我国2005～2010年不同所有制工业企业效率的度量和比较

采用生产率理论中的DEA-Malmquist指数方法对我国按注册登记的7种所有制工业企业2005~2010年的数据进行分析,测度结果发现样本期间企业的全要素生产率差异微小,且国有企业效率稍高于其他企业,所有制并未构成影响企业效率的主要因素。通过对全要素生产率的拆分发现,生产率变动受外部宏观经济形势的影响较大,表现为在2008~2009年金融危机爆发期间私营企业和外资企业技术变化指数的剧烈波动。国有企业效率的稳步增长与私营企业效率的波动印证了企业生产率的增长与外部融资支持密切正相关。

Measure and Comparison of the Efficiency of Different Ownership Industrial Enterprises in China during 2005-2010

Based on the panel data of enterprises registered in 2005-2010,we used the theory DEA-Malmquist index measure and decompose productivity of seven industrial enterprises.The measure results found differences in the total factor productivity of the enterprises of the sample period were tiny,and the efficiency of state-owned enterprises is slightly higher than other enterprises,ownership does not constitute the main factors affecting the efficiency.The changes are subject to the external macroeconomic situation,the performance during the 2008-2009 financial crisis,private enterprises and foreign-funded enterprises.The technological index of private enterprises and foreign-funded enterprises changed volatility.The steady growth of the efficiency of state-owned enterprises and the private enterprise efficiency fluctuations confirmed that productivity growth closely positively correlated with and external financing support.
