In recent years, the rapid growth of the Internet economy has driven a sharp increase in global cross-border e-commerce sales, presenting vast market potential. However, compared with domestic e-commerce, cross-border platforms face greater challenges in logistics, warehousing, and supply management, while product sales abroad are more volatile due to user preferences, cultural differences, and environmental factors. To address these issues, this paper develops a Gradient Boosting Decision Tree (GBDT) -based sales prediction model by selecting key influencing factors from historical sales data, product information, and customer reviews. For comparison, Backpropagation (BP) neural network and Autoregressive Integrated Moving Average (ARIMA) models are also introduced. Experimental results show that the GBDT model achieves a significantly lower average relative error than the other two models and performs better than the actual prediction performance of Company M, demonstrating that the proposed method improves forecasting accuracy and holds practical application value.
