Research On The Mechanism And Optimization Of Patent Protection Affecting The Innovation Bias Of Enterprises

First,this paper constructs a theoretical model of corporate innovation bias.The core of its research is whether there is an innovation bias in the enterprise.Secondly,based on the theoretical model,this paper builds an extension model by introducing patentable standards,and studies the mechanism by which patentable standards affect the innovation bias of enterprises.Combining with the research results obtained from the theoretical model,this paper uses the panel data of 2007-2017 A-share listed high-tech companies for empirical testing,further explores the innovation bias of enterprises and demonstrates the impact of patent protection on corporate innovation bias.Finally,the research conclusions of this article provide a scientific theoretical basis for the government to improve the patent system and optimize the patent policy.It is of great significance for China to build an innovative country and promote high-quality economic development.In the basic theoretical model,based on the perspective of complementary innovation,this paper constructs a model of corporate innovation bias to explore whether there is an innovation bias in the enterprise.On the premise of asymmetrical probability of R&D success of complementary innovative technologies,the social benefits and expected returns of companies participating in complementary innovative technology R&D,respectively.It is found that in the static and dynamic models,compared to the social optimality,companies in the market equilibrium do have an innovation bias,which will favor low-risk technology R&D,and this innovation bias will be further exacerbated in the dynamic model.This kind of innovation bias will cause a large amount of R&D resources in the market to be repeatedly wasted on low-risk technology project R&D,and inefficient investment in high-risk technology project R&D.In the extended theoretical model,this paper introduces patentable standards in the patent system,and further constructs a model of patentable standards affecting corporate innovation bias,and studies the impact of patentable standards on corporate innovation bias.It is found that with the increase of patentable standards,companies in the market equilibrium will intensify the innovation bias of choosing low-risk technology R&D.Because the level of patentable standards will directly affect the transformation of enterprise innovation results,there is a limited optimal range of patentable standards,which can not only promote the innovation enthusiasm of enterprises,but also reduce the flood of low-quality innovation results.In the empirical test,combined with the research results obtained in the theoretical model,this paper uses the data of 182 high-tech listed companies in Shanghai and Shenzhen stock exchanges in China from 2007 to 2017 as a sample to conduct a regression analysis.The bias of innovation is affected by the patent protection of internal factors and external environmental factors.In summary,when formulating a patent policy and improving the patent system,the government must not only encourage more companies to actively participate in R&D,but also guide companies to alleviate innovation bias for low-risk technology R&D,enhancing the enthusiasm of enterprises to participate in the R&D of high-risk technology projects,so that the level of innovation is multi-dimensional.At the same time,the heterogeneity of industries should be taken into account,and differential patent protection should be implemented in different industries to promote the vigorous development of innovation activities in various industries.
