Analysis of Growth Differences and Convergence of Regional Green TFP in China

By entropy method,this paper constructs a comprehensive environment pollution index taken as nonideal economic output and incorporates this index into nonparametric DEAMalmquist model.Then it measures the green Malmquist productivity indexes of 29 provinces in China from 1995 to 2008,and analyzes the impacts of green Malmquist index,technological efficiency,the rate of technological progress on the disparity of regional economic growth and its trend over time.The results show as follows: firstly,during the sample period,the environmental pollution in China is worsening;secondly,the growth rate of TFP significantly decreases with the consideration of environmental pollution,and the difference of technological progress is the main reason for the disparity of regional economic growth;thirdly,on the whole,there is not absolute convergence of green Malmquist index,and only the green Malmquist index in eastern region is featured by typical club convergence;fourthly,after the control of investment rate,the growth rate of employees and environmental governance,there is conditional convergence in all regions.
