国有企业改制效果的实证研究

本文通过对1998至2003年间全部国有企业和规模以上非国有企业的数据进行分析来研究我国国有企业改制的效果。我们不仅考察了改制对企业经济效益的影响,而且考察了改制对企业社会效益指标的影响。此外,我们还分析了改制影响经济效益的渠道、国有控股和非国有控股的差别、以及改制效果的可持续性。本文的主要发现是:改制后企业经济效益显著提高,并且主要来自于代理成本的降低,表现为管理费用率的下降;改制带来了一定的社会成本,但和国际经验相比程度不是很大;国有控股改制社会效益较好,而非国有控股改制经济效益较好;改制效果在一定期间内持续。

An Empirical Study on the Effects of Ownership Reform in China

Using a comprehensive panel data set of China's state-owned enterprises, we investigate the impacts of ownership reform and different extent of non-state ownership on social welfare and firm performance. We also consider the sources of the gain in firm performance and the long-run impacts of ownership reform. It is found that ownership reform improves firm performance mainly through reducing managerial expenses, and the social costs of ownership reform are limited compared to international experiences.
