基于DEA模型的中国家电上市公司效率实证分析

基于规模报酬可变的DEA模型和Malmquist指数方法,利用中国22家家电上市公司2006-2011年间的截面数据和面板数据,从静态视角和动态视角双维度考察了这一时期中国家电上市公司效率状况.研究发现,2006-2011年期间中国家电上市公司技术效率状况不佳,平均值为0.87,技术效率经历了下降后缓慢上升的趋势;中国家电上市公司动态效率较低,平均增长率为2.3%,且动态效率具有明显的波动性,缺乏持续的增长趋势,技术进步是中国家电上市公司动态效率增长主要动力,技术效率对其增长贡献较小.

An Empirical Analysis on Efficiency of Appliances Listed Companies in China Based on DEA Model

Based on the DEA model with variable return to scale and Malmquist Index, from the static and the dynamic angles,this study showed the efficiency of 22 appliances listed companies in China from 2006 to 2011,using both cross-section data and panel data. The research found that from 2006 to 2011 the technical efficiency of the appliances listed companies was not good,with an average value of 0.87.The technical efficiency draped down and trended up slowly.It also showed that the dynamic efficiency of Chinese appliances listed companies was low,with a growth rate of 2.3%and a obvious volatility.It lacked of persistent growing trend.Technical progress was the major driving force of the dynamic efficiency of Chinese appliances listed companies,however,technical efficiency contributed little to its growth.
