20世纪80年代的经济增长理论强调了技术、知识溢出和人力资本外部性对于经济增长的促进作用。而这种知识溢出效应在城市中将更加显著(城市中人与人之间的信息交流比农村密切的多),因而可以通过收集不同城市的产业经济增长数据来分析验证上述有关知识溢出效应的增长理论。通过对中国31个省会城市及直辖市(不包括港澳台)1997~2006年10年间的城市-产业增长数据进行分析验证,得出结论:城市产业多样化促进创新思想的产生和知识溢出,进而促进了城市增长。
In the 1980s’, the theory of economic increase emphasized the stimulative functions on the technology, knowledge overflowing and exterior character of the human capital to the regional economic increase.The effects on the knowledge overflowing in cities were more remarkable than that in the towns, because in the cities, the information intercommunion was closer than in the towns.In this paper, the authors tried to testify the above-mentioned results at the theory of the regional economic increase through the data of the industry-economic increase in the different cities.So, the authors collected the data of the city-industry increase of 31 provincial cities in China from 1997 to 2006.Finally, the authors arrived the conclusions that it was the diversification of the industry not the specialization of the industry accelerated the innovate ideology and knowledge overflowing of the cities, and accordingly, it accelerated the economic increase of the cities.In other words, it is the ideology communication nearly brought the mostly innovate thoughts, and those innovate thoughts hoisted regional economic increase.According to the conclusion, we should change the research on the effects of the knowledge overflowing and source of the innovate thoughts from the industry’s inner structure to the ideology communication between each other in the departmental.
