摘要


近年隨著節能減碳的議題興起,新能源開始受到重視,LED照明產業為其中的重要產業,工研院能源與環境研究所統計,要是台灣地區有25% 白熾燈泡及100% 日光燈被白光LED 取代,每年可省下110 億度電力相當於一座核能發電廠的發電量,由於LED照明在節能減碳上的效益,各國政府紛紛開始立法扶植補貼LED照明產業,而LED照明本身也具有傳統照明不具備的優秀性能,然而現階段LED照明的價格仍然過高,技術進步對LED照明產業的市占擴大及普及來說是關鍵問題,目前市場上對LED照明的技術進步率看法卻有一些分歧,本研究以美國能源局所公佈的預測報告做為基準,以行政院主計處2006年所公佈的產業關聯表做為資料來源,使用動態的可計算一般均衡模型,做在不同的技術進步率假設下的模擬,希望在量化的基礎下,對整體經濟及假設做客觀的預測,以提供參考。模擬結果發現若技術進步率如美國能源局的報告所預測,在每年技術進步率平均為14.8%的假設下,LED照明產業的實質產出成長率和實質出口成長率與基線值相比有相當可觀的增加,而在產業的實質就業成長率方面,若外生設定的技術成長率越高,則會使LED照明產業的實質就業成長率減少越多,原因為當產業的總要素生產力上升時,廠商可以以較少的雇用要素達成與上升前同樣的產出水準,因此總要素生產力的上升會使廠商傾向少雇用要素,進而使實質就業人數減少;在模擬結果方面,本研究以美國能源局的報告所預測的每年平均14.8%技術進步率為基準,分別在較低(12.8%)及較高(16.8%)的技術進步率之下 做模擬比較,LED照明產業部門和傳統照明產業部門在不同的技術進步率假設下所得的結果略有不同,但即使是在最低的技術進步率假設下,LED照明產業的產出和出口成長均相當不錯,而LED照明產業的技術進步除了對傳統照明產業有較大的影響之外,對其它部門的影響十分微小,在總體經濟變數方面,LED照明產業的技術進步所造成的影響也十分輕微,原因為我國LED照明產業的產值太小,因此即使擁有較高的技術進步率也很難對整體經濟發生影響,後續研究或可考慮LED照明的減碳功能,就LED照明產業取代傳統照明產業所達成的減碳效果做社會福利改善的分析。

Recently,LED lighting industry has been on the sopt light.The need for saving energy has made the so-called ‘green energy’ industry became more and more important.Governments have spent a lot cash and effort to foster these industry, and have so far made some improvement.The trend of developing green energy is gathering momentum and is there to stay.LED lighting industry is on the rise, accroding to many research, LED lighting could save much electricity and therefore reduce the emmision of green house gas. LED lighting bulbs could last much longer than traditional ones,this feature along with other advantage like better safety and warmer lighting color make the great potential of LED lighting able to take place of traditional lighting.But the cost of it has always been the problem,the technical progress has been vital to the development of LED lighting industry.However, there is not a coherence consensus of how fast would the technical improves.This paper intend to analyze the effect on the industry and the whole economy when take the technical progressing of LED lighting industry as a external variable by using a CGE model.The purpose is to offer a quantitative result on objective basis
