在電子資訊爆炸時代，人類所賴以交換訊息的機器與設備，需全面倚靠電力之供應。電力除了是主要的使用能源，且在替代能源之研發上，電力也是不可或缺的一環。而電力之輸送需有輸配電網路系統，電線電纜即擔任了電力輸配功能之重要角色。電線電纜業為我國的關鍵基礎工業之一，為供應電子、電器、資訊、通訊與建築業界的重要產品。 本研究運用Charnes, Cooper and Rhodes (1978)提出之資料包絡分析法(Data Envelopment Analysis; DEA)，評估我國9家上市櫃電線電纜公司2010年至2013年間經營績效。選用固定資產、員工人數、營業成本和營業費用為投入項，營業收入淨額為產出項，並加以分析。 本研究的結果顯示，2010年至2013年間，連續四年9家的總平均技術效率變動是呈現衰退的現象，純技術效率及規模效率平均值也是呈遞減的趨勢，總要素生產力部分在2011~2012年間明顯退步，但2012~2013年已有回升。 Electric information in the age of explosion, people fully rely on the supply of electric for using machine and equipment exchanging the information. Electric is the main energy. It needs the system of transporting network for conveying electric, and the cables play this important role. Electric wire and cable industry is one of the crucial industries in our country; that is a major product for electronic, electric equipment, communication and building industries. This study adopt the DEA (Data Envelopment Analysis) submitted Charnes, Cooper and Rhodes in 1978, to evaluate the operating performance from 2010 to 2013 for 9 Electric wire and cable companies in the stock market, with input---fixed assets, labor quantity, operating cost, operating expenses, and output---net operating revenue to analyze. The results show the situation that average technologic efficiency change of 9 Electric wire and cables companies is a decline, and also on pure technologic efficiency and scale efficiency. The whole elements of productivity fail from 2011 to 2012 as well but rise again from 2012 to 2013.
