Strengthening the social public service system is a crucial measure in ensuring and enhancing people's livelihood. Studying the temporal and spatial evolution of public services during the 13th Five-Year Plan period is of great practical significance for the national and local governments to further enhance the policy system of public services. Using panel data from 21 cities of Sichuan Province, analysis techniques including entropy weight TOPSIS were used to examine the temporal and spatial evolution of the province's basic public service level. The results showed that during the "13th Five-Year Plan" period, Sichuan Province's basic public service level increased steadily, although there were wide disparities between regions and the overall trend showed expansion and bipolarization.
