| Summary: | 碩士 === 國立成功大學 === 資源工程學系碩博士班 === 96 === Steel industry is one of the basic industry in developed country and used to be the symbol of the national power and property. It is not only able to push other industry forward, but also be the role improving other industrial development.
As a result of absence in resource, the efficiency and cost has been the essentiality. Since the steel industry was in-need in Taiwan, the price had changed obviously by other country. The international competition has been the most important issue in Taiwan after joining WTO. The specific factory with lots kinds of products and more than 50% market occupied was suitable to analyzed the competitive relationship between Taiwan and the global in steel industry.
With application of Date Envelopment Analysis (DEA) approach, this study conducted with the performance analyzation among 31 steel mills, which was composed of one in Taiwan and thirty in the world. Listing the way and option the specific mill needed to improve. Also, this study investigated the efficiency change of those steel mills by the Malmquist index to complement the defect of DEA.
In this study, the specific mill had not affected by the risen of the in-ternational steel price since 1998~2004 because of the stable performance, but not well done on the fourth extension in 1997. The specific mill has operating advantages on material cost and the amount of employees, and this is the key point of the input factor in DEA. How to make a long-term contract of material commerce is the first key in improving operating ef-ficiency in the mills lack of material. By Malmquist index, the specific mill had operated effectively since 1997~2004 but total factor productivity change had done less well than before cause by the technique decline since 2002~2004. In practical contrast, we found this had not resulted from the decline of the specific mill, but the growth, diversification and internationalization of industries in other countries. So the specific mill would better to use the positive financial management to promote the technique, scheme the new production line, raise up the product quality and strengthen the growth downstream factory to level up the competitive.
