摘要

台灣與中國大陸於2009年6月舉辦兩岸LED照明產業合作及交流會議，簽署兩岸合作意向書，開啟台灣與中國大陸LED照明產業商業合作模式，希望藉由優勢的整合，以進行全球布局。為了解台灣與中國大陸LED產業的競爭力，本研究首先應用傳統DEA方法探討2009年台灣與中國大陸29家LED公司的經營績效表現，再應用Two-Stage DEA方法探討台灣與中國大陸LED產業之獲利能力與市場能力經營績效表現。此外，透過差額變數分析及敏感度分析探究投入產出項變數對效率值之影響程度，更進一步提出管理決策矩陣供台灣與中國大陸LED產業提升經營績效及建議改善方向參考。
研究結果：傳統DEA效率值結果顯示台灣總技術效率優於中國大陸，Two-Stage DEA效率值顯示：第一階段中國大陸的獲利能力優於台灣，但分群結果顯示獲利能力無顯著差異；第二階段台灣市場能力優於中國大陸，分群結果顯示市場能力則有顯著差異。
差額變數分析研究結果顯示：台灣與中國大陸為提升獲利能力經營績效首要考量應為控制營業費用；台灣提升市場能力經營績效首要考量為增加市值，中國大陸則為增加每股盈餘。敏感度分析研究結果顯示：營業成本對獲利能力效率值影響最大，每股盈餘對市場能力效率值影響最大。

Since the cross-strait cooperation exchange conference held in June, 2009. Taiwan and China LED lighting industry have started a new cooperative business model to integrate the advantage for global strategy planning. For understand the competitiveness between Taiwan and China LED industry. Firstly, this study adopts traditional DEA approach to explore the operating performance of 29 LED companies in Taiwan and China in 2009. Secondly, we apply Two-Stage DEA approach to assess the performance of profitability and marketability efficiency between Taiwan and China LED industry. Additionally, this study utilizes slack analysis and sensitivity analysis to analyze the variations of input and output variables impact on efficiency score. Furthermore, we propose the managerial decision-making matrix to provide suggestions and first guideline for inefficient LED industry to learn with.
The traditional DEA results indicate that Taiwan has better total technical efficiency than China. The Two-Stage DEA results show that China has relative efficiency in First-Stage of profitability efficiency. Yet, no significant difference between China and Taiwan in profitability efficiency；Taiwan has significant relative efficiency in Second-Stage of marketability efficiency. Slack analysis results indicate that the priority issue for Taiwan and China to enhance their profitability efficiency is to keep operating costs under control; Taiwan has to increase market value to enhance marketability efficiency; China has to increase EPS to improve marketability efficiency .Sensitivity analysis results show that the operating costs have the most influential on profitability efficiency and EPS has the most influential on marketability efficiency.
