江苏省各区域经济发展差距的实证分析

An Empirical Study on the Gap in Economic Development of Districts in Jiangsu

文章运用测度经济发展均衡程度的新指标——余期望系数,测度了江苏三个区域和各自内部城市之间2000—2005年经济发展差距。据此,结合其它指标,文章分析出:一是支撑江苏非均衡发展的主要动力来源于投资拉动而非效益提高,二是江苏收入分配状况随经济发展过程而变化的关系总体符合库兹涅茨"倒U假说",苏中、苏北的倒U曲线处于上升阶段,而苏南的倒U曲线已接近拐点。

The writer uses a new index called; Surplus-expectation coefficient to measure the gap covered 2000 to 2005 in economic development of districts in Jiangsu. By this means, the paper point out that the main power sustaining the non-equilibrium development of districts in Jiangsu comes from investment not efficiency and the degree on income diversity of employees with economic development answers for ＂Simon kuznets inverted U curve＂.
