国有企业改制政策效果的实证分析——基于双重差分模型的估计

The Evaluation of the Performance of SOE's Reform Policy

本文利用1999～2006年中国工业行业数据,通过构建双重差分模型(differences-in-differences),对始于20世纪末第三阶段国有企业改革绩效进行评估。结果发现,国有企业绩效虽仍有别于其他所有制类型的企业,但经济绩效自2003年前后发生明显好转,国有企业绩效已经与非国有经济较好的三资企业无差异。这表明,自1999年以来通过一系列改革措施,国有企业整体绩效获得了明显提高。同时,本文也间接揭示了国有企业规模、行业垄断地位以及国有经济战线的缩小对其绩效改善所起的积极作用。

This paper constructs differences - in- differences model using the official data on industrial finance and economic performance from 1999 to 2006 to evaluate the result of SOE＇s reform policy since 1999. Regarding our findings, although the performance of SOE has been worse than the one of private sectors, the performance of SOE has been improved step by step since 2003. All evidences prove that the policies suchas ＂seize the big and free the small＂, restructuring enterprises to corporation, and so forth, promote the reform of SOE and improve their own performance. Besides, this paper also finds the scale and monopoly of SOE play important role in the process of promoting economic performance.
