The High-tech Industry Agglomeration Effects On Economic Growth

The 21st century is the era of knowledge economy, high-tech industry is a pillar industry of the era of knowledge economy, the leading role to economic development, high technology industry has become a new economic growth point of the world. From 2000 to 2013, the number of high technology industry in China increased by 173.45%, workforce grew by 230.02%, total profits increased by 974.85%. Data show that the high technology industry in recent years, presents the fast growth the tendency. Cluster development is the common characteristics of high technology industry, but in different area, the high-tech industry agglomeration effects on economic growth performance on business members of the differences. This study helps to clear the high-tech industry agglomeration effect on the differences of different regional economic growth and provide reference for high technology industry planning and layout.Based on high technology industry in our country as the research object, measure industrial concentration coefficient value to prove the existence of high-tech industrial agglomeration phenomenon, and adopts empirical description of current situation of the high-tech industry agglomeration in 31 provinces and cities, the empirical study of the industry agglomeration spatial geographical characteristics and differences between industries, and by measuring the panel model to analyze the existence of the industry agglomeration effect on economic growth, significant and regional difference, trying to find out guide the reasonable way of the high technology industry development in our country, to promote the high technology industry provides the basis for reasonable layout. Through the research, this paper get the following conclusion:First, plays a significant role in China’s five major high-tech industrial agglomeration phenomenon, this article through space gini coefficient and coefficient of industrial agglomeration REG estimates of China’s five major high-tech industry agglomeration level, reflect the existence of high technology industry agglomeration.Second, high-tech industrial concentration degree of industry difference and regional difference. From 1995-2013 time level, our country’s high-tech industry agglomeration level on the whole present a rising trend. From the industry level, different high-tech industry agglomeration level there are still differences, among them, the aerospace aircraft manufacturing industry agglomeration level always maintain the highest accumulation coefficient, and electronic and communication equipment manufacturing industry agglomeration level the lowest. Look from the spatial hierarchy, agglomeration high levels of industry distribution in economically developed areas.Third, from the national level, the high-tech industry agglomeration and there is some internal relationship between economic growth, in this paper, starting from the source of dynamic externalities, construct three can measure the characteristics of the structure of the high-tech industry agglomeration index, through panel data model by regression analysis. Specialization, diversification, competition and the amount of capital per capita possession of positively correlation to economic growth, but the influence of different structural characteristics of high technology industry agglomeration level existence difference, the characteristics of professional high-tech industrial cluster structure, the highest per capita output elasticity, and diversified features and competition of per capita output elasticity is almost the same, and specialized in high technology industry structure features and competition the influence of the most significant.Fourth, from the east, middle and west area level, high-tech industrial agglomeration and the relationship between the economic growth present diversity. The eastern region, other variables except lnPOR variable positive correlation with economic growth, among them, the per capita capital stock structure of per capita output of the high-tech industry agglomeration of diverse characteristics of the elastic coefficient of per capita output is the largest. Specialization of high-tech industrial agglomeration in the central region of the characteristics of the elastic coefficient of per capita output is the largest, this is the case with the national, diversified characteristics influence on economic growth is negative, but not statistically significant, competition features while the impact on economic growth is positive. In the western region of the high-tech industry agglomeration of specialization, diversified characteristics, competition and per capita capital positively correlation with economic growth, the competition characteristics of industrial cluster on the elastic coefficient of economic growth is the largest, although diversified characteristics has positive effect on economic growth, but statistically insignificant.
