Abstract: Highlights•A modified security investment game model that integrates the subsidy policy in the insurance scenario is formulated.•Three novel subsidy policies against the PDPI (precaution and dynamic post-indemnity) insurance are proposed.•The effectiveness of proposed subsidy policies are studied from perspectives of the public and insurer.•A larger amount of subsidies degrades the performance of subsidy policies against risk precaution funds in some scenarios.•The dynamic allocation based subsidy policy can always work effectively while not reducing the profit of the insurer.
