    摘要: 回購於顧客關係管理中扮演重要角色，其中為了改善過度行銷與溝通成本過高的狀況，消費者回購的議題成為線上零售業者提升經營績效的關鍵。本研究針對回購議題，首先了解如何從交易、退貨或取消等紀錄建構會員的消費行為和特徵?其次，研究如何採用XGBoost與LightGBM兩種整體學習的演算法，應用於預測消費者回購的議題，並比較何者的預測效果較優?第三，透過整體學習結合貝氏網路，探討哪些消費行為會影響回購?最後，如何從業者角度評估模型之結果，以提供完整的分析顧客回購之方法?
    本研究相較於過去學者採用少量的特徵變數進行預測，本研究進行深入的特徵工程，總共建構167個變數，提供較完整的消費行為與特徵。另外，提供 XGBoost與LightGBM 兩種演算法的預測結果，且模型準確率最高可達90%，並將各模型進行深入探討與比較分析。更進一步地將整體學習結合貝氏網路，探討重要特徵與回購之關係，不僅協助業者了解哪些消費特徵會影響顧客的回購行為，透過模型的預測結果提供業者潛在的回購名單。對於模型預測的結果，提供業者成本效益之評估，協助業者以利潤為導向的決策依據，除了可以避免消費者對過度行銷反感，亦可降低業者與會員的溝通成本，讓業者可以了解顧客需求，並提升經營的績效。
    Customer retention plays an important role in customer relationship management. In order to reduce the cost of communicating with customers and avoid over-marketing, capturing customer retention has become the key to online retail operations. This research attempts to address the following issues pertaining to customer retention. First, how can online retailers construct customer behaviors and characteristics from records of transactions, returns, and cancellations? Secondly, how to use the cutting-edge ensemble learning algorithms - XGBoost and LightGBM - to predict customer retention? Which algorithm performs better? Third, how can we combine knowledge extracted from ensemble learning the Bayesian network, to establish causal diagrams of how customer characteristics drive customer retention? Finally, how to evaluate the results of predictive models from a business perspective and perform a cost-benefit analysis of customer retention analytics?
    Compared with the past research using much fewer feature to predict customer retention, this research presents a fairly comprehensive feature engineering that results in a total of 167 variables of customer characteristics. In addition, we show that both XGBoost and LightGBM algorithms achieve prediction accuracy up to 90%. Furthermore, this study integrates ensemble learning with the Bayesian network to explore the relationship between important features and customer retention. Doing so helps retailers understand which characteristics will affect customer retention, in addition to providing a potential repurchase list based on model predictions. Finally, this study conducts a cost-effectiveness analysis according to model predictions, with the aim of helping online retailers make profit-oriented decisions for digital marketing.
