中国生产性服务业细分行业全要素生产率异质性与影响因素研究

Research on the Heterogeneity and Influencing Factors of Total Factor Productivity in China's Producer Service Sub-industry

笔者运用Malmquist-DEA指数法测算了中国生产性服务业细分行业TFP增长变动情况,并对行业异质性和影响因素进行了分析。结果表明:研究期内TFP均呈增长趋势,并表现较大的行业异质性,但各指数的差异程度没有明显的趋同或扩大趋势。1991年～2002年,TFP增长的主要动力源自技术效率和技术进步共同作用,2003年之后,则主要依靠技术进步提高。另外,除市场开放度对TFP增长起负面影响外,创新投入、消费需求、工业化程度等因素均具有显著的正面促进作用。

With the Malmquist productivity index of DEA model, this paper measures the growth rates of total factor productivity （TFP） in China＇ s producer service sub-industry, and analyses the heterogeneity in its sub-industry and influencing factors of the TFP. Empirical results suggest that producer services TFP in overall level and sub-industry level appear all increasing trend, and demon- strates strong heterogeneous pattern, while it is not obviously converging or expanding to the difference in pitch of all the indicators. The dominant factors leading to TFP growth are combined effects of technical efficiency improvements and technological progress during 1991 -2002, and technological progress after 2003. Moreover, the influencing factors such as RD,CON and INDUS act as a positive stimulus to the growth of TFP, except for the factor of OPEN.
