我国沿海主要规模以上港口投资效率研究——基于DEA和Malmquist指数

Evaluating the Investment Efficiency of Major Coastal Ports in China——Based on DEA Model and Malmquist Index

港口对于未来经济的发展发挥着重要的作用,"港城融合"是未来的发展趋势,也是促进经济腹地发展的重要因素。因而,沿海港口的投资效率备受瞩目。采用DEA和Malmquist指数方法,对我国沿海主要规模以上港口的投资效率进行静态、动态剖析,发现:我国沿海主要规模以上港口的投资效率为非DEA有效,其无效率主要是来自规模和技术两个方面,并且60%沿海港口的综合技术效率低于0.5;其全要素生产率年平均增长6.3%,主要的促进因素是技术进步。可见其投资效率迫切需要改进,并针对其存在的问题提出有效的改进建议。

Port plays an important role in the development of the future economy, and the future development trend is ＂harbor city fusion＂, which is the important factor to promote the development of economic hinterland. Therefore, investment efficiency of coastal ports is being concerned. This paper makes the static and dynamic analysis to the investment efficiency based on DEA and Malmquist index method, finding that the investment efficiency of China＇s major coastal ports is the DEA ineffective, the reasons lie in scale and technology, and 60% of coastal ports comprehensive technical efficiency is lower than 0.5, and the catalyst of total factor productivity is the technical progress, and achieve the average annual growth of 6. 3%. Hence the investment efficiency is urgent to improve, and in allusion to the problem, effective suggestions for improvement are put forward.
