Rural industrial integration is an inevitable pathway to achieving rural industrial revitalization. Based on data from the 2020-2022 China Land Economic Survey （CLES），this study utilizes the two-way fixed effects model and the endogenous switching regression （ESR） model to explore the impact of rural industrial integration on agricultural green production efficiency.The findings are as follows： 1）Rural industrial integration significantly improves agricultural green production efficiency.Among integration patterns，technology-penetration integration，intra-agricultural integration，and industry-chain extension integration promote agricultural green production efficiency in a gradually diminishing order.This conclusion remains robust after various robustness tests and controls for endogeneity problems.2）Mechanism analysis shows that rural industrial integration promotes the improvement of agricultural green production efficiency through the dual mechanisms of scale economy effects and technology spillover effects. 3）Heterogeneity analysis indicates that industrial integration driven by leading enterprises or by leading enterprises combined with cooperatives has a significantly positive impact on agricultural green production efficiency，while integration led solely by cooperatives does not.Additionally，the positive effect of rural industrial integration on agricultural green production efficiency is more significant in southern and central regions of Jiangsu Province， but relatively limited in northern region. Based on these findings，local governments should attach importance to the positive role of industrial integration in agricultural green transformation and actively develop and cultivate industrial integration entities to promote sustainable agricultural development.
