省域共同富裕水平测算及其时空演进

Measurement and Spatiotemporal Evolution of Common Prosperity Level in China at the Provincial Level

共同富裕是社会主义的本质要求,是中国式现代化的重要特征。文章根据共同富裕内涵、推动方向和路径,以2012—2020年中国31个省域为研究对象,构建了省域共同富裕水平的评价指标体系,并利用熵值法测算了中国31个省域的共同富裕进程。研究发现:2012—2020年中国共同富裕呈阶段性发展,全国共同富裕进程趋势积极向好。具体而言,从空间演进来看,共同富裕水平低的省域数量随时间推移明显减少,共同富裕水平中等的省域数量增长最快,共同富裕水平高的省域数量增长明显;从演进方向来看,共同富裕水平中等的省域发展方向由东南向西北方向发展,共同富裕水平高的省域首先以东部沿海省域向南拓展,2020年逐步向西北方向延伸;从地区差距来看,全国、中部地区、西部地区共同富裕离散程度存在扩大趋势,东部地区呈显著缩小的状态,除西部地区两极分化现象加剧外,其他区域极化现象均明显缓解;从长期演进趋势来看,随着时间推移,中国各省域均会转向高水平共同富裕。

Common prosperity is the essential requirement of socialism and an important feature of Chinese-style modernization.According to the connotation,direction and path of common prosperity,this paper takes 31 provincial-level regions of China from 2012 to 2020 as the research object,and constructs the evaluation index system of common prosperity level.It uses the entropy method to measure the process of common prosperity in 31 provincial-level regions of China.The results show that:1)From 2012 to 2020,China's common prosperity has shown phased development,the trend of the common prosperity process is positive in China.2)From the perspective of spatial evolution,the number of provincial-level regions with low-level-common prosperity decreases significantly over time,the number of provinciallevel regions with medium-level common prosperity increases the fastest,and the number of provincial-level regions with high-level common prosperity increases significantly.3)From the perspective of evolution direction,the development direction of the provincial-level regions with medium-level common prosperity develops from the southeast of China to the northwest of China,and the provincial-level regions with high-level common prosperity first expand to the south of China from the eastern coastal provinces,and gradually extend to the northwest of China in 2020.4)From the perspective of the regional disparities,the dispersion degree of common prosperity has an expanding trend in the whole country,the central region and the western region,while it has a significantly decreasing trend in eastern region.In addition to the intensified polarization in the western region,the polarization phenomenon in other regions has significantly eased.From the perspective of long-term evolution trend,all provincial-level regions in China will shift to a high-level common prosperity.
