Research On Economic Spatial Differentiation And Optimization Of The Yangtze River Economic Belt Based On GIS-ESDA

Differentiation of regional economic space has attracted wide attention of scholars at home and abroad, the research on regional economic spatial differentiation in the minority, but the lack of comprehensive and systematic study. Differentiation pattern and law of the Yangtze River Economic Belt economic space, to promote the sustainable development of the Yangtze River economic belt, and promote the coordinated development of the regional economy has important significance. In this paper, the mainland city of the Yangtze River economic belt as the research object, from the economic spatial differentiation trend and economic space is divided into two aspects of mechanism, and the Yangtze River Economic Belt economic spatial differentiation were analyzed by various methods.This paper focuses on the following two problems, one is the Yangtze River Economic Belt economic spatial differentiation trend, two is the Yangtze River Economic Belt economic spatial differentiation mechanism. The state and process of summary recognition research on economic spatial differentiation trend mainly includes the calculation, spatial organization pattern differentiation degree and spatial differentiation. Study on the differentiation mechanism of economic space mainly from the basic theory, factors affecting the extraction of the Yangtze River Economic Belt economic spatial difference, and with the help of the model for empirical analysis in Geoda software.This study obtained the following conclusions. The differentiation trend in the economic space, first, the differential degree of economic space showed a declining trend of economic spatial difference gradually easing, but the differentiation degree is still high. Second, the eastern region is dominated by the high level and high level of economic growth in the Midwest region, low level and low level of growth type, east to west, showing the economic level from high to low gradient distribution. Third, Shanghai, South of Jiangsu and Zhejiang area growth in the eastern region of the main play diffusion effect, growth in the central and western regions in Chongqing city and Guiyang city as the representative of the main pole play a gathering effect, the eastern and western growth pole number obvious gap. Fourth, the economic space organization eastern region dominated by multi core edge structure and network structure, the economic spatial organization in central and western regions dominated by the core periphery structure and point axis structure. In the economic spatial differentiation mechanism, spatial lag model regression showed that the regression coefficient of each factor of labor, capital, financial expenditure, industrial, transportation, towns were all positive, and in the 5% level of significance is significant, the economic meaning for each influence factor on economic growth have a positive role.This paper tries to analyze the beneficial in the economic spatial economic situation and spatial differentiation mechanism of river basin can also be applied to other related research on regional economic spatial difference.
