碩士 === 長庚大學 === 企業管理研究所 === 89 === Although the development of manufacturing industry has made the great contributions to Taiwan’s economy, it has also made significant impact on Taiwan’s nature environment. This research uses both the Ecological Footprint Method and DEA （Data Envelopment Analysis） Method to measure the ecological footprint, Eco-efficiency and production efficiency for Taiwan’s manufacturing industry. It not only estimates the impact on Taiwan’s nature environment resulting from industrial development but also compare, among each sector of the manufacturing industry, the relative performance on ecological footprints, eco-efficiency and production efficiency. And point to the direction of improvement by DEA Method. The ecological footprints of manufacture industry, with the annual increase of 5﹪per year on the average. The top three sectors are chemical products, basic metal and non-metallic mining. The top four sectors with most serious impact on Taiwan’s environment are pulp paper ＆paper products, food, chemical materials, and textile mill products. Since The pollution of the three sectors of chemical materials, basic metal and non-metallic mining are 62.07﹪of total pollution, this three sectors can be considered heavy pollution. The top four sectors of added value by each ecological footprint are electrical ＆electronic machinery ,transport equipment, machinery ＆equipment and printing processings. This indicates they are more efficient in utilizing nature resources. Comparing each sector’s utilization of resources with the improvement in production efficiency, we can see that, even thought production efficiency has bee improving, the aggregate ecological footprints have also been increasing persistently. Particularly for the sectors of electrical power and electronic machinery, petroleum and coal products, chemical materials, and basic metal. It is clear that, in addition to technical factor, human attitude toward consumption plays an important role in conserving nature resources. By the use of DEA method, we can conclude that only printing processings, electrical ＆electronic machinery are the truly relative efficient units. The first orders of potential improvement are 「add value item 」. It can also be seen from the relationship chart between eco-efficiency and technological efficiency, the differences in performance among sectors are great but yearly differences in performance are small. This lead to the conclusion that, at least to some extent, the differences are due to each sector’s special character. Therefore, Taiwan must proceed with the adjustment in the direction of industrial development in the viewpoint of eco-efficiency.
