| 摘要: | 台灣四面環海且受地理位置的影響，一年四季都有不同的氣團以及季風，根據交通部中央氣象局顯示，在2021年台灣的平均年總雨量為1997.4毫米，大約為世界年平均降雨量的兩倍以上，也因雨水充沛，導致相對濕度偏高，然而濕度高會影響人們的生活品質，無論是物質上或身體上都會遭受到影響，為了降低濕度高所帶來的不適，民眾則可選擇購買除濕機，故除濕機對於我國而言是相當重要的家電產品，但鮮有文獻針對除濕機作探討。本研究係提示何種家庭因素會影響除濕機的擁有率，另透過半對數特徵價格模型探討除濕機的價格是受到何種屬性(或特徵)影響。
使用羅吉斯模型衡量並透過中央研究院所提供之行政院主計總處家計收支調查資料探討除濕機擁有率，該調查資料年份為2018年至2021年，共4年。實證結果顯示經濟戶長的性別、65歲以上戶內人口數及住宅建坪與除濕機的擁有率顯著負相關；而經濟戶長的年齡、教育程度、所得收入總計、戶內人口數及住宅所屬與除濕機的擁有率顯著正相關。
使用半對數特徵價格模型衡量並透過台灣購物網站( momo購物網及PChome24購物網)及各品牌之官方網站蒐集有關除濕機之價格及屬性(或特徵)之相關資料，資料年份介於2022年9月至12月，共187個觀察值。實證結果發現，在未控制品牌前，解釋變數中全機保固、重量、水箱容量、每千瓦的除濕能力、負離子清淨及過濾pm2.5功能皆與除濕機的價格顯著正相關，而產地及能源效率等級與除濕機的價格顯著負相關；在控制品牌後，大部分解釋變數的顯著水準與符號與未控制前相同，除了全機保固及產地。全機保固及產地雖然仍然會對除濕機價格產生影響，但其影響力已不具顯著性。
;Taiwan is surrounded by the sea and influenced by its geographical location, experiencing different air masses and monsoons throughout the year. According to the Central Weather Bureau of the Ministry of Transportation, Taiwan′s average annual rainfall in 2021 was 1997.4 millimeters, which is more than twice the world average annual precipitation. The abundant rainfall leads to high relative humidity, which can have negative effects on people′s quality of life, both physically and materially. To alleviate the discomfort caused by high humidity, people can choose to purchase dehumidifiers, which are considered one of the important large pieces of furniture in Taiwan. However, there is limited literature exploring dehumidifiers. This study aims to investigate which household factors affect the ownership of dehumidifiers and to explore which attributes or features affect the price of dehumidifiers using a semi-logarithmic hedonic pricing model.
Logistic regression is used to analyze the ownership of dehumidifiers using household income and expenditure survey data provided by the Academia Sinica from 2018 to 2021. The empirical results show that the gender of the head of household, the number of household members aged 65 and over, and the floor area of the house have a significant negative correlation with the ownership of dehumidifiers. On the other hand, the age, education level, total income, number of household members, and residential location of the head of household have a significant positive correlation with the ownership of dehumidifiers.
Using a semi-logarithmic price model to measure and analyze dehumidifier prices, data on prices and attributes or features of dehumidifiers were collected from Taiwan′s online shopping websites (momo shopping network and PChome24 shopping network) and various brand websites. The data were collected from September to December 2022, and there were 187 observations. The empirical results showed that, before controlling for brand, the warranty, weight, water tank capacity, dehumidifying capacity per kilowatt, negative ion purification, and PM2.5 filtering functions were significantly positively correlated with dehumidifier prices, while the country of origin and energy efficiency rating were significantly negatively correlated with dehumidifier prices. After controlling for brand, most of the significant levels and symbols of explanatory variables were the same as those before controlling for brand, except for the warranty and country of origin. Although the warranty and country of origin still have an impact on dehumidifier prices, their influence is no longer significant. |
