中国"双循环"新格局发展水平的时空分异及动态演进OA北大核心CHSSCDCSSCICSTPCD

Based on the data of 30 provinces in China from 2003 to 2020,this paper constructs an indicator system to mea-sure the development level of China's new pattern of"dual circulation"from the three dimensions of internal circulation,exter-nal circulation and internal and external integration,and then uses Dagum Gini coefficient decomposition method,Kernel density estimation method,Markov chain transition matrix and Moran's Ⅰ to reveal the regional difference,dynamic evolution trend and spatial correlation of the new pattern development level of"dual circulation".The results are shown as follows:The development level of China's new pattern of"dual circulation"and the level of the three subsystems are rising as a whole.There are obvious regional differences in the development level of the new pattern of"dual circulation",which mainly come from the differences among regions,and the difference between the east and the west is the most prominent.The absolute difference of the develop-ment level of the new pattern of"dual circulation"is reduced in the fluctuation,and the polarization phenomenon of internal and external integration level is obvious.The development level of the new pattern of"dual circulation"has the characteristics of"club convergence"and a certain degree of Matthew Effect,and has distinct spatial agglomeration characteristics.
