Research on the spatiotemporal evolution and influencing factors of common prosperity in China

Since 2012, China's economic growth rate has been much higher than the world average; its economic aggregate ranks second in the world, people's living standards have risen significantly, and absolute poverty has been historically eliminated, laying a solid foundation for solid promotion of common prosperity. However, China is still in the primary stage of socialism, and the problem of unbalanced and inadequate development has not been fundamentally solved. It is urgent to monitor the status of common prosperity construction in all regions. By constructing an evaluation index system of common prosperity, this paper uses spatial correlation analysis model and geographically weighted regression model to assess the comprehensive development level of common prosperity quantitatively, reveal the spatiotemporal evolution characteristics and analyze the main influencing factors. The results show that the comprehensive development level of China's common prosperity has been continuously improved. It gradually presents a spatial distribution pattern with Beijing-Shanghai as the development pole and the eastern coastal area as the highland, and there is a significant positive spatial correlation, but the local spatial heterogeneity has increased. The development level of common prosperity is affected by multiple factors, and the increase in per capita GDP is the leading factor in promoting common prosperity. Therefore, we should focus on promoting high-quality economic development, coordinated regional development and expanding middle-income groups, so that all people can enjoy the fruits of reform and development and ultimately achieve common prosperity.
