Excess delivery of agricultural chemicals seriously threatens the ecology and environment of agricultural areas and restricts the sustainable development of agriculture. The analysis of the environmental agrochemical Kuznets curve (EKC) adopting spatial econometric tools is limited. Therefore, this study adopted the spatial panel regression approach to analyze agricultural chemicals EKC Trois Gorges Reservoir Region (TGRR). The results show that (1) the two EKC curves of chemical fertilizer and pesticide of TGRR are inverted U-shaped, and there are 53.8% and 42.3% of counties / districts did not reach the Inflection point of the EKC for fertilizer and pesticide chemicals. (2) The CECs of TGRR agricultural chemicals are stable, and variables such as cultivated area and income disparity between town and country have an impact on the occurrence of the EKC inflection point. (3) There is spatial “mimicry and convergence” of agricultural chemicals among counties in the GRRT. 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 and economic development must be proposed.
