Abstract:

Based on spatial autocorrelation theory and economic gravity model, using the method of spatial statistics analysis, we collected the economic indicators such as per capita GDP, total import and export, and capital actually used of foreign direct investment (FDI) in Henan by foreign countires, as well as Hong Kong, Macao and Taiwan. Further, this paper analyzed the spatial and temporal evolution trajectories of economic spatial structure in Henan Province. The conclusions were as follows: (1) There was an economic link among each city. Zhengzhou, as the economic center of Henan, had a positive impact on the economic development of the surrounding cities. The economic links among cities were weak in southeastern Henan. Therefore, the economic spatial structure of the province showed a typical "Core-Peripheral" feature. (2) Per capita GDP of each city presents strong spatial autocorrelation. Cities in central-western Henan had become a region of high-level economic agglomeration, while eastern Henan was generally lower than the province's average of economic development. (3) Within the study area, the economic growth showed a certain degree of stability in the process of the spatial agglomeration. The process of urban economic agglomeration showed a good consistency with the evolution trend of GDP per capita and FDI. Finally, the spatial and temporal evolution of the economic spatial structure of Henan province is closely related to the economic policies that have been released by the government.
