港口基础设施、港口效率与城市贸易发展——基于中国主要港口的经验分析

Port Infrastructure, Port Efficiency and City’s Trade Development: Evidence from China’s Major Ports

本文首先考察了中国港口基础设施建设水平,并使用DEA方法测算了港口效率的现状,随后以中国25个主要沿海港口及其所在城市的相关数据,实证检验港口基础设施建设对港口所在城市贸易发展的影响。实证结果表明,港口货物吞吐量、泊位数量、码头长度等港口基础设施水平的提高能够促进贸易发展;港口效率对北方港口城市的贸易发展具有显著的促进作用;更大的市场规模、更高的消费物价水平、更多的外资利用以及更发达的第二产业往往会促进城市贸易发展。

This paper attempts to explore the status quo of China's port infrastructure and port efficiency, and to explore the relationship between trade and the level of port infrastructure construction. From the data of 25 Chinese major ports, we obtain the following conclusion. The improvement of the level of port infrastructure can promote the development of trade. The influence of port efficiency on trade is only significant for northern ports. Generally, greater market size, higher consumer price levels, more foreign investment, and a more developed secondary industry will contribute to the development of the city's trade.
