Excess deliveries of agricultural chemicals seriously threaten the ecology and environment of agricultural areas and limit the sustainable development of agriculture. The analysis of the environmental agrochemical Kuznets curve (EKC) by adopting spatial econometric tools is limited. Therefore, this study adopted the spatial panel regression approach to analyze agricultural chemicals EKC Three Gorges Reservoir Region (TGRR). The results show that (1) the two EKC curves of chemical fertilizers and pesticides of TGRR are inverted U-shaped, and there are 53.8% and 42.3% of counties / districts did not reach the point inflection of the EKC with respect to chemicals. fertilizers and pesticides. (2) The EKCs of TGRR agricultural chemicals are stable, and variables such as cultivated area and urban-rural income disparity impact the occurrence of the EKC inflection point. (3) There is spatial “mimicry and convergence” of agricultural chemicals among counties in the TGRR. The results indicate that the ecological and environmental situations of agriculture in the RBMT require urgent attention. Countermeasures aimed at reducing the contradiction between ecological development and economic development should be proposed.
