Abstract: Regular usage of the “Health Code”, a social governance and emergency management technology spawned by COVID-19 pandemic, not only relates to the life cycle of this technical tool, but also tests the feasibility and effectiveness of such data-based innovation for social governance in the post-pandemic era. Taking the Technology Acceptance Model (TAM) as a reference, a model of intention to regularly use the “Health Code” was constructed. The empirical results showed that people’s intention to regularly use the “Health Code” was accompanied by a "benefit-risk" calculus, and the results would change with the weakening of technology effectiveness, the intervention of data owners, and the recurrence of crisis situations. The theoretical and practical implications were then provided.

Key words: “Health Code”, Regular Usage, Social Governance, Emergency Management, Data Governance
