Research On The Influence Of Innovation Policy On The Innovation Capability Of Industrial Enterprises And The Time Lag Ffect

High-tech is the foundation of a strong country and the soul of the development trend of the Chinese nation,and scientific and technological innovation is the power of the continuous development of science and technology.With the reform and opening up,the Chinese TSRernment has always placed the development of science and technology at the center of my country’s overall development.As the vanguard of my country’s reform and opening up,the Yangtze River Delta region has always played an significant role in scientific and technological innovation.The industrial enterprises above designated size are the mainstay of a region’s economy,and their technological innovation level also represents the level of a region’s technological innovation.In this paper,976 innovative environmental policies and tax relief for industrial enterprises above designated size in the Yangtze River Delta region from 2005 to 2019 were selected as samples.Innovation policies were divided into supply-side policies and environmental policies,and a research model was established based on the Cobb-Douglas production function.By using multiple regression method to explore the supply side innovation policies,environmental innovation policy,funding,research and development personnel quantity influence on the innovation ability of industrial enterprises,in order to further explore the factors of promoting innovation policy influence,and synthetic control method was used to study the Yangtze river delta regional integration strategy for innovation of the impact of policy implementation.Finally,the paper analyzes the timelag effect of supply side innovation policy,environment side innovation policy,innovation capital investment and number of r&d personnel in the process of enterprise innovation.The following conclusions are drawn: first,among the innovation policies,the environmental innovation policy has the most significant impact on the innovation capability of industrial enterprises,with an impact coefficient of 1.125,and that of the supply innovation policy is0.709.In terms of enterprise investment,the number of R&D personnel has the most significant influence on enterprise innovation ability,and the influence coefficient of innovation capital investment is 0.642.Second,regional integration strategy strengthens the role of innovation policy in enterprise innovation.The implementation effect of innovation policies in a region is closely related to the degree of local integration,because the improvement of the integration degree in the Yangtze River Delta weakens the information asymmetry between regions and speeds up the flow of production factors in the region,so the policy implementation has a stronger stimulating effect on enterprises.Thirdly,different factors have different time lag effects on the innovation ability of industrial enterprises.From the perspective of the time of effect,tax exemption and innovation policy have the fastest impact,followed by innovation input,and finally,the number of R&D personnel.In terms of the duration of impact,the number of r&d personnel has the shortest duration,followed by innovation policy,followed by innovation investment,and the tax breaks have the longest duration,but there is significant volatility in the middle.
