Abstract Based on entropy method, this paper uses panel data of 31 provinces in China (except Hong Kong, Macao and Taiwan) from 2011 to 2019 to describe resource and environmental carrying capacity from three dimensions of social carrying level (K1), pollution prevention capability (K2) and ecological restoration potential (K3), which is consistent with the goal of enhancing regional resources and environment carrying capacity. This paper also uses the Dagum Gini coefficient, kernel density estimation, and spatial econometric model to analyze spatial differences, dynamic feature and astringency of environmental bearing capacity of four regions in China which are east, west, middle, northeast parts. The spatial differences include withingroup variation, among groups variation and overall variation. The dynamic feature is described by Kernel density estimation, and astringency consists of σ convergence and β convergence, which is tested by Hausman, Wald, LM and LR model. It is concluded that: 1) The carrying capacity of Western China is greater than that in Eastern China, while the capacity in Western China also develops more rapid. 2) There are significant spatial differences in the resources and environment carrying capacity of these four regions, and the inter-group differences are the main sources. 3) There are significant differences in the dynamic evolution process of the absolute difference of resource carrying capacity in the four plates. 4) The characteristics of σ convergence and β convergence are different in the four tectonic plates. In Eastern China, there is no σ convergence in social carrying level, and there is no β convergence in pollution prevention capability, which puts great pressure on overall improvement of resources and environment carrying capacity.
