生产性服务业细分行业TFP变动的测度与异质性研究:以重庆为例

Study on Measure and Heterogeneity of TFP's Change of Sub-Classification Producer Services Industry:An Emperical Analysis Based on Chongqing

在界定生产性服务业概念的基础上,利用重庆市二次经济普查后的修订数据,运用DEA-Malmquist生产率指数法测算了1998-2012年重庆市生产性服务业细分行业TFP、技术进步与技术效率.结果显示:1998-2002年的生产性服务业TFP呈下降趋势,2005-2012年呈上升趋势;生产性服务业发展已经开始由粗放型发展方式向集约型发展方式进行转变,与服务业对比,生产性服务业已不再是使服务业效率低下的主要因素;生产性服务业细分行业TFP变动具有较大行业异质性,这种异质性主要是由技术效率变动不同引起的.

On the basis of defining the concept of “producer services industry” ,we use the revised data of Chongqing after the second economic census to estimate the T FP (total factor productivity ) ,technical progress and pure technical efficiency of the producer services industry segments of Chongqing in 1998 -2012 ,using the DEA‐Malmquist productivity index method .The results show that the TFP of producer services declined in 1998-2002 and was on a rise in 2005-2012 ,that the development of producer services experienced a change from the extensive pattern to the intensive pattern ,and producer services were no longer the main contributing factor to the declining efficiency of the service industry ,and that T FP change of producer services sub‐classification had a considerably large industry heterogeneity which was owed to the different changes of technical efficiency .
