The digital-intelligent transformation of public cultural service governance is an imperative of our times and the essential path to achieving high-quality development in public cultural services through digital and intelligent technologies. Based on the "value-space-technology" triad of the digital-intelligent transformation of public cultural service governance, this paper constructs an analytical framework for its logical implications, risk type identification, and governance pathways. It clarifies that this transformation encompasses three-tiered logics: a value logic shifting from supply-demand separation to co-creation of value; a spatial logic reinforcing data spatial justice and integrated urban-rural spatial planning; and a technological logic advancing from digitization to digital-intelligence. It further identifies the risks existing in the digital-intelligent transformation of public cultural service governance in the new era, mainly manifesting as three types of risks: value risks such as ethical misconduct and algorithmic bias; spatial risks including regional spatial fractures and disorder in data space; and technological risks encompassing tool-driven alienation and system security challenges. To enhance the effectiveness of digital-intelligent governance in public cultural services, efforts should focus on: addressing value risks through data ethics reshaping and algorithmic bias correction; addressing spatial risks by strengthening regional spatial justice and building trustworthy data spaces; addressing technological risks via adaptation of digital-intelligent technology alienation and reinforcement of system resilience. These measures will promote the high-quality development of the digital-intelligent governance of public cultural services.
