With the development of informatization and networking and the acceleration of urbanization, the breadth and depth of the impact of disasters have been deepened. While as an effective measure and essential guarantee in response for disaster, the inter-government coordination still has a lot of problems to address, such as unclear division of rights and responsibilities, blocked resource sharing, and unreasonable interest coordination. Based on these problems, this study proposes an emergency response strategy model considering information sharing and resource sharing according to evolutionary game theory, and analyzes the external factors (e.g., disaster characteristics, regional location) and internal factors (e.g., cooperation efficiency, rescue efficiency, interest coordination, etc.) that affect inter-government coordination from a micro perspective, as well as guiding effect of the construction of the vertical government information sharing platform on horizontal inter-government emergency coordination, so as to analyses and compare the strategy selection and evolutionary path of governments. The following results and policy suggestions can be obtained through the numerical analysis of case of the Guangdong-Hong Kong-Macao Greater Bay Area: 1) The information sharing platform promotes the efficiency of horizontal inter-governmental communication and coordination to some extent. 2) External factors have a significant impact on horizontal inter-governmental coordination. Besides, horizonal governments determine the coordination amount of relief supplies with overall consideration. 3) The form of interest distribution affects the horizontal inter-governmental coordination. Both sides need to comprehensively consider the disaster situation, relief benefits, costs and other factors to allocate supplies and benefits so that increase the possibility of collaboration. 4) The traceability of information sharing platforms can provide more reasonable incentives, subsidies and punishments for vertical governments, which promotes the horizontal inter-government division of power and responsibility and prevent from causing the failure of emergency management. It is suggested that the horizontal government should design an emergency plan and cooperation evaluation mechanism in the disaster preparation stage, formulate an appropriate benefit distribution mechanism based on internal and external factors, and conduct regular drills to improve the efficiency of cooperation. The vertical government should actively promote the construction of information sharing platform, use blockchain and other information technology to improve the sharing process and supervision system, and set up reasonable punishment and incentive mechanism, so as to promote the efficient response of disaster emergency under inter-government coordination.
