Abstract: 【Purpose/significance】Providing basic public services to the public as public goods in a tabulated and standardized way is an innovation in the development of public services from concept to system, which also provides a new perspective for exploring the open use of public data in China【. Method/process】Combined with public "product service" logic, through the technology acceptance model and service scenario theory, a three-dimensional analysis framework of influencing factors of public data utilization effect in⁃ cluding public data quality, public data platform and public data service is constructed. Based on 26 local public data websites, the analysis framework of influencing factors is configured by using qualitative comparative analysis. 【Result/conclusion】 The impact of public data open utilization on configuration results can be summarized into three paths: practical driven, scenario experience, and full chain demand. Among them, public data service quality perception and public data service interaction process variables are necessary conditions.【 Innovation/limitation】 The research shows that it reveals what factors can affect the user's data resource utilization effect and effective path on the public data platform, and provides feasible ideas for improving the management level of public data resources under the digitalization process.
