| Science and technology(S&T) is the primary productive force and the main driving force of economic growth. And S&T investment is the basic premise and necessary condition of scientific innovation and technological progress. So S&T investment plays an important role on economic growth. At present many countries or regions regard increasing S&T investment as the principal means to promote economic growth and improve the comprehensive competitiveness. Through analysis, this paper trys to know more about the conditions of S&T investment and economic growth for the east, middle and west region in China, and find out the difference of the S&T investment influence on economic growth in different regions of China.The data of GDP capital labor and R&D stock for 30 provinces from 1998 to 2006 in China were used to do the empirical research on the regional disparities of S&T investment influence on economic growth by applying Panel Data model analysis. The paper includes five parts: PartⅠ: Introduction, study background, purpose, meaning and study summary at home and abroad are introduced ; PartⅡ: Basic concept and theory. In this part, the meanings of economic growth and S&T investment have been expounded, at the same time economic growth theory, interaction mechanism of economic growth and S&T investment are analyzed; PartⅢ: The situation of economic growth and S&T investment in China. This part introduced the development of economic growth and S&T investment in our country, and the economic and S&T situations in eastern,middle and western region of our country are analyzed and compared; PartⅣ: Empirical research of regional difference of S&T investment on economic growth. In this part, capital, labor and R&D stock are used as independent variable and GDP as dependent variable to do empirical research by applying Panel Data model analysis for each region. At last each regional model was calculated; PartⅤ: Policies and proposals of speeding up S&T investment to promote regional economic growth. This part pointed out the related policies basis on study.The last part included results.summary and further study direction. The major achievements of this research as followings:(1)The level of S&T investment is low and regional difference of S&T investment is obvious in China at present. From absolute quantity, R&D expenditure and R&D staff investment of eastern area is far more than middle and western area.(2)The influence of S&T investment on economic growth is very obvious in China, but in most provinces its influence is weaker than capital's and labor's, moreover this trend is more and more obvious from east to west.(3)R&D stock output flexibilities are: east area>middle area>average level of the whole country>west area, so the S&T investment influence on economic growth are: east area>middle area>average level of the whole country>west area.(4)Not only the S&T investment influences on economic growth for different areas are different, but also in the same area the S&T investment influences on economic growth for different provinces are various. For example in Shanghai and Tianjin R&D stock output flexibilities exceed 0.65, while the ones of the other eastern provinces are only between 0.20 and 0.60. |
