我国物流业全要素生产率的动态演化——基于DEA的Malmquist指数的实证分析

Dynamic Evolution of Total Factor Productivity of Chinese Logistics Industry: An Empirical Analysis Based on DEA-Malmquist Index

首先利用非参数的DEA-Malmquist生产率指数方法对1995-2007年中国物流业全要素生产率(TFP)的变动进行测度,并对TFP指数进了分解。研究结果表明:(1)我国物流业生产率总体上处于增长趋势,并呈现先增长后下降再增长的特征;(2)技术进步是物流业生产率增长的关键因素,而技术效率是物流业生产率改善的瓶颈。

The paper first measures the change in the total factor productivity of the Chinese logistics industry between 1995 and 2007 using the non-parametric DEA-Malmquist index and decomposes the TFP index into several components. The finding indicates that the overall trend of the productivity of the Chinese logistics industry is growth, more specifically growth followed by contraction and again followed by growth; techni- cal advance is the key factor driving the growth of the productivity of the industry while technical efficiency is the bottleneck in this regard.
