[Purpose/significance] With the rapid development of technologies such as the Internet, cloud computing,big data and artificial intelligence, the impact of digital transformation on human happiness has gradually emerged.This paper aims to explore the conceptual connotation of digital happiness and construct a standardized evaluation in⁃dex system to provide theoretical basis and practical guidance for understanding and improving digital happiness.[Method/process] Through literature research, interview, qualitative text analysis and other methods, the evaluation in⁃dicators of digital happiness were comprehensively extracted, and the weight of each indicator was determined by the analytic hierarchy process, and a digital happiness evaluation index system was constructed. At the same time, based on this system, the digital happiness level questionnaire is designed, using the fuzzy comprehensive evaluation method to evaluate the current situation of the public's digital happiness. [Result/conclusion] Three main dimensions of digi⁃tal happiness were proposed in this paper: the positive use experience of digital products and services, the positive psy⁃chological function in the use of digital products and services, and the positive social mentality in the use of digital prod⁃
ucts and services. The public's digital happiness suffers from a lack of security, autonomy, and inclusion in digital soci⁃ety, which can be improved by strengthening digital society governance, optimizing product design, and enhancing user capabilities. This paper provides a new theoretical framework and assessment tool for evaluating and improving digital happiness, which can guide the governance of digital society and product design optimization.
