摘　　要：以县域为研究单元，以人均GDP为测度指标，利用EDSA与统计分析的方法，对1995—2006年淮海经济区县域经济差异的时空格局及空间作用类型进行了初步探索。结果表明：淮海经济区县域经济总体差异呈扩大趋势，苏北、鲁南、豫东、皖北4地区之间的差异以及苏北内部、鲁南内部差异是淮海经济区整体差异的主要贡献者；高水平县域沿主要交通线方向扩展，形成沿京沪线（泰安-徐州段）、兖石线、沿海3条经济发展轴；低水平县域沿京九线形成不发达走廊，并在豫皖边界地区出现低水平-低增长并陷入贫困陷阱的集聚区；根据县域与相邻县域的关系，将淮海经济区县域分为扩散型、极化型、“沉陷”型、“传染”型。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 level have shaped -Xuzhou ）, Yanzhou -Rizhao Railway and along the coast. The counties with low economic 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 .
