摘要
高效率空調的市場擴散與提高市場滲透率,已成為國家落實溫室氣體減量目標的最重要政策與 措施。本研究首先應用世代Bass技術擴散模型,評估我國高效率空調的技術擴散(或市場規模),以 及內生市場滲透率。研究結果顯示,我國住宅部門空調市場規模約11.4百萬台,高效率(變頻)空調 取代定頻空調滲透率的彈性值為−1.40。據此,估算2019年,變頻空調市場滲透產生的累計節電量 約946.3百萬度電,以及481,684.3噸CO2e的減排量。本研究進一步,建立滲透率誘因設計的理論模 型,探討不同誘因機制設計的影響效果。本研究結果,顯示,(1)補貼對象:中游(零售商)、下游(消 費者)補貼,相較於上游補貼(生產者),對促進高效率產品較具確定性及較佳效果。(2)補貼工具型 態:價格補貼優於所得定額補貼;成本補貼優於利潤補貼。本研究結果,具有高度政策與市場行銷 意涵,可以提供政府施政與產業產品推廣策略之參考。

The market penetration of high-efficiency air conditioners have become the most important policies and measures to respond to greenhouse gas emissions target in Residential sector in Taiwan. This study used the successive-generation Bass model to assess the market scale and penetration rate. Furthermore, this article established a theoretic model to discuss how the incentive for facilitating the penetration rate of high-efficiency air conditioners in Taiwan. The key results presents that the elasticity of the inverter air conditioners to substitute to the fixed-frequency air conditioners is -1.4. This could be estimated that the total electricity savings was about 946.3 million kWh in 2019, and then the total greenhouse gas emissions reduction is about 481,684.3 tons CO2e.The normative model indicated that: (1) Midstream (retailers) as well as downstream (consumer) subsidies, compared to upstream subsidies (producers), are more attractiveness.
