国有工业企业生产率的区域性差异及收敛性检验——基于贝叶斯SFA共同边界方法

Regional Differences of State-owned Industrial Enterprises Productivity and Convergence:Based on Bayesian SFA Metafrontier

基于1999—2010年中国地区国有工业企业面板数据,应用贝叶斯SFA共同边界方法对地区国有工业企业Malmquist生产率指数进行测算,并检验其收敛性。结果显示:国有工业企业生产率的增长是伴随着国有企业改革的深化而出现的,但这种增长主要是由于技术进步所引起,国有经济内外部软环境实力的提高并不显著;从地区差异来看,中国中部地区在国有经济生产率增长速度以及技术进步速度方面最快,其数值指标要优于东部及西部地区。收敛性分析结果显示,中国地区国有经济生产率并没有出现全局性随机收敛特征。而从各地区群组来看,只有东部群组存在俱乐部收敛,而中、西部群组不存在俱乐部收敛效应。

Based on state-owned industrial enterprises panel data in 1999-2010, the paper applies Bayesian SFA Metafrontier to estimate Malmquist productivity index of those enterprises in China, and test its convergence. The results show that China′s state-owned economic productivity growth is mainly caused by technological progress, but the improvement of management level and the soft environment is not significant. Regionally, China′s central region is better than the eastern region and the western region in both productivity growth rate and the speed of technological progress. The convergence analysis show that Chinese state-owned economic productivity do not appear overall random convergence characteristics. From a regional perspective, only the eastern group exists club convergence, while the central and western groups do not exist club convergence effect.
