spatial-temporal pattern and spatial interaction types of economic disparities of county level in Huaihai Economic Region during 1995-2006 have been preliminarily probed into by the method of combining EDSA and Statistic analysis.The study is done on the base of county level and is measured by the index of per capita GDP.The following conclusions are found.The total economic disparities of county level in Huaihai Economic Zone have enlarged.The integral economic disparities of county level in Huaihai Economic Region are bred by the disparity among North Jiangsu, South Shandong, East Henan and North Anhui and the disparities inside North Jiangsu Province and inside South Shandong Province.The counties with high economic level have extended along the direction of main traffic lines.Three economic developing axles have shaped including Beijing-Shanghai Railway (Tai’an-Xuzhou ), Yanzhou-Rizhao Railway and along the coast.The counties with low economic level have shaped an undeveloped corridor along Beijing-Jiulong Railway.The low-level and low-growth poverty trap assemble areas have appeared in the boundary of Henan Province and Anhui Province.According to the relationship between the county and the adjacent county, the counties in Huaihai Economic Region can be divided into the diffuse pattern, polarization pattern,‘sinking’pattern and‘infection’pattern.
