由於經濟發展快速，家庭所得提高，因此對於能源的使用量不斷提高。民國90年，經濟部能源局正式啟動節能標章政策，目的是為了提高能源效率，降低二氧化碳的排放，並達到節約能源的目標。本文以通過節能標章數目最多的冷氣機產品為研究對象，以特徵價格模型分析冷氣產品特徵與價格之間的關係，對於能源效率較高及具有節能標章的冷氣產品，消費者是否願意花費較高的金額來購買。此外，針對節能冷氣產品作概略分析，探討能源效率相關變數與其他屬性變數之間的關係。
本研究使用的資料取自節能標章網站所列之節能冷氣型錄及PChome網站所列之冷氣產品價格與各項特徵。研究結果顯示，能源效率比值高者及節能標章產品，估計出顯著的正向效果，及其他特徵變數如冷房能力、冷氣適用坪數及具有暖氣功能者，皆有比較高的願付價格。使用節能冷氣資料，設定能源效率比值為應變數的估計結果與能源效率比值的定義相符，此外，估計出日立品牌的冷氣存在較高的能源效率比值。

As rapid economic development, family income increased, so the rising use of energy. 90 years, the MOEA Bureau of Energy implements the Energy Label policy, which aims to improve energy efficiency, reduce carbon dioxide emissions and achieve energy conservation goals. This article use air-conditioner, which is the largest number of energy-label products as the research object. Use hedonic price model to analyze the relationship between characteristics and prices of air-conditioner. For more energy-efficiency products and the air-conditioner having energy-saving mark, whether consumers are willing to spend higher amount to buy. In addition, for energy-saving air-conditioning products for broad analysis of the relationship of energy efficiency-related variables and other attributes.
This study used data was taken from the Energy Label Web site listed in the catalog of energy-saving air-conditioning and PChome websites listed in the price and the characteristics of air-conditioning products. The results showed that the high ratio of energy efficiency and energy-saving label products were to estimate a significant positive effect, and other characteristics of variables such as the cooling capacity, air-conditioning suitable number of ping and a heating function of the number of those, there are willing to pay higher prices. From energy-saving air-conditioning data, set the energy efficiency ratio for the response variable to the estimated results to the definition of energy efficiency ratio in line. In addition, there exists that Hitachi brand of air-conditioner with higher energy efficiency ratio.
