Abstract: As the standard of good governance and good governance in the new era of national governance, citizen's sense of gain is an extremely accurate and vivid reflection of the people's strong expectation and value expression for a better life. In the context of the new era in which efficient markets and productive governments form powerful synergies, it is clear that government and market have an important impact on citizen's sense of gain. Through the analysis of 3317 survey data, the research finds that social capital in the logic of benefiting people's livelihood and government trust in the logic of solving people's livelihood have a positive impact on the sense of gain, and digital government can effectively regulate the impact of social capital and government trust on the sense of gain. The above conclusions reveal the intrinsic relationship between government market elements and sense of gain, enrich the academic perspective on the co-evolution theory of government market, and have practical implications for improving citizens' sense of gain.
