This study investigated the operational performance of logistics and warehousing industries of various counties/cities in Taiwan from 1991 to 2006. In addition, data envelopment analysis was used as the operational performance assessment model, where the number of employees, labor remuneration, floor area, and net value of fixed assets were used as input, gross output was used as output, and current assets were used as intermediate goods. Efficiency analysis, slack analysis, Malmquist productivity index analysis, and dynamic network DEA were performed in order to understand the general status of the operational efficiency of logistics and warehousing industries of various counties/cities. Moreover, this study investigated the direction and range of efficiency improvement and provided such information as reference for development of governmental regional industrial policies and improvements of regional industrial competitiveness.
Efficiency analysis found that, in the past 15 years, an increasing return to scale was observed in the development of logistics and warehousing industries in 23 counties and cities in Taiwan. The operational scale has room for expansion, and was at the growth phase of the industry life cycle. Malmquist productivity index analysis showed that, from 1991 to 2006, the average change of total factor productivity, technical efficiency, and technological innovation were all greater than 1. Such information suggested that, over the past 15 years, technical efficiency and technological innovations of logistics and warehousing industries in Taiwan made significant progress. In consideration of the effects of inputs, deferred outputs, and intermediate goods, as opposed to static DEA, dynamic network DEA had greater application to the assessment of the operational performances of regional industries.
