Market Structure And Technological Innovation Of China High-Tech Industry

Technological innovation is a vital pushing power of economical growth and the progress of technology. This thesis studies the factual stations and future studies of China high-tech industry technological innovatin from the interaction relationship between market structure and technological relationship. Since the present of Schumpeter hypothesis, which kind of market structure is the best becoming the hotspot of industrial organization. There are more and more studies on the relationship between market concentrate index, firm size, market power and technological innovation. Many countries begin to pay attention to the contribution of different size of enterprises especially large-scale ones, the influence of market structure on technological innovation attracts more and more attention. While the studies about the influence of technological innovation on market structure attracts a little attention. But the mechanism and influence of technological innovation on market structure, especially combine one of the industries is a remarkable question.Based on this, this thesis uses the basic theory of industrial organization analysis of SCP paradigm, combine the academic analysis and emperical analysis to summarize the interalation between market structure and technological innovation of China high-tech industry:The first part is the basic theory, introduces the background and meaning of this thesis, and summarizes the academic and empirical studies, concludes relative theories of market structure, technological innovation and the relationship of them.The second part firstly introduces market structure of China high-tech industry, uses absolute market concentrate index, comparative concentrate index and the number of firm to analysize the market structure of China high-tech industry. The main conclusions are as bellows: the market structure of China high-tech industry is competitive, but the comparative scale is big; if fractionized as 17 industries, manufacture of radar and its fittings, manufacture of entired computer, manufacture and repairing of airplantes and manufacture of office equipment are origarching market structure, others are competing market structure, the difference of comparative scale between different industries is small. Secondly, it introduces the technological innovation station of China high-tech industry, analyzes the input and output index of China high-tech industry, and it concludes the input of China high-tech industry is scarce, the output efficiency is low.The third part analyzes the interaction between market structure and technological innovation of China high-tech industry. Firstly, it combines the character of high-tech industry to analyze the influence of market concentrate index, product diversity, firm size and entry and secede obstacles on technological innovation; based on the absolute market concentrate index and comparative concentrate index divides 17 subsective China high-tech industries into four different market structure, and analyze the product innovation and process innovation innovation of them to summarizeon the influence of market structure on technological innovation, the main conclusion are as follows: if market concentrate index and comparative scale are bigger than the average level of whole industry, then the product innovation and process innovation are better, if market concentrate index and comparative scale are smaller than the average level of whole industry, then the product innovation and process innovation are worse. Secondly, technological innovation influences market structure via cost, industry life cycle, patent and criterion; this thesis via klette dynamic model, uses 1995-2008 panel number of China high-tech industry on 17 industries to analysis the dynamic effect of the technological innovation to market structure. The conclusions are as follows: both short-term and long-term analysis indicates that technological innovation pricks up competition, this may relates with the character of China high-tech industry. Moreover market scale and country-owned proportion influence market structure, market scale pricks up competition and country-owned proportion restrict competition. One must be put forward is that the influence of technological innovation on market structure is not notable, so there must be some factors that forbid the function of technological innovation. The possible reasons may as follows: firstly, high-tech products are more easily to imitate and copy and the cost is cheap, this may make knowledge imitation very serious, it will reduce the enthusiasm of innovation, innovative corporations hardly achieve the profit of innovation. Secondly, technology density of China high-tech is low, the gap between high-tech industry and low-tech industry is small, most products fetch in mature technology, so the risk of technological innovation is not big, compared with low-tech industry, ecomomical benefits of high-tech industry is not superior. Finally, many high-tech markets is atom market structure, they do not have technology and product monopoly certifications.The fourth part is the conclusions and propositions. The main conclusions are as follows: competitive market structure is the condition of China high-tech industry; to technological innovation oligarchy market structure is the best market structure; from short-term and long-term analysis technological pricks up competition, but the influence is not notable. So form knowledge right protection, building a big scale enterprises dominant, all scales of enterprises cooperating market and government policy collection conclude the propositions of China high-tech industry development.
