我国生产性服务业全要素生产率的异质性及收敛性分析

Research on the Heterogeneity and Convergence of Total Factor Productivity in Chinese Producer Service

运用Malmquist生产率指数方法，从产业、时期和地区三个角度分析了2004～2011年我国生产性服务业全要素生产率的异质性，并对其趋势进行了收敛性检验。结果表明：我国生产性服务业的总体TFP年均下降1．9％；受技术进步效率的影响较大，呈收敛趋势，收敛速度为年均17．3％，2008年以后，收敛速度加快；各细分产业TFP的趋势和原因有所不同，产业间存在有收敛，产业内都存在显著的绝对B收敛，批发和零售业的收敛速度最快；多数地区生产性服务业的效率不高，差异较大；生产性服务业及其细分产业、东部与西部地区生产性服务业的TFP随着时间推移，将向各自的稳态水平趋同。

Based on methods of Malmquist productivity index, an analysis is made on the heterogeneity and the convergence of total factor productivity in Chinese producer service during 2004 to 2011 from the perspectives of industry, period and district. The results show that： affected by technology advancement mainly, the total factor productivity in Chinese producer service decreases by an average of 1.9% annually. It presents a convergent tendency. The convergence speed is 17.3% annually, and it accelerates after 2008. The trends and causes of the TFP in sub-industries of Chinese producer service are different. There are significant σ convergence tendency between subndustries and absolute 13 convergence tendency in sub-industries of Chinese producer service, and the convergence speed of the TFP of producer service in the wholesale and retail industry is the fastest. The TFP in most districts are not high, and show significant variations. The gaps of TFP in Chinese producer service and its sub-industries, the producer service in eastern and western areas of China are gradually narrowing, and will converge to their steady-state equilibrium respectively.
