摘要

近年來，台灣的數位遊戲產業蓬勃發展，並在全球性的金融風暴下逆勢成長，帶動了數位內容相關的產業價值，但在這亮麗的外表之下，卻藏著兩個隱憂；第一，在高度成長的產值下，是否也會造成能源耗用量的大幅增加？第二，在高能源價格下，是否會影響到整體產業的發展？基於這兩項因素，本研究希望從能源的角度去探討遊戲產業經營績效，並以資料包絡分析法找到能源與該產業的關連性。
本研究收集13家上市櫃遊戲公司於2008及2009年的營運資料，利用DEA的CCR及BCC模型，求得兩個年度的技術效率、純技術效率、規模效率與規模報酬狀態，並輔以Malmquist生產力指數分析跨期效率之變化，再經由差額變量及敏感度分析來探討能源耗用與經營績效之關連性。研究結果顯示，這兩個年度的整體效率差不多，廠商之純技術效率普遍較佳，大部分的廠商都處於規模報酬遞增的狀態；而由敏感度分析得到能源耗用對於遊戲產業之影響程度並不顯著，若能源價格提昇，對於該產業的發展應該有正面的助益。

In recent years, game industry was flourished in Taiwan, and grew despite current trends for global financial meltdown. It also produced the value chain of digital content industry. But under this sharp semblance has actually hidden two concealed worries. First, in the case of high growth output value, could it cause a sharp increase in energy consumption? Second, in the case of high energy price, could it cause the development of game industry? Base on the above two factors, we want to find the relation between game industry and energy through data envelopment analysis, and hope to find the perspective from energy performance of game industry.
In this research, we collected 13 listed game companies operating data in 2008 and 2009, and try to calculate technical efficiency, pure technical efficiency, scale efficiency and returns to scale through DEA-CCR and DEA-BCC mode. Then we use Malmquist productivity index to analyze intertemporal changes in efficiency, using slack variable analysis and sensitivity analysis to find the relation between energy consumption and managerial performance. The finding shows that the overrall efficiency of two years are equivalent, the pure technical efficiency of game companies are general better, and almost all companies are in a state of increasing returns to scale. Energy consumption and the game industry does not significantly influence through sensitivity analysis. If energy prices increase, the development of game industry should have a positive benefit.
