本研究在於探討台灣太陽能光電產業內各公司其經營績效之評估，應用資料包絡分析法(Data Envelopment Analysis, DEA)找出單一指標，藉由效率值來判斷各公司在經營上其投入與產出的改善的方向，以作為專業經理人在擬定重大決策時判斷的依據。同時找出產業中標竿企業，了解其最佳經營績效的投入與產出，以作為未來有意跨入此產業廠商之參考。
;In recent years, the crude price rose unceasingly, in addition “the Kyoto Protocol” globally control the greenhouse gas emissions, urged various countries to start to take each kind of new energy and the vicarious energy. From 2004 on, the photovoltaic industry vigorous development, the entire supply chain from the upstream polycrystalline silicon, the silicon wafer, the solar cell, the module to the downstream system installation. All throughputs have over 30% year compound growth rate, therefore the domestic manufacturers in photovoltaic industry will have a very big growth space.
This research focus on discusses in Taiwan photovoltaic industry appraisal of the various companies its management achievements, applicating Data Envelopment Analysis to discover the sole index, by means of efficiency value to judge various companies in the management its inputs and outputs with the improvement direction, as a judge basis when the specialty draws up the major decision. Simultaneously discovers in the industry the benching mark enterprise, understood that its best management achievements the inputs and outputs, as the reference of who will intend to stride in this industrial in the future.
The object of study including four silicon wafer manufacturer and four solar cell manufacturer in market, data period is from 2005 to 2007, the selected appraisal target including three inputs: the overhead cost, the property grand total, the working condition, and two outputs: gross profit , revenue. Using Data Envelopment Analysis(DEA) and Malmquist Productivity Index(MPI) as the appraisal method to understand each Taiwan photovoltaic industry entrepreneur's relative management achievements and the situation of cross year achievements change, and to submit the management achievements improvement proposal based on the analysis and the discussion from the computed result.
