Differences and the convergence in the regional economy are the current hot spots in academic research. However, the research involves relatively few fields associated to the industrial economy. According to this, this paper divides Jiangsu province into three regions, and with this regional setting and the method of quantitative analysis, the paper selects some relevant indicators about the industrial economy in Jiangsu Province at county level from 1980 to 2007. Then the paper uses the Theil index and β convergence test to analyze the difference and the convergence of industrial economy in Jiangsu province in different periods and different areas. Finally, the main reasons leading to the convergence are discussed based on the above calculation results. The main conclusions are drawn as follows. Firstly, there is convergence both in the three areas and among areas. But with the elapse of time, the speed of convergence shows a downward trend. Then the dimension of industrial difference among areas fluctuates up and down, however it also keeps increasing in the fluctuations with the time on a whole. And the industrial economy difference among areas dominates the whole province. Secondly, the dimension of industrial difference in areas reaches the maximum in southern Jiangsu and the minimum in northern Jiangsu. From the results, at the same time, we can find the speed of industrial economy convergence in Jiangsu is getting slower and slower when the economy develops. We can also see that developed areas have faster speed of convergence, while less developed regions have slower speed of convergence. Besides, differences and convergence of industrial economy are mainly due to the changing conditions of industrial structure, newly increased fixed assets, talents and technology, transportation volume, etc. Although the industrial economy differences has become lower and lower and there is convergence among areas, the industrial economy differences will not be eliminated in a long period of time.
