Abstract: The report of the 20th National Congress of the Communist Party of China proposes that the construction of livable, business friendly, and beautiful countryside is a major strategic mission for comprehensively promoting rural revitalization at present. It is of great theoretical and practical significance to conduct in-depth researches on the construction level of livable, business friendly, and beautiful countryside. Based on the construction of a horizontal indicator system and the vertical and horizontal leveling method, this paper measures theconstruction level of livable, business friendly, and beautiful countryside in 31 provinces from 2011 to 2020, and the regional differences and dynamic evolution are revealed by using Dagum Gini coefficient, Kernel density, and Moran index. The findings showthat, firstly, during the sample period, the construction level of livable, business friendly and beautiful countryside in China is steadily increased, with the highest construction level in the eastern region and the fastest annual growth rate in the western region. Secondly, both intraregional and inter regional differences in the construction level are showing a downward trend, with the inter regional differences being the main cause of regional differences. Thirdly, in terms of time evolution, the absolute differences in the construction levels across the country and the three major regions are gradually decreased, but there has always been a significant gap between the leading and lagging provinces in the country and the eastern regions. Fourthly, in terms of spatial evolution, the aggregation mode mainly manifests as H-H aggregation and L-L aggregation, with only a small number of provinces completing the transition to the promotion or the radiation areas. Therefore, it is recommended that to further strengthen the construction of livable, suitable for work, and beautiful countryside from the three aspects, i.e., to fully activate various production factors, to actively promote regional coordinated development, and to implement policies tailored to different provinces.

Key words: livable, business friendly and beautiful countryside, vertical and horizontal leveling method, regional differences, dynamic evolution
