowledge and capabilities to face the fierce market competition together and realize corresponding value appeals.
2) Supply Chain Finance Impact on Supply Chain Integration Discussion Although some scholars have suggested that there is an interaction between supply chain finance and supply chain integration, there are few studies to Table 8. Results Summary. No.

Hypothesis Content Result
H1a Interaction has a significant positive influence on Supplier Integration Supported H1b Interaction has a significant positive influence on Internal Integration Supported H1c Interaction has a significant positive influence on Customer Integration Supported H2a Supply Chain Finance has a significant positive influence on Supplier Integration Rejected

H2b
Supply Chain Finance has a significant positive influence on Internal Integration Supported

H2c
Supply Chain Finance has a significant positive influence on Customer Integration Rejected empirically verify the relationship between them, especially for the startups who have the most urgent need for supply chain financial services.This study found that supply chain finance has a positive effect on internal integration (p < 0.001) through research on the relationship between supply chain finance and supply chain integration.This means that in Chinese context, if startups can improve the level of supply chain finance cooperation with their service integrators, that will help startups to realize internal integration.In reality, there are always some certain "cost depression" in the supply chain.These "costs depression" are often small and medium-sized enterprises with unstable capital chains.These startups have become the bottleneck that restricts the development of supply chain, affecting the stability and financial cost of the supply chain.For startups, they have very good prospects for development, but they are often short-funded because of the adverse payment policies of upstream and downstream companies.In order to help startups solve financing problems, supply chain service integrators use their own credit qualifications as guarantees to provide startups with new financing channels, which not only enriches the means of profit, but also promotes the overall development of the service supply chain.
Besides, integrating supply chain financial services into supply chain management is also an effective way to control supply chain costs.With the help of supply chain finance provided by service integrators, startups can make loans through items such as orders or inventory which cannot be mortgaged by themselves before.In other words, supply chain finance service converts uncontrollable risks into controllable risks and converts uncontrollable costs into controllable costs.To sum up, supply chain finance can provide startups with valuable liquidity funds to better carry out production and business activities, allowing the companies to improve their internal integration and optimizing the overall performance of the supply chain.

Management Inspiration
Based on the empirical analysis results, this study draws the following management implications: 1) The existence of interaction facilitates the realization of supply chain integration.The global manufacturing industry is facing severe challenges at present and it is imperative to seek industrial upgrading.On the other hand, the demand for industrial upgrading has prompted the transition of traditional supply chains to new service supply chains.In the kind of supply chain, supply chain service enterprises play an important role in resource integration and information transmission.Upstream suppliers and downstream customers can directly interact with supply chain service enterprises to achieve their own demands, which help them to get rid of the complex traditional "1-to-N" mode.For Startups, they must be aware that outsourcing the non-core businesses to supply chain service integrators can enable them to get higher efficiency of resource utilization and better get through the "infancy" period.On other words, the good interaction between startups and supply chain service integrators can help them focus on the construction of core competitiveness and deepen the level of supply chain integration.This kind of interaction can also enable both parties to share their own experiences and capabilities and face problems and dilemmas together.On this basis, start-up companies can achieve their own faster growth, and service integrators can build a more comprehensive service supply chain platform to expand more service projects and realize a "multi-win" situation.
2) Supply chain finance can solve the financial difficulties of startups, thereby promoting the production and operation activities of enterprises, and achieving better internal integration of startups.Most startups are small in scale and have poor ability to resist risks.What's more there is no relevant credit record in the bank, which makes them impossible to obtain loans from the bank.Under such adverse conditions, the supply chain finance service provided by the service supply chain integrators solve the urgent needs of the startups.However, the empirical results of this study shows that supply chain finance does not have a significant effect on the overall integration of supply chain.We consider the reason is that many startups are still using traditional financing ways and lack of understanding of supply chain finance.Therefore, start-up companies should early establish the sense of supply chain finance and use that way to revitalize stock assets and expand financing channels, so as to achieve a higher level of internal integration, and improving the overall performance of supply chain

Conclusion
In this paper, we investigated the impact of interaction, supply chain finance on supply chain integration using the data collected from 65 startups enterprises in the Pearl River Delta Region.We study and explore the relationship with the tool of structural equation modeling and get some practical value of research findings: Firstly, interaction has a significant positive impact on all the three dimensions of supply chain integration, which means that startups should improve the level of communication and cooperation with partners to enhance the degree and levels of integration of the supply chain, and to better cope with the uncertainty of the external environment.Secondly, supply chain finance has a significant positive influence on internal integration, which means that if startups can improve the level of supply chain finance cooperation with their service integrators, that will help startups to realize a better internal effectiveness.Lastly, the results show that the impacts of supply chain finance on supplier integration and customer integration are not significant for startups now under China's market condition, which does not negate the importance of supply chain finance.We speculate the differences might be related to the fact that many startups are still using the traditional ways to financing while they lack full understanding of supply chain finance.

Limitation
The study has several limitations which open up venues and stimulus for further research, which mainly reflected in the following aspects: 1) The indirect value of interaction, this study only considered the direct effect of interaction on supply chain integration for startups, which may have underestimated the indirect effects of supply chain finance through the interaction, thus the indirect value of interaction could be further explored in the future study; 2) Wider geographical and cross-regional market segmentation of research subjects, the research model of this paper is based on the startups enterprises in Pearl River Delta Region, which limits the conclusions to promote in wider region because of the administrative region segmentation in China, and to draw more general conclusions, wider geographical and cross-regional market segmentation could be explored in the future study.
