重庆市生产性服务业细分行业全要素生产率异质性及其影响因素研究

Research on the heterogeneity of TFP and its influencing factors in Chongqing's producer service sub-industry

采用DEA-Malmquist指数法,测算1998—2002年和2005—2014年重庆市生产性服务业及各细分行业全要素生产率(TFP)的增长变动情况,完成对生产性服务业细分行业间TFP异质性及其影响因素的分析。结果表明:研究期内重庆市生产性服务业呈粗放型增长,TFP总体表现为负增长,但增速逐渐减缓。TFP的两个主要构成要素技术效率和技术进步在2002年之前和2005年之后对TFP的影响存在差异,1998—2002年,技术效率对TFP起显著推动作用,技术进步的负向作用明显;2005—2014年,技术效率牵制了TFP的增长,技术进步对TFP的正向作用微弱。同时,生产性服务业细分行业的TFP和技术效率均表现出较大的行业异质性,技术进步的行业异质性最小;人力资本、创新投入和对外开放度对细分行业TFP异质性具有显著的负向促进作用,而政府规模的正向影响显著,工业化程度和信息化水平与TFP异质性无明显相关性。

By adopting DEA-Malmquist productivity index,this paper measures the growth rates of total factor productivity(TFP)in Chongqing's producer service and sub-industry in years 1998-2002 and 2005-2014,and analyses the heterogeneity of TFP and its influencing factors in producer service sub-industry.Empirical results show that Chongqing's producer service presents extensive growth,and as a whole the growth rate of TFP is negative but it is slowing down gradually.In years 1998-2002,the technical efficiency promoted the growth of TFP significantly but the technical progress acted as a negative stimulus to it.In years 2005-2014,the technical efficiency had a bad effect on the growth of TFP and technical progress’positive effect on it was getting weak.Meanwhile,the TFP and technical efficiency of the producer service sub-industry show greater industry heterogeneity,and the industry heterogeneity of technological progress is minimal.In addition,human capital,innovation input and the degree of openness have a significantly negative impact on the TFP heterogeneity of the sub-industry,and the size of government has a significantly positive impact on it,while there is no significant correlation between the level of industrialization and informatization,and TFP heterogeneity.
