Abstract:	2020年起Covid-19在世界漫延與禍害，疫情肆虐下防疫商品已成生活必需品，口罩不離口已是日常景象，因此本研究使用110年9月至111年3月間，從康是美、屈臣氏、博客來、PChome、Momo和Yahoo等六大網路購物平台蒐集之口罩資料，以及使用109年7月至111年4月取自財政部關務署之口罩出口數量和美國Johns Hopkins University的確診人數統計資料。線上購物平台口罩資料部分使用半對數特徵價格和Box-Cox轉換模型，探討口罩基本特性、功能、認證與檢測和各大平台等變數對口罩價格之影響；口罩出口模型則是選自出口前四大地區美國、香港、日本和新加坡，探討當地之每月累計確診人數、每月新增確診人數和口罩月出口平均價格對口罩出口數量之影響。半對數型態之特徵價格模型實證結果顯示，變數口罩數量、彩色、立體型、圖案、N95、活性碳、國際認證標章、國內CNS標章及雙鋼印皆為正顯著；拋棄式口罩、符合PM2.5功能口罩和細菌過濾率皆為負向不顯著；原產地為台灣製造之口罩和具醫療功能口罩皆為負顯著；網路平台特徵變數中，博客來為正顯著、Momo、PChome和Yahoo為負向顯著、康是美為負向不顯著。 Box-Cox模型實證結果顯示，其中有N95功能之口罩其隱含價格為正向最大；其中原產地為臺灣生產之口罩其隱含價格為負向最大；口罩出口模型實證結果顯示，新加坡為不顯著，日本僅每月累計確診人數在靜態模型中為負顯著，香港的統計結果與預期不符，美國月出口平均單價在靜態模型中為負顯著，在具有落遲一期的模型中，月出口平均單價都只有當期是負顯著。 ;Since Covid-19 has ravaged the world, epidemic prevention commodities have become daily necessities. Therefore, this study used the mask data collected from six major online shopping platforms from September 2021 to March 2022, the export quantity of masks from the Customs Administration of the Ministry of Finance from July 2020 to April 2022, and the statistical data of the number of confirmed cases from Johns Hopkins University in the United States. This study used the semi-logarithmic form of the hedonic price and the Box-Cox model to analyze how the characteristic variables affect mask prices. The mask export model is selected from the top four export regions, the United States, Hong Kong, Japan, and Singapore to investigate the effect of the cumulative monthly number of confirmations, the monthly number of new confirmations, and the average monthly export price of masks on the export quantity of masks. The results of the semi-logarithmic price model showed that the number of masks, color, three-dimensional type, pattern, N95, activated carbon, international certification, masks with domestic CNS mark, and masks with double seal mark were all positively significant; disposable masks, masks with PM2.5 function, and bacterial filtration rate were all negatively insignificant. Among the online platform characteristics, Books online bookstore is positively significant, Momo, PChome, and Yahoo are negatively significant, and Cosmed is negatively insignificant. The Box-Cox model empirical results show that the implied price of masks with N95 function is the largest in the positive direction. And the implied price of masks made in Taiwan is the largest negative. The export model empirical results show that Singapore is insignificant, Japan is negative in the static model only for the monthly cumulative number of confirmations, Hong Kong is not as expected, and the monthly average unit price of U.S. exports is negative in the static model. In the model with a lag period, the average monthly export unit price is negative in the current period only.
