摘要
本文运用DEA-Tobit两阶段模型对中国22家酿酒业上市公司在2004-2007年期间的生产效率及其影响因素进行了分析,并结合基于非参数DEA的Malmquist生产力指数,对样本期间内酿酒企业的效率变化进行了动态评价。实证结果显示,样本期间内酿酒企业的综合技术效率平均值偏低,但除了2007年出现较大幅度下降之外,酿酒企业的综合技术效率总体上呈现上升的态势;酿酒企业在样本期间内平均全要素生产率和各年度全要素生产率均呈现不同程度的提高,且两者均得益于行业技术的进步;总资产周转率、技术人员比例和人均资本与酿酒企业效率值均呈显著的正相关,而企业规模则与酿酒企业效率值存在不显著的正相关。
Based on DEA-Tobit approach, the paper analyzes the productive efficiency and its influencing factors of the 22 listed wine-making firms in China from 2004 to 2007. Furthermore, based on the nonparametric DEA-Malmquist Productivity Index, the paper also evaluates the efficiency change of the wine-making firms. The findings demonstrate that during the period the technical efficiency of the wine-making firms is on the low level, but it also shows a rising trend in general, except that in 2007 the efficiency to a great extent declines. Second, both the average total factor productivity （TFP） and the TFP in every year during the period show a rising trend to some different extent, and both of them are greatly due to the technical progress of the wine-making industry. Finally, the total asset turnover ratio, the proportion of technical personnel and the per capital are significantly and positively correlated to the productive efficiency of the wine-making firms, but the fh＇m scale is not significantly positive correlated to the productive efficiency of the wine-making firms.
