本文将SBM模型与四阶段DEA方法相结合，利用修正的四阶段DEA法，考虑松弛量对效率测度的影响，同时控制外部环境的影响，实证评估了2000-2006年14个OECD国家和中国的产险业经营效率。结果发现，各国环境外生变量，包括人均GDP、社会保障水平、金融深化程度、公司规模，对各国产险业的投入松弛程度有显著影响。在对环境因素进行调整后，各国产险业SBM效率上升明显，但在样本期间内没有呈现明显的逐年升高或者逐年下降的效率趋势。

This paper assesses the Slack-Based Measure （SBM） efficiency of nonlife insurance industry from year 2000 to 2006 in 14 OECD countries and China, using the modified four-stage data envelopment analysis combining slack-based- measure model and common four-stage data envelopment analysis. The new tech- nique takes account of the impact of slacks on efficiency measure, and incorporates environmental effects into performance evaluation based on data envelopment analy- sis. The results show that Environment {actors including GDP per head, social se- curity level, financial deepening and scale have significant effect on overall efficien- cy of individual countries.
