基于Malmquist指数的我国保险业生产力评价与实证分析

本文运用非参数的Malmquist指数法,研究了2000-2004年中国保险业的生产率水平及其动态变化,把Malmquist指数分解为技术变化和效率变化两部分。研究结果表明,我国保险业的Malmquist生产力指数逐年增长,其主要是由技术进步引致的,而不是来自效率的改善。从构成上看,存在着保险业技术进步和效率损失并存的格局。

The Empirical Analysis of Productivity of Insurance Industry of China Based on Malmquist Index Approach

This study uses nonparametric Malmquist procedures to investigate productivity level and its dynamics change in Chinese insurance over the period 2000 - 2004. Malmquist Index can be decomposed into two components, which is technical progress and efficiency change. The results of this study indicate that the Malmquist productivity index is increasing annually. The growth of productivity mainly stems from the function of the technological progress, not from efficiency improving. The decomposition result also shows that there was the coexistence improvement in technical change and retardation in efficiency change.
