The panic buying behavior under public health emergencies will lead to many adverse consequences, such as material waste, price fluctuation and uneven distribution of epidemic prevention materials, which will pose a threat to the social stability and economic development. In this paper, we construct a tripartite game model to explore the strategic choices of the public, merchants and the government in order to effectively respond to the panic buying behavior in the epidemic. The results demonstrate that: (1) Eight evolutionary stable strategies emerge in the panic buying events. The worst scenario can be improved by adjusting some relevant parameters. (2) The probability of the public choosing the strategy of “not involving in panic buying” depends on the potential benefits and losses of snapping up, rather than the extent of price rising. (3) The probability of merchants choosing the strategy of “not bid up price” depends on the intangible benefits. (4) The probability of the government choosing the strategy of “active supervision” depends on the supervision costs and government credibility, rather than the amount of fines. In addition, strategic suggestions to mitigate panic buying behavior are put forward from the perspective of each stakeholder. 相似文献

We consider the competition among quantity setting players in a linear evolutionary environment. To set their outputs, players adopt, alternatively, the best response rule having perfect foresight or an imitative rule. Players are allowed to change their behavior through an evolutionary mechanism according to which the rule with better performance will attract more followers. The relevant stationary state of the model describes a scenario where players produce at the Cournot‐Nash level. Due to the presence of imitative behavior, we find that the number of players and implementation costs, needed to the best response exploitation, have an ambiguous role in determining the stability properties of the equilibrium and double stability thresholds can be observed. Differently, the role of the intensity of choice, representing the evolutionary propensity to switch to the most profitable rule, has a destabilizing role, in line with the common occurrence in evolutionary models. The global analysis of the model reveals that increasing values of the intensity of choice parameter determine increasing dynamic complexities for the internal attractor representing a population where both decision mechanisms coexist. 相似文献

将区块链技术应用于产业技术创新联盟信息共享领域,可解决联盟信息共享安全问题,提高联盟主体信息共享意愿,加深信息共享程度,进而提升联盟信息共享效率。使用演化博弈方法,构建产业技术创新联盟企业和学研两方的信息共享博弈模型,并通过Matlab仿真对影响双方信息共享决策的政府与区块奖励、惩罚力度、边际成本、风险系数5项因素的影响结果与演化逻辑进行具体分析。结果表明,与传统产业技术创新联盟信息共享过程相比,区块链技术的应用对其共享过程中的各项因素的关键参数值产生了较大影响,更容易推动双方实现均共享的理想均衡状态,但各因素的影响程度不同。有条件的联盟应致力于区块链技术与联盟信息共享网络的融合工作,根据实际情况制定合适的因素组合协同策略,促进联盟的可持续高速发展。 相似文献

Some models in evolutionary economics rely on direct analogies to genetic evolution, assuming a population of firms with routines, technologies, and strategies on which forces of diversity generation and selection act. This narrow conception can build upon previous findings from evolutionary biology. Broader concepts of evolution allow many or just one adaptive entity, instead of necessarily requiring a population. Thus, an institution or a society can also be understood as an evolutionary entity. Both the narrow and broad approaches have been extensively used in the literature, albeit in different literature traditions. I provide an overview of the conception and development of both approaches to evolutionary modeling, and argue that a generalization is needed to realize the full potential of evolutionary modeling. 相似文献

为改善重大水利工程项目决策社会稳定风险评估中公众参与现状,从社会稳定风险评估3个主要利益主体——中央政府、地方政府与公众不同的利益诉求出发,运用演化博弈模型,探讨在不同利益诉求的相互作用下影响地方政府与公众在社会稳定风险评估中策略选择的因素。研究发现,当公众受到的损失大于参与付出的成本时,双方稳定均衡状态均表现积极,反之,双方可能均表现为消极或积极这两种截然不同的状态。基于此,分析了中央政府对地方政府和公众在社会稳定风险评估博弈中策略选择的影响。最后,提出应加大对地方政府的支持、规范公众参与相关制度、加大教育培训及宣传力度、创新公众参与方式几项政策建议。 相似文献
