企业应急物资轮换更新行为与政府监管博弈分析

政府作为社会安全和社会福利保障的责任者,需要监管企业合规储备和轮换更新应急物资与设备的行为,但常常因为受制于企业储备信息不透明而导致监管效果不理想.本文针对应急物资周期性轮换更新这一敏感问题,建立了政府和企业的博弈模型,分析了一类质量或性能随时间下降的应急物资和设备按期轮换更新行为的监管策略,采用基于经验学习的强化学习算法求得政企博弈均衡解.算例分析结果验证了经验学习方法解决这一类问题(道德风险问题)的有效性.通过对比分析不同社会损失水平下的企业轮换更新行为和政府监管模式,进一步提出了相应的应对措施,从而对于这一问题的有效解决,提供了较好的管理启示.

Game analysis of enterprises' replacement of emergency supplies and government's monitoring

Government, who has a primary stake in social safety and welfare, undertakes the task of monitoring enterprises to make sure that they reserve and replace emergency supplies and equipment as required. Nevertheless, the reality is unsatisfactory, which is caused by the hidden information about the reserves' quality and performance. This paper considers a kind of emergency supplies and equipment that are needed to be replaced periodically to guarantee their usability and availability. A government-enterprise game model is established to analyze the enterprise's shirking behaviors and the government's monitoring strategies. The experience based equilibria are generated from a reinforcement learning algorithm. Results demonstrate the effectiveness of utilizing the experience-learning method to solve this kind of moral hazard problem. This study further puts forward managerial implications by analyzing enterprise's replacement strategies and government's monitoring patterns when the enterprise faces different levels of social losses.
