Comparative Study of OFDI Efficiency in China Based on SBM-Model

Abstract

Since the “Belt&Road” was put forward, China has always been committed to building a green the “Belt&Road”. Based on the panel data of China s direct investment in 30 key countries along the “Belt&Road” from 2009 to 2018, this paper systematically analyzes the efficiency of green investment from multiple dimensions by using SBM-undesirable model. The research shows that the efficiency of China s green investment in countries along the “Belt&Road” is generally good, but there are big internal differences among the host countries. In recent years, the rising pure technical efficiency of green investment has largely compensated for the relatively low scale efficiency of green investment. The research in this paper provides evidence for understanding the relationship between China s the belt and road initiative initiative and the green sustainable development of the host country, and provides theoretical support for countries to create a harmonious international investment environment.
