生产率分解下流通业内部结构演化及异质性研究

Internal Structure Evolution and Heterogeneity Analysis on Circulation Industry Based on TFP Decomposition

文章运用DEA-Malmquist指数法,在TFP分解视角下考察2004-2015年我国流通业内部结构演化及行业发展异质性。研究表明,我国流通业TFP增长的主导力量是技术进步,技术效率、规模效率及配置效率改进低下。流通业内部结构演化中各行业发展异质性特征明显,TFP及技术进步在各行业间异质程度呈微弱扩大趋势,技术效率及规模效率异质程度明显上升,配置效率差异程度有所下降。体制改革进程及信息技术资源配置是各行业异质化演化的主导机制。

This paper investigates the internal structure evolution and industrial heterogeneity based on the decomposition of TFP on circulation sub-industry with DEA-Malmquist productivity index method.The result shows that,the dominant factor of circulation industry TFP growth is technical progress;however,the overall levels of technical efficiency,scale efficiency and allocation efficiency change are low.The evolution of circulation industry demonstrates a strong heterogeneous pattern,and TFP and technical progress heterogeneity degree are slightly expanding.The technical efficiency and scale efficiency change shows a further expansion and the allocation efficiency difference is decreasing.The possible reason can be ascribed to the heterogeneity of circulation industry reform and the resource allocation of information technology.
