This study employs the Fuzzy Comprehensive Evaluation Method to establish an assessment framework for the sustainable development capacity of China’s forest product international trade. By integrating the Entropy Weighting Method, it measures and analyzes the sustainable development level of China’s forest product trade from 2015 to 2024 across three dimensions: economic benefits, social benefits, and environmental and ecological benefits. The results indicate that China’s sustainable development capacity in forest product trade has shown a significant upward trend, with the relative proximity index increasing significantly from 0.2751 in 2015 to 0.6583 in 2024. The growth rate of the comprehensive score was relatively small from 2015 to 2022, while it increased significantly from 2022 to 2024, rising from 0.5528 in 2022 to 0.6583 in 2024, with an average annual growth rate of 19.08%. Regional development imbalances are prominent, with the comprehensive evaluation value of the eastern region (0.7084) significantly higher than that of the central (0.6436) and western regions (0.5551).
