碩士 === 國立政治大學 === 經濟研究所 === 96 === Since the recession in Taiwan economy has arrived in recent years, it has a great effect on the growth of the Taiwan retail sale of general merchandise. Because the market has been saturated, the competition has become fierce in this industry. How to improve the management efficiency and the industrial competitiveness in the present economic environment is the most important issue of the Taiwan retail sale of general merchandise. 　　This study uses inputs and outputs data of 25 DMUs of the Taiwan retail sale of general merchandise from 2000 to 2006, applying Data Envelopment Analysis with Metafrontier model to evaluate the operational efficiency of those firms. The findings of this study are as below: 　　1. On average, the chain convenience store industry shows more technically efficient than the shopping mall industry. 　　2. The main source for the firms being inefficient is pure technical inefficiency. The returns of scale of the firms are not much related to the types of business operation, but to the firms being the chain store ones or not. 　　3. Comparing meta-frontier model with group frontiers model, we find that there are significant differences in the average technical efficiency levels among the various types of business operation, and the chain convenience store industry is most close to meta-frontier. 　　4. According to the classification of the efficiency by Norman and Stoker (1991), we find a major part of the firms is marginally inefficient and distinctly inefficient. It implies there is a great room for the firms to improve their managerial performance. 　　5. The slack analysis indicates there are differences in the resource wastes between the department store industry and the supermarket industry. The differences mainly come from the technological differences between the two industries. The information generated from the group frontier model is helpful to improve the firms’ efficiency within the group. However, if the firms want to further improve their efficiency, they should rely on the information from the meta-frontier model, which sheds light on the technology gap among sub-industries.
