The economic differences of provincial border-regions is a new research field of regional economic discrepancy. Based on comprehensive economic data of county level in Huaihai economic zone during the period of 1996-2005, using a global and local spatial autocorrelation, this paper carries out a preliminary exploration of the spatio-temporal pattern features, evolution trend and driving mechanism in this zone. The results are shown as follows. First, as for the counties similar at development level in Huaihai economic zone, the trend of polarization and congregation is consistent with evolution trend of economic diversity, which indicates that spatial polarization becomes the spatial structure evolution tendency in Huaihai economic zone. Second, during 1996-2003, the regional economic disparities in Huaihai economic zone, as well as inner economic disparities of the four regions, continue to expand with fluctuation, and the inner differences of Subei and Yudong regions are the main contributor to the changes in Huaihai economic zone. Since 2004, economic development disparity in Huaihai economic zone presents a slow expanding tendency, however, the inner economic differences of the four regions are obviously showing a east to west gradual expanding trend. Thirdly, H-H counties obviously concentrates to Lunan, and L-L counties obviously concentrates to Wanbei and Yudong. The result indicates that the economic diversity between the east and the west becomes the main token discrepancy of economy in Huaihai economic zone. Finally, the variation of the economic discrepancy in Huaihai economic zone is driven by many economic factors, such as investment ability, growth rate and industrial structure, as well as the influence of development policies of border-regions and the obstructing effect of provincial borders.
