| With the global economic integration,the product life cycle shorten,development present personalized requirements of customers,the enterprise to be in a growing market environment for development,we must build supply chain advantage,rely on the strength of supply chain to enhance enterprise competitiveness.Supply chain integration,especially as an important stakeholder corporate clients and its concentration is often to enterprise’s strategic management and financial decision-making and influence,and the bank borrowing as an important content of corporate financial decisions,decides the survival and development of enterprises.Some enterprises in our country are more dependent on customers,and the concentration of customers is closely related to the stability of the supply chain.When assessing the performance of the borrower,banks consider the stability of the supply chain to a large extent.Therefore,Concentration on the impact of corporate bank loans as the research direction to adapt to the needs of the times.Although there are many researches on the economic consequences of customers in China at present,there is less literature on the relationship between customer concentration and bank borrowing.Based on this,this article explores concentration,the impact of bank loan to the enterprise customers,and the first attempt to study environmental uncertainty whether the factors influence customer concentration and the relationship between the bank loan.This article first sorts out domestic and foreign research literature on the relationship between customer concentration and bank borrowing,environmental uncertainty,and bank borrowing,and makes full use of agency theory and other related theories.It focuses on environmental uncertainty,customer concentration,and bank borrowing.The association between the data is demonstrated and the hypothesis is proposed.With reference to China’s economic trends,the data of 2012-2016 A-share companies in Shanghai and Shenzhen were extracted to conduct empirical research.After screening,a total of 7,645 sample data of 1,529 companies were identified.This data was analyzed empirically using spss software and customer concentration was achieved.An empirical test of the relationship with bank borrowings.At the same time,in order to study the regulatory role of environmental uncertainty on the relationship between corporate customer concentration and bank borrowing ability,this paper adds relevant colocation items on the basic model for empirical analysis.And in the final use of the Herfindahl index to replace the independent variables for robustness test,and fully guarantee the reliability of empirical results.The empirical results show that there is a significant positive correlation between variables measuring customer concentration and variables measuring bank borrowings,and there is a significant negative correlation between the measurement of environmental uncertainty and the measure of customer concentration variables and bank borrowing variables.This confirms the view that companies with higher customer concentration have stronger bank borrowing capabilities,and the lower the environmental uncertainty,the stronger the influence of customer concentration on bank borrowing capacity.This research result enriches the relevant theoretical research to a certain extent,and provides reference and reference for the actual decision-making of the company,especially in the face of volatile changes in the market environment.According to the research conclusions,the government should actively grasp the development of economic development,mitigate the economic fluctuations caused by environmental uncertainties,establish a loan decision mechanism and risk assessment method that the bank should adapt to the company,establish a comprehensive evaluation system,and strive to achieve a bank Systematic information sharing,enterprises should strengthen supply chain management,and take “win-win” concepts as guiding ideology and other countermeasures. |
