應用 DEA 方法評估台灣LED產業經營績效之研究

近年來隨著物質生活的不斷提高,人們的環境保護意識亦不斷增強。世界自然基金會多年前便開始倡導“地球一小時”活動，但活動近兩年還是受到一些質疑。其實，如今隨著LED照明的普及已經有了解決的方法。根據《紐約時報》的報導，如果LED照明技術全部取代傳統的照明燈泡，僅就節約電力消耗而言，就能夠在短短的20年內為將全世界的二氧化碳排放減少50%。由此可見，LED照明的普及是推進節能減排的有效舉措。本研究以資料包絡分析法選擇營業成本、固定資產及員工人數為投入項，營業收入淨利為產出項，分析台灣LED 企業經營績效。其分析資料樣本為經濟新報資料庫(TEJ)所收錄的16 家上市上櫃公司為研究對象，並因考慮母群體的同質性，將此16家公司分為上中游及下游各8家的A、B群做研究，研究期間從2011 年至20012年。本研究認為LED上中游廠商應提升其技術層級，瞭解市場趨勢並積極與國際LED大廠進行策略聯盟，以取得專利授權，積極創新與研發，並提升其競爭優勢。下游廠商可採取與上游廠商類似之策略，以低成本的競爭優勢設法與握有專利的大廠進行代工聯盟，進而獲得專利授權，共同擴大市場佔有率。

In recent years, with the increasing material, people's awareness of environmental protection has also been enhanced. WWF years ago started advocating "Earth Hour" activity, but also activities over the past two years is the subject of some question. In fact, today, with the popularity of LED lighting methods already have been resolved. According to the New York Times reported that if all LED lighting technology replacing traditional light bulbs, only in terms of savings in electricity consumption, it can, in just 20 years to reduce carbon dioxide emissions around the world by 50%. This shows that the popularity of LED lighting is an effective initiative to promote energy-saving emission reduction. In this study, the data envelopment analysis to select operating costs, fixed assets and number of employees to put items, net operating income for the output variables, analysis of Taiwan's LED business performance. Its analysis of the data sample for the Economic Journal Database (TEJ) received recorded in 16 listed companies for the study, and in consideration of the homogeneity of the population, and this 16 companies into the midstream and downstream of each 8 A , B group doing research, the study period from 2011 to 20012 years. This study suggests that the LED midstream companies should enhance their technical level, to understand the market trends and actively with the international LED manufacturers strategic alliances to obtain patent licenses, active and innovative research and development, and enhance their competitive advantage. Downstream and upstream firms may take a similar strategy, low-cost competitive advantage to try and hold the patent carried OEM manufacturers alliance, thereby obtaining patents jointly expand market share.
