中国省区全要素生产率的随机收敛性--基于Malmquist指数法

Stochastic Convergence of China’s Provincial total Factor Productivity--Based on Malmquist Index Method

本文基于Malmquist指数法测算了中国31个省级行政区的全要素生产率,并研究了省区之间全要素生产率的随机收敛性。结果发现31个地区中有22个体现了随机收敛性,而天津、内蒙古、辽宁、安徽、江西、湖南、海南、云南、青海9个地区是发散的。同时,将全要素生产率分解成技术效率变动和技术水平变动,对发散地区的技术效率变动和技术变动分别进行随机收敛检验。结果显示,由于技术效率发散引起全要素生产率发散的地区有安徽、江西、云南;由于技术水平发散引起全要素生产率发散的地区有辽宁、江西。根据发散的原因不同,建议采取不同的政策以提高全要素生产率。

Based on Malmquist index method,this paper estimates the TFP of 31 provinces in China,and studies the stochastic convergence of TFP between provinces.The results show that 22 of the 31 regions reflect the random convergence,while the 9 regions of Tianjin,Inner Mongolia,Liaoning,Anhui,Jiangxi,Hunan,Hainan,Yunnan and Qinghai are divergent.At the same time,the total factor productivity is decomposed into technical efficiency change and technical level change,and the random convergence test is carried out on the technical efficiency change and technical level change in divergent areas.The results show that Anhui,Jiangxi and Yunnan are the regions that cause the divergence of TFP due to the divergence of technical efficiency;Liaoning and Jiangxi are the regions that cause the divergence of TFP due to the divergence of technical level.According to the different reasons of divergence,it is suggested to adopt different policies to improve TFP.
