摘要 采用改进的SBM方向性距离函数和共同前沿Malmquist-Luenberger(MML)生产率指数,对2004—2016年中国30个省份的服务业绿色全要素生产率(TFP)进行了再测算,并考察了其空间收敛性。研究结果表明:中国服务业绿色TFP呈现上升趋势,绿色技术进步是其变动中的主导因素,而绿色技术效率和技术缺口比率的贡献为负;服务业绿色TFP增长呈现出较明显的区域和省际异质性,在考虑空间效应的情况下,中国服务业绿色TFP同时存在绝对β收敛和条件β收敛,且收敛速度加快,这主要归因于绿色技术进步的空间收敛,而服务业绿色TFP的收敛特征呈现出明显的区域异质性。 This paper applied modified SBM directional distance function and metafrontier Malmquist-Luenberger(MML)productivity index to recalculate the green total factor productivity(TFP)of the service industry of China's 30 provinces from 2004 to 2016,and empirically studied the spatial convergence of the green TFP.The empirical results showed that,the green TFP in China's service industry showed an upward trend,which was mainly driven by green technical change,and the contributions of green efficiency change and technical ratio gap change to the green TFP growth were negative.Meanwhile,the green TFP growth in China's service industry demonstrated significant regional and interprovincial disparities.After considering spatial spillover effects,the green TFP in the service industry of China had both absoluteβconvergence and conditionalβconvergence,and the rate of convergence rose,which was mainly attributed to the spatial convergence of green technical change.And the convergence of green TFP in the service industry showed significant regional heterogeneity.
