Evolution Analysis of Large-Scale Spatiotemporal Configuration of Provincial Birth Rate in China

Population issues affect economic and social development. Solving population problems requires long-term regulation and implementation of effective measures, so it is necessary to have an accurate understanding of the China’s population. This paper uses spatial statistical methods to reveal the static spatial distribution and dynamic evolution of China’s birth rate more comprehensively. The research period is from 1978 to 2018, with a time span of 40 years. The result is the birth rate of each province in China has a non-random distribution in space, gradually decreasing from west to east. The birth rate shows a positive spatial aggregation in China’s provinces with an overall upward trend. Spatial stratified heterogeneity among the four regions of east, central, west and northeast shows an overall increasing trend. From the local aggregation characteristics, it can be seen that the HH aggregation is mainly in the western region and the central-southern region, and the LL aggregation is mainly in the northeast region. The HH agglomeration areas gradually migrated from the western region to the central-southern region.
