摘要:

建立系统韧性并提高应急能力,对应对灾害风险、统筹发展与安全意义重大。基于社会福利最大化的共同目标,本文从公共和私营部门合作应对灾害风险的角度出发,借助索洛经济增长模型,构建了一个整合经济增长和系统韧性的动态灾害风险管理新模型,该模型包括两组正负反馈回路,不仅可用于分析公私双方的防灾投入与经济增长及系统韧性之间的权衡关系,还可进一步用于分析社会福利演变过程以及评估防灾政策效果。通过理论分析,本文给出:(1)无灾害情况下的系统最优资本水平和社会福利水平;(2)灾害发生情况下的最优投资率、防灾投入、系统韧性和社会福利水平;(3)考虑灾害概率的投资率、防灾投入和系统韧性水平的优化决策模型。最后,本文通过算例进一步验证与讨论了最优决策及其与相关参数的变化关系,为公共和私营部门共同进行灾害管理以实现社会福利最大化提供了决策依据。

Abstract:

In recent years, the Chinese government has proposed the integration of development and security to build a safer and more resilient China. Strengthening emergency response capabilities and enhancing system resilience are critical for effective disaster risk management. From the perspective of maximizing social welfare through public-private partnerships (PPP), the centralized decision-making process between the public and private sectors in addressing disaster risks is explored, particularly the trade-offs between disaster preparedness investment, economic growth, and system resilience. By integrating the Solow economic growth model with system resilience theory, this paper develops a new dynamic disaster risk management model. The model incorporates two positive feedback loops and two negative feedback loops, enabling the evaluation of social welfare and analysis of policy effects. The main results show that: (1) The optimal system capital level and social welfare in the absence of disasters; (2) The optimal investment rate, disaster preparedness investment, system resilience, and social welfare level in the event of a disaster; (3) An optimization model for maximizing social welfare under disaster probability, including the investment rate, disaster preparedness investment, and system resilience level. The solutions to the objective function are analyzed and numerical simulations are conducted to explore the impact of key parameters on optimal decision-making. The results offer valuable insights for both the public and private sectors in collaboratively managing disaster risks, enhancing system resilience, and maximizing social welfare. The contribution of this study lies in providing a framework that integrates economic growth and resilience management, offering theoretical support for policymakers to optimize disaster preparedness strategies.

Key words: PPP, disaster preparedness investment, resilience, economic growth, disaster risk management
