零售業在價格破壞的潮流中,經年累月的進行價格促銷,以多樣化的促銷方案吸引消費者來店消費,期望能夠薄利多銷,獲得最佳效益。因此必須藉由交易記錄,輔以消費者個人資料,建構消費者在不同促銷情境下之購買模式,以利制訂行銷決策。 本研究使用國內某一大型連鎖商店2003年6月30日至2003年9月29日之優酪乳交易資料,利用層級貝氏理論分析不同品牌之降價幅度,對消費者購買決定之交互影響,再就人口統計變數觀察不同消費者對不同品牌促銷之偏好。 研究結果顯示,在零售賣場,降價促銷是消費者最偏好的促銷方式,而品牌是影響促銷效益的重要因素。在競爭環境下年齡、性別及家庭人口數等三項人口統計變數,會間接影響消費者對降價幅度之偏好程度。
