Customer Lifetime Value (CLV) prediction is a core task in retail and e-commerce, enabling enterprises to optimize resource allocation and formulate precision marketing strategies. Traditional CLV prediction methods rely heavily on manual feature engineering and fail to fully capture the sequential dependencies and complex relational patterns in user behavior data. To address this limitation, this paper proposes a graph neural network based user behavior sequence mining framework (GNN-UBSM) for CLV prediction and precision marketing. First, we construct a heterogeneous behavior graph integrating users, items, and orders to model multi-type interactions and temporal sequences. Second, a temporal-aware graph convolutional network (TA-GCN) with attention mechanism is designed to learn dynamic user embeddings by aggregating sequential behavior information. Third, a hybrid loss function combining triplet loss and regression loss is proposed to enhance the discriminability of user representations and improve CLV prediction accuracy. Extensive experiments are conducted on three real-world datasets (Amazon 5-Core, Beibei, and a proprietary e-commerce dataset). Results show that GNN-UBSM outperforms state-of-the-art methods by 3.2%\u22128.7% in CLV prediction error (RMSE) and 5.1%\u221210.3% in high-value user identification (F1-score). Furthermore, we derive a precision marketing strategy framework based on the model output, including customer segmentation, personalized recommendation, and churn prevention. This study provides both theoretical support for behavior sequence mining with GNN and practical guidance for enterprises to maximize CLV.<\/p>\n\n\n\n
