Research on technological efficiency of ecological ports in China based on network approach

Abstract

According to the sustainable development of Chinese ecological ports, a set of index evaluating the technological efficiency of ecological ports is forwarded in the beginning, to compensate the deficiency in index selection and the lack of statistical and quantitative studies in current related researches. In the following an appraisal model of ecological port technological efficiency is formulated based on network approach, to facilitate the evaluation of ecological port technological efficiency and the identification of major affecting factors. Empirical study is conducted on eight principal ecological ports in China including Dalian etc. Technological efficiency of each ecological port is calculated and scored. And affecting factors are identified and analyzed. Suggestions on how to improve the technological efficiency in Chinese ecological ports are given in the end.
