Resource-based regions support national economic development and are essential sources of basic energy raw materials. In the post-pandemic era, however, there practical situations to deal with, such as a fractured industrial chain, weaker structure, sharp reduction in benefits. Based on data collected from 68 cities China, 2010 2021, with 816 observations, this paper explores process resource-based China change toughness structure under impact COVID-19. The studies analyzes trends, toughness, spatial spillover effects. methods used Markov chain model Industrial Structure Advancement Index. By building Dubin model, effect regional development. It decomposes using partial differential based regression. results show that, during study period, comprehensive level industries was slowly improving tended stabilize after entering era. evolution an advanced is significantly heterogeneous among regions, each region has different toughness. COVID-19 reduced China’s regions’ structure. significant. Labor force, technology input, industrial-structure optimization have impacts neighboring regions. new management for more innovation. order achieve low-carbon, environmental protection, sustainable resources, realize rapid recovery cities, reduce pandemic, proposes expand supply improve allocation optimize direction, promote rational flow efficient aggregation various factors, enhance impetus innovation
