This thesis uses case study, focus on four manufacturers in copper industry. Base on Porter¡¦s generic strategies ¡V Over all cost leadership, Focus, Differentiation, with diversification and joint venture, all together five competitive strategies as the foundations of investigate structure. And I have made the matrix chart and a survey base on the five administrative functions. I observe individually for four copper manufacturers¡¦ competitive strategies, which are approved by customers, to find out if each of them has had effect in the market. Finally, I use Michael E. Porter¡¦s competitive advantage to test the industry environment, mean while forecasting the coming 3-5 years of First Copper Technology Co., Ltd. base on the theories of SWOT and PEST as the following: 1. Having joint venture with copper manufacturers in Mainland China or East Europe to get products to compete with local manufacturers, and no longer produce low attach value products. 2. Combine Japanese or Korea wholesalers or set up a trading company to sell high attach value product in local areas in Japan and Korea. 3. Total output needs to be maintained by lowering the cost, but the products should be developed in high attach value categories like lead frame and other high level alloy products, to get alone with new developments.
