This study focuses on the application of digital technology in the renovation of public spaces in rural idle buildings, exploring its design methods and practical pathways. Taking Village X as the study village, the study analyzed its geographical scope, ecological environment, and public space composition. Through field survey methods, the current status of public space utilization in Village X was investigated on-site. Using various digital technologies, the renovation of public spaces such as recreational spaces and service facilities in Village X was achieved. Using methods such as the entropy weight method, the study analyzed the quality of life in different renovated areas of X Village and combined the geographic detector model to identify the core factors influencing quality of life. The survey of the current state of public spaces in X Village revealed that satisfaction ratings for recreational spaces, service facilities, landscape design, road conditions, and neighborhood connectivity were relatively low, indicating the need for further renovation. Under the renovation methods proposed in this paper, the comprehensive multifunctional evaluation values of public spaces in the main renovation areas of X Village ranged from 0.1068 to 0.1825, indicating a clustering effect in the degree of digital renovation. After digital renovation, the average quality of life in X Village was 0.446, with a Moran’s index of 0.515 and P < 0.05, indicating that the quality of life in X Village exhibits a significant spatial autocorrelation relationship. The impact of digital renovation of public spaces on living standards in X Village is the strongest, at 0.4419.
