摘要
利用Malmquist-Luenberger指数对中国2004~2017年服务业细分行业绿色全要素生产率指数进行测算;根据Dagum基尼系数及分解方法对服务业绿色全要素生产率增长的行业差异及来源进行分解,同时利用多种方法对其收敛性进行检验。研究发现:环境约束下不同服务行业绿色全要素生产率指数的变动不同,信息传输、计算机服务和软件业等7个行业表现出环境友好的属性,绿色全要素生产率的增长主要来自技术进步;近年来服务业绿色全要素生产率增长的行业差异在缩小,行业间差异是服务业绿色全要素生产率增长行业差异的主要来源;服务业各行业的绿色全要素生产率增长没有呈现明显的σ收敛特征,但均存在显著的绝对β收敛和条件β收敛特征,生产性服务业的收敛速度最慢。
This paper calculate the green total factor productivity index of all service sectors in China from 2004 to 2017 by the Malmquist-Luenberger index. And then, it decomposes the sector differences and sources of green TFP growth in service industry according to Dagum Gini coefficient and decomposition method. Result shows that seven industries, including information transmission, computer service and software sector, show environment-friendly attributes, and the growth of green TFP mainly comes from technological progress. In recent years, the sector differences of green TFP in service industry show a downward trend, and the main differences comes from the inter-sector differences. There is no obvious σ convergence in green TFP growth in service industries. However, there are significant absolute β convergence and β conditional convergence. Among them, producer service sectors have the slowest convergence rate.
