| Innovation is the inexhaustible driving force for national progress and the necessary condition for enterprises to create new value.Enterprise innovation includes idea innovation,management innovation and technology innovation,among which technology innovation is the core of innovation.The technological innovation behavior of enterprises is influenced by the degree of legal system,the fairness of market competition,the strength of intellectual property protection and other external environments.Patent enforcement insurance strengthens patent protection,optimizes the external environment of enterprise technological innovation,and provides risk protection for enterprise technological innovation.However,it is not suitable for market conditions to blindly pilot patent enforcement insurance,and tightening patent protection will hinder technological exchanges between enterprises,and even cause the technological innovation level of enterprises to retreat.Therefore,it is of great significance to study the results of the pilot work of patent enforcement insurance at the present stage for the subsequent strategic and focused implementation of patent enforcement insurance.This paper reviews relevant literature research at home and abroad.First,it defines the concepts of patent protection,patent enforcement insurance and technological innovation.Based on competitive advantage theory,externality theory and signal transmission theory,this paper analyzes the effect of patent enforcement insurance on enterprise technological innovation,and puts forward research hypotheses.Secondly,the development status and existing problems of patent enforcement insurance and enterprise technology innovation in China are analyzed.Thirdly,based on the data of 1884 A-share listed companies from 2010 to2019,A differential difference estimation model is constructed to empirically test the hypotheses proposed in this paper.Research results: First,the pilot implementation of patent enforcement insurance can effectively promote the technological innovation of listed companies;Second,the effect of patent enforcement insurance on technological innovation of listed companies is heterogeneous,and the effect on technological innovation of listed companies with different capital components is not significant.It has a significant negative effect on enterprises with high industry concentration;It has a significant positive effect on the enterprises whose technology is easy to be reverse engineered.Finally,based on the research results,suggestions are proposed from the perspectives of the government,insurance companies and enterprises.The government should provide judicial assistance and regulate the operation of patent enforcement insurance.Insurance companies in the product should be timely innovation,timely reserve professionals,strengthen publicity,according to the different market conditions and service objects of flexible rate and compensation amount;When enterprises use patent enforcement insurance to manage patents,they should consider the fit degree of their patented technology and insurance products and the characteristics of the industry they are in. |
