Analysis Of Regional Economic Time-space Patterns Of Gansu Province Based On GIS

Spatial pattern of regional economy, as the regional economy spatial distribution form, is the result of the implementation of the different development strategy based on regional specified natural and social factors. Since the reform and opening up, especially in the 21st century, Fujian Province has made considerable social and economic development. At the same time, the differences of economy between regions have been prominently increased, and its structure has also became gradually clear. Based on relevant domestic and foreign researches, this paper analyzes the regional economic pattern of space-time evolution characteristics, the formation process, dynamic mechanism in detail from the heterogeneity structure and spatial dependence of regional economy in Fujian, respectively by the method of empirical analysis and GIS spatial.Research shows that the regional economy gradually showing a pattern of "core-edge+axis ", which are the maincoastal economic growth axis along Fuxia Highspeed Road centered on Fuzhou, Quanzhou, Xiamen, the secondary inland economic growth axis along Yingxia Railway centered on Sanming, Longyan, and the edge area standing by backward region such as Nanping, Ningde, Zhangzhou.The results of GIS spatial analysis show that the economically developed coastal areas, such as Fuzhou, Xiamen and Quanzhou, are increasing the absolute gap between inland area, while the west area, such as Longyan and Nanping, are narrowing the relative gap by its advantage. The regional economic has not only the heterogeneity, but also the spatial dependence. Based on different spatial weight matrix, the spatial autocorrelation analysis method explores the correlation of regional economic in Fujian Province, which shows association of the whole economy has low connection, but local economy has a strong relevance.Besides, where is near Xiamen in the southeast has formed a high value accumulation area, whilewhere is around Nanpingand Ningde in the northwest has formed the low value accumulation area.In order to investigate the formation of regional economic spatial pattern of the internal mechanism of Fujian Province, multiple factors that effect on the entire province regional economic spatial heterogeneity and dependence are compared by geographically weighted regression model and space-time geographically weighted regression model. It can be concluded that the industrial structure, transportation facilities, fixed investment, urbanization are the major factors affecting the development of regional economy in Fujian Province. These factors in different time determines the entire province economic spatial distribution form to different degree.
