港口建设对区域经济技术效率的影响研究

沿海港口建设作为基础设施领域的重要投资,对区域经济发展起着直接和间接的作用.为了考察港口建设与区域经济技术效率之间的关系,本文采用随机前沿分析方法,将港口建设投资作为模型中技术无效项的核心解释变量,通过实证分析表明,我国沿海港口建设投资对区域经济技术效率的提升具有显著的正向作用,而且不同时段、不同地区的港口建设对区域经济技术效率的影响存在明显差别.在港口建设规划与政策制定过程中,应将区域经济技术效率因素和不同港口群之间的发展差异特征考虑在内.

The Impact of Seaport Investment on Technical Efficiency of Regional Economic Growth

As the important infrastructure investment, the construction of seaport plays a direct or indirect role in the development of regional economy. To explore the relationship between the scale of seaport construction and the efficiency of regional economic development, Stochastic Frontier Analysis is employed in this paper, in which the investment of seaport construction is set as the core variable of technical inefficiency item in the related model. The empirical results show that seaport investment has a positive effect on the improvement of technical efficiency in regional economy. Moreover, port construction in different periods and regions have different influences on technical efficiency of regional economy. It concludes that technical efficiency of regional economy and developmental difference of port groups should be taken into account in the process of port construction programming and policy-making.
