The Chinese Government has played an important role in organizing the evacuation of typhoon disasters, and in-depth analysis of individual behavioral decisions is a prerequisite for adopting an effective emergency organization plan. Existing evacuation plans only consider how the Government issues the early warning and organizes the mandatory evacuation, but does not formulate effective policies to improve the efficiency of self-evacuation of evacuees and lacks the understanding of individual evacuation decision-making. Using game-based theory in a small-world network context, we build an evolutionary game model of evacuation decision diffusion between evacuees in the context of a complex network. The model simulates the effects of guaranteeing the evacuation order and providing material supplies on the evacuation decision diffusion in a small-world network in China. The results showed that various levels of policy-implementation led to different rates of evacuation. As the cost-reduction of the evacuation process increased, the evacuation response rate in the social system increased. In contrast, as the rate of reducing the non-evacuation cost decreased or the cost-reduction rate of non-evacuation increased, the evacuation response rate in the social system decreased. The study findings provided insights on emergency planning and the effectiveness of their implementation in social networks, which can be used to improve evacuation policy.
How to provide financial support efficiently is becoming an essential way for military enterprises to take the strategy of Civil-Military Integration (CMI) in China. In this paper, we used the evolutionary game theory to build a model for military enterprises to choose the approach of the CMI with financial support. After derivation and simulation of the model, the results showed that the profit and cost from the CMI or the financial support changes could cause the different evolutionary stable states (ESS). Setting the financial support degree in a relevant range could encourage firms to participate in the CMI and reduce the spillover. Besides, the initial proportion of military enterprises that choose the CMI could affect and predict the trend of future development, which provides a reference for policy-makers.
