Market Structure, Competition In The Corporate R & D And Innovation Performance

Technological innovation is one of the main sources of economic growth and the progress of human society. This thesis studies the relationship among corporate R&D, innovation and efficiency from the perspective of market structure. Since the pioneering tradition of innovation since Schumpeter, corporate strategy choice of R & D behavior under different market structures has become the hot spot theory of industrial organization, and has gotten a lot of conclusions in the relationship between innovation and growth,firm size, market power. Meanwhile, the issue of technical contribution in China's economic growth "miracle" since the reform and opening up "miracle" is also the important area of research in recent years, and the performance of technological development in China since reform and opening up is much worse than the economic growth performance.Based on this, this thesis uses the basic theory of industrial organization analysis of SCP paradigm, using the theoretical model and empirical analysis methods to analyze the relationship between innovational efficiency and the market structure in China:The first part is the basic theory, introduces the theme of this paper and methods, and research results expected, carries out the related literature and expends in theoretical and empirical research. The technology development since China's reform and opening up is briefly discussed, and the study of our scientific and technological innovational efficiency is reviewed.The second part is the part of the theoretical model. Chapter 3 studies the strategies choice of R&D and the differential of efficiency using the improving mixed structure model. Setting an Objective function to reflect the degree of market to differ State-owned enterprises (SOEs) and private enterprises, and a technological spillover cost function to reflect Intellectual property protection (IPRs), the Chapter studies the differential of R&D competition and cooperation under different nature of ownership, and the relationship between market entry and innovational efficiency. Chapter 4 studies vertical innovation under imperfect competition. Considering of the uncertainty of innovation, the technological preference of upstream and downstream firms, studies the R&D investment, social efficiency under different vertical integration. The third part is the part of empirical study. Chapter 5 studies the innovational efficiency of China's High-Tech industries using 1996-2008 regional data by fixed effect model and random effects model methods. In this Chapter, we construct the R&D expending Pricing Index, calculate the R&D capital stock and the elasticity of innovational output, and study the reflection of policies supporting, technical renovation and technology obtained on innovation. Chapter 6 studies the relationship between innovation and firm scale, market power using Chinese industrial enterprise database by Tobit model. The last part is the conclusion.
