Spatial characteristics of the recent inter-provincial flow of social-economic elements in china
近期中国省际经济社会要素流动的空间特征

This paper reveals spatial characteristics of the recent inter provincial(municipal,regional) flow of social economic elements in China. Firstly, thepaper reviewsthe studies on the trans regional flow of social economic elements in China Then, based on the survey data,it conducts a comprehensive analysis of the spatial characteristics of the productive element flow such as the inter provincial migration, passenger railway flow, airborne passenger flow,railroad freight flow and information flow, by adopting GIS spatial analysis and visualization techniques. The spatial distribution of the inter provincial flow is influencedevidently by the provincial economic status and the pattern of inter provincial economic relations The eastern China shows its great importance on the distribution of the inter provincial flow The three economic heartlands of China, Jing Jin Tang (Beijing, Tianjin, Hebei), Hu Su Zhe (Shanghai, Jiangsu, Zhejiang) and Guangdong also act as the main centers of inter provincial flow The gravity centers of all the inter provincial flows are relatively close to the population and economic centers of China, but deviate far more from the geometric center of the territory This means the spatial distribution of inter provincial flow is basically consistent with the socialand economic situationof China Further, the paper concludes the spatialdistribution of the flow of social economic elements as four fundamental patterns, which are tested in each type of the flow and two holistic styles are deduced
