Accurate Identification and Characteristic Analysis of Township Population Shrinkage from the Perspective of Dual Boundary:A Case Study of the Yellow River Basin
Taking the townships in the Yellow River basin as the research object and based on the data of the Sixth National Census,the Seventh National Census,spatial remote sensing and relevant economic and social statistical data,this paper proposes a shrinkage identification method from the dual perspectives of administrative boundary(broad sense)and economic boundary(narrow sense),so as to accurately define the population shrinkage of townships in the Yellow River basin,and then analyze the spatial pattern and characteristics of population shrinkage.The results show that:1)From 2010 to 2020,a serious shrinkage phenomenon occurred in the Yellow River basin,with 76.82%of the townships experiencing administrative boundary shrinkage and 45.65%experiencing economic boundary shrinkage.2629 townships experienced simultaneously two types of boundary shrinkage,which accounts for 36.42%.2)Shrinking townships show the uneven distribution characteristic,are mainly distributed in the northwest and east sides of the middle and upper reaches of the Yellow River,and basically form a concentrated and contiguous distribution trend,Henan Province accounts for the highest proportion of shrinking townships.3)From the perspective of spatial autocorrelation,shrinking townships have significant spatial agglomeration characteristics,and the number of townships in low-low agglomeration areas and high-high agglomeration areas accounts for 37.58%and 19.25%,respectively.4)Compared with non-shrinking townships,shrinking townships have a faster decrease in working-age population.The aging degree is more serious,the pressure for supporting the elderly is greater and the demographic dividend is smaller.5)The number of industrial enterprises,industrial enterprises above designated size,general stores and supermarkets in shrinking townships is much lower than that in non-shrinking townships,showing a difference in development.6)Shrinkage is more likely to occur in townships with smaller populations,the population shrinkage of townships in resource-based cities is more serious than that in non-resource-based cities.The population loss of townships within urban agglomerations is more serious than that of townships outside urban agglomerations.
