Individual firms perform production and operation activities through relationships with other companies, ie, buyer-supplier relationships. Companies would pursue competitive advantage by using combined capabilities through supply chain networks. In establishing partnership with external companies, we try to operate buyer?supplier relationships efficiently by increasing the level of connectivity among related companies based on information sharing within the networks. Because the supply chain environment is very uncertain and vulnerable, companies have to respond to these changes by increasing their agility and robustness to deal with them.
This study implies that information sharing affects the quality of buyer-supplier relationships in the supply chain and also affects robustness and agility in order to respond to an uncertain environment. In this process, the performance of the company is determined, and the characteristics of the supply chain have a complex impact on the performance. Therefore, this study analyzes the effect of information sharing and buyer-supplier relationship on business ecosystem in this operating situation
In this study, the research model was set up to analyze the operating situation of this context, and the measures constructing the factors introduced in the research model were transformed into the questionnaires and then the empirical survey was conducted.
In this study, six primary vendors were selected and the questionnaires were surveyed on 40 trading companies of each vendor in order to survey the business ecosystem of Daegu and Gyeongbuk province. The data collected from the 240 companies were tested by the structural equation models using AMOS.
The following conclusions were obtained from the empirical analysis conducted in this study.
First, information sharing among suppliers in the supply chain had a significant effect on buyer-supplier relationship, and information sharing had a significant influence on agility and robustness on the firms in the supply chains..
Second, agility had a significant effect on firm performance, but robustness did not.
Third, the mediating effect of agility was supported in the effect of information sharing and buyer-supplier relationship on performance, but mediating effect of robustness was not.
Fourth, as a result of dividing the leadership type of lead company leading the supply chain into transformational leadership and transactional leadership and making a difference test on the constitutional concept of the research, transformational leadership ecosystem showed better performance.
Fifth, the restructuring of the structural equation model with the detailed attributes of buyer-supplier relation, and the adjustment effect of each control variable, showed that the control effect of uncertainty has the most effect. Therefore, management of buyer - supplier relation is important to cope with uncertainty.
