Spatial Evolution of Economic Pattern in“C-typed”Economic Region Along the Bohai Rim

Taking theC-typedeconomic region along the Bohai Rim as a study case, GDP per capita as the measuring indicator, this article used the methods of exploratory spatial data analysis(ESDA), semivariogram function, Kriging spatial interpolation and the software of Arc GIS10.0 and Geo DA to study the spatial evolution of economic pattern at the level of county in1990, 2000 and 2010. Then, driving factors of the spatial evolution of economic pattern were deeply discussed. Conclusions are drawn as follows: 1) At the overall spatial economic framework, the economic development ofC-typedeconomic region along the Bohai Rim shows a strong trend of spatial autocorrelation, and the patterns of high-high and low-low agglomeration are inclined to get strengthened continuously. The hotspots of economic development are centralized in the regions of Beijing-Tianjin-Tangshan Metropolitan Area, Shenyang-Dalian economic belt and Shandong Peninsula Urban Agglomerations, and the coldspots clusters in the inland and provincial boundary regions. The hotspot counties have been decreased remarkably, and coldspot counties are decreased first and increased afterward. 2) The economic growth also shows a strong trend of spatial autocorrelation, and the hotspot areas switch quickly, from scatter to concentration. The high values migrate to northwest of Liaoning Province, and low values center are on Beijing-Tianjin-Tangshan Metropolitan Area, middle and south of Hebei Province in 2000-2010. The economic disparities of inside province are decreasing, and the inter-provincial economic disparities are gradually increasing. 3) According to the space-time mechanism, the spatial economic framework ofC-typedeconomic region along the Bohai Rim tends to be more continuous and self-organized, and the random of the spatial differential pattern keeps decreasing, taking east coast as center. The homogeneousness of economic development in the east-west direction is typical for its relatively small spatial difference. As to the south-north, northeast-southwest and southeast-northwest direction, the spatial economic differences are great; and the radiation function of big cities obviously is weakening. Finally, 3 driving forces of economic framework evolvement inC-typedeconomic region along the Bohai Rim have been drawn: regional policies, economic and industrial foundation, location and traffic conditions. Generally speaking, the spatial evolution of economic pattern is complicate system engineering, and promoting the regional integration is also very long at the same time, therefore, some efforts should be made in the choices of index, methods and scale in the future.
