The Mechanism Of Intellectual Property System And Economic Growth

Since 1990's, the research about the impact of intellectual property system in TRIPS on the economic growth has been got widely attention. Under the background of carrying out the intellectual property strategy in China, it is of great signification to deeply and objectively realize the relation between intellectual property system and the economic growth.This research is based on the new economic growth theory, adopting the methods of macroeconomics, mathematical economics and law science, to do the research of the inner relation between intellectual property system and the economic growth. It has initiatively construct index system of the strength of intellectual property protection in China, established the motive model of economic growth with the endogenous economic growth model of intellectual property, exposed the inner system of economic growth affected by intellectual property system. It has empirically analyzed the effects of intellectual property system to the technology innovation and technology diffusion in China, and the contribution of the intellectual property system to the economic growth in China. It has finally pointed out the two-side effect and complexness of intellectual property protection on the economic growth, analyzed the reasons why the intellectual property system has not played an important role sufficiently in China. On the base of the research, it has put forward the policy suggestions to better the intellectual property system of China.The main conclusions of this research are as follows: (1) The intellectual property protection index of a country or district should integrate the intellectual property legislation index and enforcement index. (2) The optimal level of intellectual property protection in one country depends on its level of economic development in a non-monotonic way, exhibiting an U-shaped curve, first decreasing and then increasing. (3) As the key guaranteeing system of technology progress, intellectual property system indirectly promotes economic growth through the technology innovation and technology diffusion. (4) The Chinese intellectual property system has effectively promoted its technology innovation and technology diffusion in a certain extent. (5) The contribution rate of the intellectual property system to the economic growth in China within last 20 years is 32.7%. (6) The effect of intellectual property protection on the economic growth is of two-side. There are not only positive effects, but also negative effects, and the final effects are integration of both. The sufficient exertion of positive effects hangs on one country's given economic and law conditions.The beneficial research has put some foundation for the further research about the relation between intellectual property system and the economic growth, and has provided some theorical and empirical basis for carrying out the intellectual property strategy in China.
