摘要


我國再生能源發展條例已於2009年6月經立法院三讀通過,明訂未來再生能源推廣目標及各類別所占比率,其中以太陽能技術發展為政府主要扶植產業重點,期許在2015年能成為全球第三大太陽能電池生產國,年產值4,500億元。由於全球太陽能市場受惠於各國獎勵措施包含電價補貼、投資抵減、低利貸款等,2007-2008年全球太陽能系統安置量CAGR高達160%,2009年下滑至15%,原因在於2008年底金融風暴及西班牙修正補貼上限所致。因此,本文探討在2007-2009年15家台灣矽晶太陽能光電廠商之生產效率表現,方法採用Battese and Coelli(1995)提出隨機邊界模型為基礎,且進一步分析研發密集度、預付購料款、購料擔保保證、垂直整合、產業鏈對技術效率之影響,以期能提供廠商生產決策之參考。 實證結果如下: 1. 整體台灣太陽能光電產業之平均規模報酬大於1,顯示具有規模經濟。 2. 研發密集度對技術無效率呈現顯著正相關,即研發密集度越高,技術效率越差; 3. 預付購料款對技術無效率呈現顯著負相關,即預付購料款越多,技術效率越佳; 4. 購料擔保保證對技術無效率呈現顯著正相關,即購料擔保保證越多,技術效率越 差; 5. 經營上游矽晶圓廠或中游電池廠皆比下游模組廠更能提升技術效率。在平均效率 表現上,上、中、下游分別為0.8757、0.7901、0.6699,顯示上游整體表現 優於中、下游產業鏈; 6. 垂直整合對技術無效率呈現顯著負向影響,表示廠商進行垂直整合可提升技術效 率。在平均效率表現上,垂直整合廠商優於整體太陽能光電產業、未垂直整合廠 商。

In Taiwan, Renewable Energy Development Act is passed by the Legislative Yuan at 6, 2009 and the law explicitly requires the promotion goals of renewable energy and the categories’ shares, of which the development of solar PV technology is a key project of the Government's supporting industry. In 2015, Taiwan’s solar cells will become the third largest supplier of the global and the annual output value will reach 4,500 billion. As the global solar market is to benefit from the country’s incentives including price subsidies, tax credits, low-interest loans, The CAGR the volume the global cumulative PV power installed in 2007-2008 was up to 160% and in 2009, fell to 15% due to the end of 2008 financial crisis and Spain’s amendment to limit subsides. Therefore, this study will focused on production efficiency of performance of 15 silicon-based solar firms in Taiwan during 2007 to 2009. The method adopts Battese and Coelli (1995) model of stochastic frontier and further analyzes R&D intensity, prepaid purchases, guarantee purchases, vertical integration and different industry chains on the influence of technical efficiency. At last, it would give some suggestions for producers. The empirical results are as follows: 1. The return to scale about Taiwan’s overall solar PV industry is greater than 1, means that it is economies of scale. 2. R&D intensities have a significantly positive relationship with technical inefficiency. That is the higher R&D intensities, the worse technical efficiency. 3. Prepaid purchases have a significantly negative relationship with technical inefficiency. That is the more prepaid purchases, the better technical efficiency. 4. Guarantee purchases have a significantly positive relationship with technical inefficiency. That is the more guarantee purchases, the worse technical efficiency. 5. Operating the upstream silicon wafer or the middle solar cell is to enhance technical efficiency more than the downstream module. The average technical efficiency of the upstream, middle and downstream is individually 0.8757, 0.7901, 0.6699, show that the performance of the upstream is better than in the upstream and downstream industry chain. 6. Vertical integration has a significantly negative relationship with technical inefficiency, represents that vertical integration could enhance technical efficiency. On the other hand, the performance of vertical integrated firms are superior to the overall solar PV industry and non-vertical integration.
