摘要
作者根据第二次经济普查数据,研究了我国国有与非国有工业企业生产效率差异。OLS方法估计结果表明,国有与非国有工业企业生产效率差异从1995年的100%～400%,下降到2008年的17%～36%,随机前沿方法估计结果表明,国有与非国有工业企业技术无效率差异从1995年的22%～57%,下降到2008年的9%～21%,且国有工业企业技术效率仅比非国有工业企业低2.1%～6.3%,这表明国有工业企业的生产效率得到了大幅度提高,但国有企业生产效率的提高主要依赖其规模和垄断优势,在竞争性行业国有工业企业生产效率仍然低于非国有工业企业10%以上。
Based on 2008 China Economic Census data,this paper analyzes the difference of productive efficiency between stateowned（SOE） and non-state-owned（NSOE） enterprises.OLS estimation shows that the difference of productive efficiency between SOE and NSOE decreases from 100%~400% in 1995 to 17%~36% in 2008.Stochastic Frontier estimation shows that the difference of technology inefficiency between SOE and NSOE decreases from 22%~57% in 1995 to 9%~21%,and the difference of technology efficiency is between 2.1% and 6.3%.Hence,the productive efficiency of SOE has been improved remarkably.But the scale expansion and monopolization may mainly account for such a change.The productive efficiency of SOE is still 10% lower than that of NSOE in competition industry.
