Abstract: Rural industrial integration plays a crucial role in boosting county economic resilience, significantly enhancing economic stability and risk management capabilities. Based on panel data from 53 counties in Zhejiang from 2008 to 2023, this study constructs a mechanism model to analyze how rural industrial integration affects economic resilience, using methods such as two-way fixed effects, intermediary test and threshold tests. The results show that: 1) rural industrial integration strongly promotes county economic resilience; 2) rural industrial integration enhances county economic resilience through human capital effects; 3) rural industrial integration exerts a strongly positive effect in northeastern Zhejiang, whereas it poses a slight negative impact on the southwestern part of the province. Furthermore, its influence is markedly positive during the recovery-adjustment and shock-adaptation phases, but becomes relatively weak throughout the impact resistance period; 4) There is a single threshold effect of innovation ability on the economic resilience of counties in rural industrial integration. Accordingly, the study suggests enhancing human capital by deepening rural industrial integration, advancing county-level technological innovation, optimizing industrial park agglomeration, and adopting localized development strategies to strengthen county economic resilience.
