The identification of economic resilience levels and its obstacle factors in the counties of the Yellow River Delta was es-sential for promoting high-quality county development.Taking the Yellow River Delta county as the research object,this paper con-structed the dynamic two-way evaluation index system of county economic resilience in this area by DPSIR model and two-way evalu-ation index system method,and analyzed the spatio-temporal differentiation characteristics and obstacle factors of economic resilience from 2011 to 2020 through the entropy method,Dagum Gini coefficient,ESDA and obstacle degree model.The results showed that:①The economic resilience of the county as a whole showed a fluctuating upward trend from 2011 to 2017,followed by a decline and subse-quent upward trend from 2018 to 2020.②The economic resilience of each county unit exhibited a consistent upward trend,accompanied by a gradual widening of the gap between their levels of economic resilience.However,there was no significant alteration in the ranking order of economic resilience.③There was no significant disparity in the spatial distribution of economic resilience,with a transition ob-served from random dispersion to spatial concentration,and the resilience level in the northwest generally exhibited lower values com-pared to that in the southeast,with a predominant medium mean value observed at each time point.④The Gini coefficients of economic resilience were all below 0.2,indicated a high level of average economic conditions in this region.The sources of variation in economic resilience were firstly the inter-regional,followed by the hyper-variable density,and finally the intra-regional.⑤The main obstacle factors of each group were similar,primarily concentrated within the criterion layer of resources level,wealth disparity,technological ad-vancement and consumption potential.
