中文摘要：

以长三角14个集装箱港口为基本研究单元,选用塞尔指数对该区域近18年的港口物流经济发展进行了定量测度。结果表明：①区域港口物流经济发展整体差异不断扩大,但表现出一定的波动性,其中1990—1993年、1999—2001年及2004—2007年三个时段的发展差异逐步缩小;②基于不同分组的组内、组间发展差异明显,但组间差异一直是导致港口物流经济发展总差异演变的重要原因;③交通区位优化、相关产业及发展政策、信息与人力资源状况以及航运网络优化等是导致上述动态特征的成因机制。

英文摘要：

This paper takes 14 container port logistics economy in the Yangtze River Delta as basic study units and takes output value of container port per GDP as an index for measuring port logistics spatial economic disparities. Then we use Theil index as quantitative methods to demonstrate the level of port logistics economy from 1990 to 2007. By calculating the concerned statistics,that there are there obvious features：①from 1990 to 2007,the total port logistics economy spatial disparity increases gradually with fluctuations appearing in several years. ② The inter-group spatial disparities mainly devote to the overall disparities and its Theil index is increasing. ③The paper holds that the following factors have profound implications on it：the change of regional transport superiority,level of telecommunication and human resource,the development of industry and spatial organization networks of container transportation.
