中国服务业技术效率的系统性分析

本文利用随机前沿分析法研究后发现,从行业层面看,管制松的行业技术效率比管制紧、进入壁垒高的服务行业高,技术效率由东部向中西部呈递减,各地区存在行业分布的结构性差异;2004-2009年的服务业技术效率先小幅上升后下降,而且有些行业具有抗外界经济波动冲击的特性。从上市公司层面看,进入壁垒越高,行业技术效率越高,民营企业技术效率低于国有或集体所有制企业。通过对比发现,这很有可能是管制引起的,高进入壁垒给在位垄断企业带来了好处,但导致了行业内部的发展不平衡。

Analysis on Production Efficiency of China’s Service Sectors

This paper analyses features of the production efficiency of China’s service sectors from 2004 to 2009 at listed-company and sector level.At the sector level,empirical evidence shows: 1) the technical efficiency of regulated sectors is lower than that of less-regulated sectors.2) the technical efficiency of service sectors decreases gradually from the east to the west,and there exists distributional difference among various regions.3) the technical efficiency rises first slightly then falls down.The dynamic change of each sector shows that some sectors can resist external economic fluctuations.At the listed-company level,empirical evidence shows the technical efficiency rises with the higher entry barrier,and the technical affiance of private companies is lower than that of state-owned or collective companies.Comparing the results from two angles,we have found that regulation causes such imbalance and distorts the development of the entire sector.
