The Effect Of Supply Chain Concentration On Enterprise Financial Performance And Its Mechanism

Nowadays,the market environment is more and more open and the competition is more and more fierce,and the boundary of enterprise competition is also expanding.The competition between individuals turns to the competition between complex supply chains,which drives enterprises to pay more attention to their transaction dependence with upstream suppliers and downstream customers.In this paper,supply chain concentration refers to the transaction dependence of sample enterprises on their upstream suppliers and downstream customers.It is manifested in two aspects:first,the supplier concentration,that is.the procurement dependence of sample enterprises on their upstream suppliers;Second,customer concentration,that is,the sales dependence of sample enterprises on downstream customers of their supply chain.The practice shows that the concentration degree of upstream and downstream enterprises in the supply chain affects the business behavior of enterprises,and different business behaviors bring different business results.How to maintain and maintain the relationship with the upstream and downstream enterprises and the degree of closeness,so as to help the enterprise performance,in order to maintain the competitive advantage has always been a topic of concern in the theoretical and practical circles.Based on the concentration degree established by the enterprise with its suppliers and customers,the relationship between the supplier concentration degree and the customer concentration degree and the financial performance of the enterprise as well as the mechanism of action are explored by combining with the research of the existing relevant literature.First of all,review and summarize the existing supplier concentration,concentration and the relationship between corporate financial performance mechanism and the related literature,to determine the paper supplier relationship model between concentration and corporate financial performance,customer relationship model between concentration and corporate financial performance,and the mediation effect of two groups of model corresponding to the model.Secondly,the manufacturing enterprises in NEEQ(small and medium-sized enterprise share transfer system,hereinafter referred to as the new third board),which are rarely studied,are determined as the research objects of this paper.Thirdly,on the basis of referring to the existing research results and combining with the situation of the research samples,the measurement indexes of such variables as supplier concentration,customer concentration and enterprise financial performance are set and the research hypothesis is put forward.Finally,STATA 14.0 software was used for empirical analysis,and the following conclusions were drawn:First,there is an inverted u-shaped relationship between supplier concentration and enterprise financial performance;Secondly,there is a u-shaped relationship between customer concentration and corporate financial performance;Thirdly,the influence of supplier concentration degree and customer concentration degree on enterprise financial performance through innovation ability is not significant;Fourth,supplier concentration ratio is compared to the enterprise financial performance through gross profit expense;Fifth,customer concentration ratio is compared to the enterprise financial perform ance through the turnover rate of total assets.Through the above research and analysis,this paper provides practical reference and reference for manufacturing enterprises,and promotes the improvement of financial performance of enterprises by establishing or adjusting the transaction dependence between enterprises and upstream and downstream enterprises.
