Evaluation of Regional Carbon Neutrality Efficiency in China

Abstract

In the context of “3060 Carbon Neutrality”, there will be both theoretical and practical significance to finding out the status quo, laws and key factors about efficiency of carbon neutrality in various regions of China. This paper considers carbon neutrality system as a black-box combining “carbon absorption” with “carbon fixation”. According to these two major functions, we aim to measure efficiency of carbon neutrality among 30 provinces in China by constructing the three-stage DEA model. The results point that there exists obvious regional differentiation of efficiency distribution patterns; Key factors that determine the level of carbon neutralization efficiency mainly include spatial effects, industrial modernization, technological and innovative levels, and natural resources, etc. In summary, this paper provides suggestions and counter measures to promote carbon neutralization efficiency within various regions from two perspectives of regional low-carbon economy and regional linkage development.
