中文摘要
有效的前進部署,能夠控制銷售中的投入以及降低損失,掌握產品以及物流的安排。對於季節性產品來說,他們本身具有銷售週期,而週期不全然是完全相同,有時也會受到外在條件的影響而提早或延後。此外,不單是季節時間影響銷售,進一步理解真正影響季節性的原因很重要,以便在進入市場的最佳時機前,做好前進部署。本研究以家用冷氣機的銷售為研究目標,將房屋交易和天氣因子作為探討影響銷售的因子。
本研究運用多元迴歸分析,分別採用虛擬變數和固定效果模型等方法,從不同觀點探討這些因子如何影響家用冷氣機的銷售。同時,特徵價格模型也在本研究中運用,分析異質性產品的特徵和價格的彈性。結果顯示,房屋交易和相關天氣因子對家用冷氣機的銷售具有影響力。另一方面,節能指標的產品特徵、年耗電量,以及機台樣式(窗型、分離式、一對多分離式)等特徵明顯地對家用冷氣機的價格有影響。這也反映出當今的節能政策,以及家用冷氣機的購買傾向。基於這些分析結果,在考量外部因子的變化後,可以建立前進部署策略,以便掌握家用冷氣機市場的銷售。
Abstract
Taking effective preventive measures can control the cost and decrease the loss in sales to prepare the products and arrange the logistics properly. Seasonal products have own sales period, and the periods are not totally same. These periods sometimes happen early or late. Besides, the sales is not simply influenced by the season times. Figuring out what actually influences the sales to further execute preventive measures before entering the market is crucial. This study took the sales of room air-conditioners as the analysis target to explain how the external factors, which were the house transactions and weather factors, influence sales.
Multiple linear regression analysis was designed with dummy variables and fixed-effect model to be analyzed from different perspectives. Also, the hedonic price model was utilized to find out the elasticity between prices and product specifications. The results indicated that the room air-conditioners sales can be influenced by the house transactions and weather factors. In contrast, the energy-efficiency index, annual power consumption and different types (window, split, multi-split) of room air-conditioners influence room air-conditioners price more. This reflects the energy-saving policy nowadays and purchasing tendency. With the results, the preventive measures can be established considering the changes of external factors to seize the sales time.
