中国三大港口群的动态关系

Dynamic Relationship among Three Chinese Port Clusters

基于2005年第1季度至2013年第4季度的数据,利用脉冲相应函数对中国沿海三大港口群之间的动态联系进行实证分析。结果表明:三大港口群之间具有梯度的不对称的影响;从外溢角度来看,长三角港口群对珠三角港口群具有外溢作用,对环渤海港口群具有一定的外溢作用,但不是很明显;珠三角港口群和环渤海港口群的外溢作用均不明显;来自三大港口群的冲击均是对本港口群影响最明显,显示出"俱乐部效应"。

Pulse function is used to describe the dynamic relationship among the three major port clusters based on the data from 2005Q1 to 2013Q4. It is shown that the dynamic relationship is asymmetric. From the spillover aspect, the Yangtze River Delta port cluster is presented obviously overflowing effects on the Pearl River Delta port cluster and a little effects on the Bohai Bay Port Cluster. The Pearl River Delta port cluster is shown a little overflowing effects on the others such as the Bohai Bay port cluster as well.Influence on three major port clusters is carried obviously with ＂club effect＂.
