基于R&D模型的中国知识增长效率区域差异的研究

he purpose of this paper is to explore the regional differences of knowledge growth ,and weather the areas in low technology level are catching up with the high ones. This paper estimate the stock of patent application in different areas from 2004 to 2009 by perpetual inventory method .The equation about regional differences in knowledge growth is built by Zou Zhichuang-test,accordign to China's science and technology statistics. This paper find that the production efficiency about both R&D funding and R&D staff of the high technological level areas is higher than the low technological level areas,but the growth acceleration is just in the opposite, so the low technological level areas are catching up with the high ones.And the growth acceleration of the general technological areas is the same with the high ones ,so the gap between them will become bigger.
