An Empirical Study On The Effect Of Supply Chain Concentration On Technological Innovation Of Manufacturing SMEs

Supply chain is an important form of enterprise resources in the market economy.It is also one of the focus points of the government to promote enterprise technological innovation and deepen supply-side reform in recent years.At present,the development of the COVID-19 has entered a new stage,and China’s trade environment has undergone major changes.Exploring the impact of the manufacturing supply chain system on the technological innovation of SMEs and helping the macroeconomic transformation and upgrading is a common concern of the government and enterprises.Focusing on the impact of manufacturing supply chain concentration on technological innovation activities of small and medium-sized enterprises,this paper introduces the relevant market background,business scope,research status and basic theory,and establishes a linear regression analysis model from the perspective of supplier concentration and customer concentration,with the basic relationship hypothesis and heterogeneity analysis hypothesis as the starting point of the study.Among them,the basic relationship hypothesis is divided into three aspects:first,the impact of supplier concentration on enterprise technological innovation;Second,the impact of customer concentration on enterprise technological innovation;The third is the hypothesis of regulating the nature of enterprise property rights.In addition,considering the differentiation of the relationship between supply chain concentration and technological innovation,the heterogeneity study is conducted from two perspectives:the economic region of the enterprise and the degree of marketization of the enterprise location.Select the business data of 622 manufacturing SMEs from 2010 to 2021 as a sample to form panel data,totaling 7286 items.In the model,technology R&D investment is the explanatory variable,and supply chain concentration is the explanatory variable.On the basis of practical research,this paper summarizes the full text,puts forward policy implications,and looks forward to the development trend,research methods and research data changes of the phase difference business in the future.The main conclusions of this paper are as follows:First,supply chain concentration has a significant impact on technological innovation of small and medium-sized manufacturing enterprises.Compared with private enterprises,supplier concentration has a smaller impact on technological innovation of state-owned enterprises,and customer concentration has a smaller impact on technological innovation of state-owned enterprises.The nature of property rights has a significant regulatory effect.The partial regression coefficients of supplier concentration,customer concentration and enterprise technological innovation are-0.0097 and 0.0142,respectively.Second,no matter the degree of marketization is high or low,the concentration of suppliers is negatively related to the investment in technological innovation of enterprises.The partial regression coefficients of the regions with high degree of marketization and low degree of marketization are-0.0229 and-0.0393 respectively,and the significance level is 5%and 1%respectively;The latter is more affected by negative impact than the former.In terms of customer concentration,the partial regression coefficient of regions with high degree of marketization is 0.0117,and the partial regression coefficient of regions with low degree of marketization is 0.0246.Regions with low degree of marketization have a stronger positive promotion effect.Third,the supplier concentration is negatively correlated with the technological innovation of enterprises in the east and central and western regions.The partial regression coefficients of enterprises in the east and central and western regions are-0.0207 and-0.0318,respectively.Enterprises in the central and western regions are greatly affected by the supplier concentration.In terms of customer concentration,the technological innovation of enterprises in the east and the central and western regions is positively affected by it.The partial regression coefficient in the east is 0.0314,and the partial regression coefficient in the central and western regions is 0.0262.
