EVOLUTION AND INFLUENCING FACTORS OF THE DUAL SPATIOTEMPORAL PATTERN OF POPULATION CONTRACTION AND AGING:A CASE STUDY OF HEILONGJIANG PROVINCE
The authors use Pearson correlation analysis,Dagum Gini coefficient,GTWR model and grey pre-diction model and other methods,based on the national population census data in 2000,2010 and 2020,tak-ing Heilongjiang province,which has a large population contraction and a high level of aging,reveal the spatio-temporal coupling relationship between the two,and analyze the factors influencing population aging,Predict population size and aging development trend.Research shows that:1)Over the past 20 years,the population size has undergone an evolutionary process from slow growth to mild contraction to severe and severe contraction.2)The overall level of population aging shows a gradient upward trend from adult type Ⅰto elderly type Ⅰ to elderly type Ⅲ.3)Both municipal and county-level units exhibit a highly positive correla-tion between population contraction and population aging growth.4)The migration rate,elderly population base,per capita education years,mortality rate,and per capita GDP have a positive impact on the level of population aging.5)In the next decade,the population size of the region will continue to decline,and the level of population aging will be accelerating.
