ANALYSIS ON SPATIAL DISPARITIES OF PORT LOGISTICS ECONOMY AND EVOLVEMENT IN THE YANGTZE RIVER DELTA
研究了1990至2007年长三角14个集装箱港口物流经济的空间差异，发现总体差异逐渐增大，组间差异是主要贡献者，并分析了交通、通信、人力资源和产业组织等因素的影响。
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.
