考虑供应链信任演化3个不同阶段,研究供应链信任稳定演化策略。针对传统博弈的局限性,从约束机制不健全和约束机制健全两个层面进行分析,将企业选择信任的额外收益、单方面信任成本、单方面不信任额外收益、单方面不信任代价和单方面信任额外补偿引入到演化博弈矩阵中,利用演化博弈理论分析各阶段的稳定状态。为验证模型的有效性和可行性,通过数值分析,研究模型的演化动力变化,得出相应的系统相图。研究结果表明,供应链信任策略值的概率大于0.75时,合作达到稳态,供应链整体收益最大;约束机制不健全下的稳定演化策略明显优于传统博弈下的稳定演化策略,但是约束机制不健全,企业的稳定演化策略未必都是信任;供应链企业间需要健全约束机制,当约束机制健全时,信任是企业最终策略选择。 相似文献

C2C交易中第三方信任机制作用的实证分析 总被引:1,自引:0,他引:1
提出了C2C市场中第三方信任机制作用模型,这些机制包括反馈系统、Escrow服务、C2C中介以及电子商务法律法规.通过网上问卷调查,收集到215份有效数据,并采用SPSS与PLS Graph进行统计分析,检验了量表的信度、效度与模型假设.结果表明Escrow服务、C2C中介、反馈系统显著影响消费者对卖方信任的建立,没有发现法律法规对信任的显著作用.此外,信任显著影响感知风险与交易动机. 相似文献

信任作为一种人际互动的简化机制,其理性一非理性特征、动态演化特征受到诸多学者的关注,关系信号理论以人际关系信号为切入点提供了理解信任的新视角。本文介绍了关系信号理论的假设和心理学基础,阐明了关系信号理论对信任理性一非理性特征的解释,并分析关系信号理论对信任动态性的解释。本文认为关系信号理论以过程理性的观点对信任中的计算理性和社会理性动态解释,有利于信任一元模型的建立,同时也指出了目前关系信号理论的局限性和未来发展远景。 相似文献

Trust widely works in supply chain practices and deeply affects supply chain decisions. Full trust in transactions and inaccurate demand forecasts are most likely to lead to biased decisions and low supply chain performances. Therefore, we propose a trust updating model to quantify decision-maker’s trust. The model presents the variation of trust over time and is helpful to evaluate decision-maker’s trust level in each transaction. In the model, a coordination mechanism with contract is designed to mitigate each supply chain partner’s ordering risk. Optimal order strategies of both manufactures and retailers in a supply chain under a bidirectional option contract are analysed in this paper. We find the manufacturer’s optimal production quantity is positively affected by penalty price in the contract and its bounds are given by simulation analysis. Our findings in this paper indicate that the proposed coordination mechanism with bidirectional option contract is profitable to all supply chain partners in long-term transactions. Meanwhile, the coordination mechanism helps the supply chain partners to catch up with marketing fluctuations and enhances the supply chain trust and partnerships. Finally, some simulation experiments are employed to obtain more observations. 相似文献

In networked mobile commerce network transactions, trust is the prerequisite
and key to a smooth transaction. The measurement of trust between entities involves
factors such as transaction amount, transaction time, personal income of consumer
entities and their risk attitude towards trust, etc., so it is difficult to accurately calculate
quantitatively. In order to find out the essential characteristics of this trust relationship,
based on the research background of mobile commerce in the mobile network
environment, a dynamic trust mechanism is proposed through the research of trust in the
mobile network environment, trust influencing factors and trust mechanism. The
calculation model of mobile interactive services based on mobile service business
transactions. The model calculates feedback credibility through feedback deviation and
feedback robustness, and combines transaction context factors and trust mapping
mechanism to judge the seller’s credibility. This model better reflects the degree of
influence of subjective factors such as personal preferences and risk attitudes on trust
calculations, And the sensitivity of trust algorithms and transaction attributes has been
greatly improved. After a large number of experiments and theoretical analysis, this
mechanism provides an effective explanation for solving the problem of network trust
computing. and provides valuable new ideas for the study of secure transactions in the
mobile Internet environment. 相似文献

A P2P computing environment can be an ideal platform for resource-sharing services in an organisation if it provides trust mechanisms. Current P2P technologies offer content-sharing services for non-sensitive public domains in the absence of trust mechanisms. The lack of sophisticated trust mechanisms in the current P2P environment has become a serious constraint for broader applications of the technology although it has great potential. Therefore in this work an approach for securing transactions in the P2P environment is introduced, and ways to incorporate an effective and scalable access control mechanism - role-based access control (RBAC) - into current P2P computing environments has been investigated, proposing two different architectures: requesting peer-pull (RPP) and ultrapeer-pull (UPP) architectures. To provide a mobile, session-based authentication and RBAC, especially in the RPP architecture, lightweight peer certificates (LWPCs) are developed. Finally, to prove the feasibility of the proposed ideas, the RPP and UPP RBAC architectures are implemented and their scalability and performance are evaluated 相似文献

目的 考虑消费者对环保标签的信任度和绿色意识,探究利他偏好对制造商和零售商决策的影响。方法 构建由生产自贴环保标签型绿色产品制造商和零售商组成的Stackelberg博弈模型,分析制造商利他偏好的作用机制,然后采用数值分析方法对决策结果进行对比。结论 消费者对环保标签信任度的提升和制造商利他偏好的增强有助于提升绿色努力水平和绿色供应链总利润;当制造商利他偏好强度过大时,制造商的利润会随着消费者信任度的增加而减少,可能出现负值,引起供应链失衡;制造商利他偏好强度和消费者信任度越大,对制造商效用的提升效果越明显。 相似文献
