As an advanced productive force characterized by high-tech，high-efficiency and high-quality，new quality productive forces are gradually becoming a key driver for urban-rural integration development.This paper looks at the panel data of 180 cities in China from 2012 to 2021 to theoretically analyze and empirically test the impact of new quality productive forces on urban-rural integration.The research findings indicate that the level of urban-rural integration development has continuously improved from 2012 to 2021，with the eastern region leading the way.New quality productive forces show a fluctuating upward trend， with the central region exhibiting the best development momentum.Empirical results demonstrate that new quality productive forces have a significant positive impact on urban-rural integration development， with the mechanisms of action primarily reflected in promoting technological innovation， facilitating industrial transformation and upgrading， and optimizing resources allocation.Heterogeneity analyses reveals that the promoting effect of new productive forces on urban-rural integration is more pronounced in the eastern region with higher talent endowments and digital economy levels.Further research indicates that the impact of new productive forces on urban-rural integration prevents an inverted U-shaped relationship with dynamic effects over time.
