Research On The Influence Of Manufacturing Supplier Market Concentration And Property Right Concentration On Enterprise Innovation Investment

At present,the world economy is in a complex and changeable economic situation.In order to cope with the rapid changes in the market environment brought about by the era of knowledge economy,manufacturing enterprises are facing new innovation challenges.With the increasing integration of the manufacturing industry,the impact of supply chain partners such as suppliers on enterprise innovation can not be ignored.From the perspective of supplier market concentration and supplier property right concentration,this thesis studies the relationship between them and enterprise innovation investment,and explores the regulatory effect of government subsidies and the nature of property rights on their relationship,so as to provide a new research perspective for the improvement of enterprise innovation investment level.Therefore,this study has certain theoretical value and practical significance for enterprises to integrate the supplier structure and improve the level of innovation investment.Firstly,this thesis combs the relevant literature and theories of supplier market concentration,supplier property right concentration and enterprise innovation investment.On this basis,this thesis puts forward the research hypothesis that the supplier market concentration,the supplier property right concentration,the enterprise innovation investment.And the government subsidies,the nature of property rights play a regulatory role.Secondly,a total of 1142 relevant data of China’s manufacturing listed companies from 2015 to 2019 are selected for empirical analysis to verify the research hypothesis of this thesis.Finally,according to the results of empirical analysis,this thesis draws the research conclusions,and puts forward relevant policies and suggestions to enhance enterprise innovation investment based on the two perspectives of enterprise management and government regulation.Suggestions from the perspective of enterprise management include: reasonably arranging the supplier structure,decentralizing the concentration of state-owned property rights of suppliers,actively seeking subsidies and reasonably planning the use of subsidies,and formulating strategies from the perspective of innovation.Suggestions from the perspective of government regulation include: differentiated government subsidies,strengthening the supervision of enterprise information disclosure,establishing a screening mechanism for subsidy objects,and supervising and evaluating the efficiency of subsidy utilization.The conclusions of this thesis are as follows: first,supplier market concentration has a significant inhibitory effect on enterprise innovation investment.Second,the concentration of state-owned property rights of suppliers has a significant inhibitory effect on enterprise innovation investment.Thirdly,government subsidies can play a regulatory role in the relationship between supplier market concentration,supplier property right concentration and enterprise innovation investment.The regulation effect is as follows: government subsidies will weaken the inhibitory effect of supplier market concentration and supplier state-owned property right concentration on enterprise innovation investment.Fourth,compared with non-state-owned enterprises,the negative correlation between supplier market concentration of state-owned enterprises and enterprise innovation investment is more significant;Compared with non-state-owned enterprises,the negative correlation between the concentration of state-owned property rights of suppliers of state-owned enterprises and enterprise innovation investment is more significant.
