Accelerating the development of domestic and foreign trade integration is an intrinsic requirement for building the new development para-digm and promoting high-quality development,and plays an important role in promoting economic development,expanding domestic demand and sta-bilizing enterprises.The index system of domestic and foreign trade integration level is constructed from three dimensions of enterprise qualification,market environment and policy support.Based on the entropy method of weighting,this paper meas-ures the domestic and foreign trade integration level of 30 provinces in China from 2012 to 2021,and analyzes the distribution dynamics and regional differences of domestic and foreign trade integration level by using the kernel density estimation,Markov chain,spatial Markov chain,β-convergence,and Dagum Gini coefficient in each region.It is found that:(1)the integration level of domestic and for-eign trade in the national,eastern and western regions is characterized by decentralized agglomera-tion,while the integration level of domestic and foreign trade in the central and northeastern regions is characterized by aggregated agglomeration.(2)Provinces with different integration level of domestic and foreign trade have the greatest proba-bility of maintaining their original levels in the next stage,i.e.,there is a'club convergence'charac-teristic.The transfer between different levels has significant spatial dependence,with low-level provinces hindering the growth of neighboring prov-inces'integration levels of domestic and foreign trade,while high-level provinces show positive pulling effects on neighboring provinces'integration levels of domestic and foreign trade.There is condi-tional β-convergence in the integration level of domestic and foreign trade in the country and the four major regions,and the central region with a lower level converges faster to a higher level.(3)The overall difference in the integration level of domestic and for-eign trade shows a small decreasing trend,and the inter-group differences in the four major regions are the main source of regional differences,followed by intra-regional differences,with the smallest hyper va-riance density.The findings of this article provide a reference basis and feasible path for steadily advancing the development of China's integration of domestic and foreign trade and accelerating the con-struction of a new development pattern.
