| The space is the essential characteristics of regional economics difference from other economic disciplines of the factors of production, region and economic development level. Industrial structure type synthesis in the projection space form the regional economic spatial structure is important. The spatial structure of regional economy has its own change. A tremendous impact on the development of regional economy has the close relation with the area, so it is significant to study the spatial structure of regional economy connotation and optimization mechanism. Since the long term, the economic spatial structure is always an important research content of regional economics, city economics and other related disciplines. The spatial distribution of regional economic disparity and convergence problem is an important breakthrough in the study of regional economic development and export of difference analysis, spatial distribution can reveal the evolution process and the status quo, on the convergence analysis can reveal the trend of its development. In this paper, through the analysis of the counties of Jiangsu province spatial econometrics using measuring software, to a certain extent, the theory of regional economic spatial structure combined with the practice, the specific economic spatial structure optimization put forward their own views.Based on reading literature, this thesis the spatial correlation using spatial statistical method from two aspects of global and local counties and cities of Jiangsu per capita GDP, respectively from the global spatial autocorrelation and local area from two aspects of correlation analysis of auto correlation and the county of Jiangsu province (city, area of whole space) spatial autocorrelation is significant inter domain, and the type and classify the results, presented through a form of visual chart, so as to observe the model of agglomeration economic development level of Jiangsu Province in the space and its changes with time. Secondly, the theoretical and empirical model was constructed to examine spatial spillover effect of regional economic growth, and spatial econometric analysis.The results show that:(1) There are economic development differences in three regions of Jiangsu province, and from the development of Jiangsu province economy to do correlation analysis results, that is to say, the Jiangsu Province as a whole, the unit of space economic development level is positively correlated with each other significantly, and shows the correlation between regions tend to close. (2) The study found that, the regional economic disparity of Jiangsu Province is not blindly expand after the reform and opening up. After a period of expansion, the regional economy of Jiangsu began to have a trend of convergence. This shows that the Jiangsu province region economy has turned the corner of the inverted U curve, entered the inflection point on the right side. |
