Spatial Concentration and Specialization of Large-Scale Commodity Exchange Markets in China under Multi-spatial Scales

Along with the rapid development of Chinese economy, the spatial distribution pattern and specialization level of commodity exchange markets changes greatly. According to analysis on large scale commodity exchange markets (LSCEM) of China from 2000 to 2005 under multi-spatial scales, the authors draw the following conclusions: the spatial concentration degree of LSCEM which develops based on particular geographical environments and natural resources is related with market types, which developed based upon the particular geographical environments and natural resources possess relatively high and steady degree of spatial concentration which developed ground on the high tech and advanced industries have relatively low degree of spatial concentration at zonal level and relatively high degree of spatial concentration at provincial level; which developed found on the popular consumption demand are provided with rather low degree of spatial concentration at various of spatial levels. Meanwhile, LSCEM incline to centralize in the eastern coastal areas of China and big cities. Their specialization indexes are high at the provincial level, however, drop on the whole. The statistical regression analysis shows that the urbanization level, Engel coefficient and market development degree have fairly notable impact on the specialization of LSCEM, but the industrial concentration level, private economy development level and the net income of urban residents have no significant effect on the specialization of LSCEM, and the trade competitiveness index has extremely little impact on it.
