中國大陸白酒上市公司的共同邊界效率分析

本研究利用資料包絡分析法並採用Battese et al. (2004) 之共同邊界分析程序，以中國大陸17 家白酒A 股上市公司2002 年至2013 年的財報資料。先將以上決策單位區分為專業型白酒公司與綜合型白酒公司等兩個子群體，計算出各個子群體的技術落差比例，再進行經營效率的比較分析。實證結果顯示：(1)在共同邊界下，專業型白酒公司的平均純技術效率高於綜合型白酒公司。(2)綜合型白酒公司技術落後程度較專業型白酒公司來的大，即專業型白酒公司技術領先綜合型白酒公司。

This paper applies the metafrontier approach proposed by Battese et al. (2004) to analyze the efficiency and technology gap ratio (TGR) of 17 Chinese liquor listed companies during 2002 to 2013. The companies are divided into two groups: specialized and diversified. The efficiency scores and technology gap ratios are then computed and analyzed by the data envelopment analysis (DEA). Our major empirical findings are as follows: (1) With respect to the metafrontier, the average efficiency score of specialized companies is higher than that of diversified ones. (2) The average TGR score of specialized companies is better than diversified ones.
