Research On The Effect Of Enterprise Innovation On Productivity In The Perspective Of Innovation Value Chain

With the implementation of innovation-driven strategy,the traditional driving force of China’s economic growth is decaying,the industrial structure is still in the low-end of the industrial chain,the development model of economy is from material consumption,imitation to innovation-driven change.The level of scientific and technological innovation has been increasing,but the country’s overall labor productivity is low.The quality and efficiency of the development is the key to economic growth,low productivity has become the current problems.At the same time,the enterprise is the subject of innovation.the country also put forward many strategies to improve the firm’s productivity.Therefore,how to improve labor productivity and promote economy through innovation has become an urgent problem to be solved.The paper is to do research on the effect of innovation on productivity in the perspective of innovation value chain.The source of Innovation is knowledge.The process of innovation includes knowledge sources,the transfermation of knowledge and the use of knowledge.Therefore,the process of enterprise innovation is essentially knowledge of the use of the process.Meanwhile,the process of innovation is the realization process of value.According to the theory of IVC,the realization of value includes three stages:creative production,creative transformation and creative diffusion.The performances of the three stages in innovation are innovation input,innovation output and productivity.According to the theoretical analysis,the enterprise innovation questionnaire data of Jiangsu,and the model of CDM,the paper constructs the innovation input equation,innovation output equation and productivity equation to research the effect of enterprise innovation on productivity.The results are as follows,(1)The regression results of firm characteristics and innovation intensity to innovation decision shows:the industry and size have significant impact on innovation decision and innovation investment;whether it belongs to high-tech enterprises only have a positive impact on innovation investment.(2)The results of the impact of innovation input on innovation output shows:costs of innovation and the innovation knowledge of firm itself,customer and research institution have positive impact on product innovation;the innovation knowledge of supplier have negative impact on product innovation;costs of innovation and the innovation knowledge of supplier and competitor have positive impact on process innovation.(3)The regression results of the impact of innovation output on productivity shows:product innovation and process innovation have significant positive effect on productivity.
