Research on efficiency evaluation of China's coastal ports based on DEA-SBM model and GTFP index

Abstract

In order to study the development efficiency of China's coastal ports, combined with data envelopment analysis model (DEA-SBM) and green total factor productivity GTFP index, this paper systematically evaluates the green development efficiency of China's coastal ports from 2014 to 2019. The results show that: the production efficiency of China's main coastal ports has been improved to varying degrees;Technological progress is the main driving force affecting the efficiency of port green development. According to the research results, the corresponding development countermeasures are put forward to promote the development of green ports in China.
