Urban Lifeline Security Projects: Research on the Holistic Governance Model of Urban Public Security Empowered by Digital Technology

With the rapid advancement of urbanization, the density and vulnerability of urban lifeline networks are increasing, and urban lifeline security risks have become a major challenge to urban public security governance. The backward governance means and fragmented governance mechanisms cannot adapt to the complex emerging urban public security risks. Digital empowerment is considered to be a new solution for the holistic governance of urban lifeline security, but related research has only focused on a single scenario, a single risk type or a single risk management link. This study shifted from a single perspective to a holistic perspective and explored how to use digital technology to develop the urban lifeline security project from three levels, that is, overall methods, key supporting technology, and governance mechanism innovation, so as to enable a holistic governance model for lifeline security. Specifically, this study constructed the main processes and methods for constructing urban lifeline security projects, the key supporting technology system for the scenario-driven urban lifeline security project, and the overall governance mechanism for the urban lifeline security project. The case from Hefei, China, further verifies the effectiveness of urban lifeline security engineering. The contribution of this study is to promote the collaborative innovation and integrated application of engineering technology and governance mechanisms in the field of holistic governance of urban lifeline security.
