The Effects Research On Market Structure On Innovation Performance Of Sichuan High-Tech Industry

In contemporary society, the technical elements determines the level of social development, innovation and technological achievements obtained determines the speed of progress and development. High-tech industry as the main field of innovation achievements, has become an oriented technological progress of a country or region.In recent years, in order to optimize the economic industrial structure, promote economic development and enhance its overall national strength, the world countries will enhance the level of their science and technology as the first priority, and increase the investment of technological innovation and innovation to improve output efficiency. In the process of rapid development of High-tech industry in Sichuan Province, enterprises in the industry continue to enter and exit, the number of enterprises and enterprise scale constantly changing, market structure also will be undergoing constant change.Therefore, by use of reasonable methods on technical innovation performance of high-tech industry in Sichuan Province, it is meaningful to evaluate the impact of market structure on innovation performance, which is helpful to enhance technological innovation input and output level of Sichuan's high-tech industry and to achieve the province's science and technology continued progress, industrial structure optimization, and overall economic development.This paper started with review and summarize the previous studies. The technological innovation is divided into two stages:research development and achievements transformation; Secondly,it adopted panel data of Sichuan's high-tech industry during 2007-2012,were constructed two-stage DEA model, select the appropriate creative input indicators and output indicators, analyzes, estimates the value of a two-stage innovation performance;Finally, according to the DEA model and the value of innovation performance, adding control variables like business performance, ownership structure, access barriers and so on, building multiple linear regression model, empirically analyze of the effect of structure market on innovation, respectivelyon two phases.(1) According to DEA model estimation results, the overall innovation performance of the two-phase research and developmentof high-tech industry in Sichuan showed a steady upward trend. Specific to the various fields of high-tech industry, the top five industries in two-stage technological innovation perform quite differently, computer and office equipment industry shows highest in both stages of innovation performance, and the aerospace industry shows lowest in the stage of R&D innovation performance, the medical equipment and instrument manufacturing performs lowest in the stage of transformation.(2) Multiple linear regression model showed that due to the different characteristics of each fields, the market structure of various sub-sectors has different impact on the two-stage innovation. From the whole high-tech industry in Sichuan, the market structure (industrial concentration) has significantly positive impact on innovation performance in research and development stage, and significantly negative impact on innovation performance in technology transfer stage.Based on the above findings and the actual situation in Sichuan Province, the following policy suggestions are as follows:? Establish a reasonable evaluation system of input and output, optimize the structure of the input factors of innovation, and improve the efficiency of output. ? Improve the laws and regulations of Sichuan Province, and optimize the system of innovation and encourage policy, create a good industrial environment, and promote the coordinated development of the five major high-tech industries in Sichuan Province.? Sichuan aerospace and equipment manufacturing industry should be appropriate to increase the size of enterprises. ? In addition to the Sichuan Aerospace Industry and equipment manufacturing industry, the other four major high-tech industry should be created and formed to large enterprises dominant, the coexistence of medium and small enterprises diversified market structure.
