标题： Internet of Things Platform Service Supply Innovation: Exploring the Impact of Overconfidence

摘要： 本文通过构建博弈模型，探讨了制造商的过度自信在其与物联网（IoT）环境中平台协同创新中的影响。 研究发现，在基于使用量和收益共享的合同中，制造商和平台的创新投入、利润水平和定价策略均显著受到非隐私敏感客户比例的影响，并随着该比例的上升而同步增长。 在基于使用量的合同中，适度的过度自信会激励制造商增加硬件创新投资并提高整体供应链收益，但可能导致平台减少软件创新；在收益共享合同中，过度自信对硬件创新和定价的激励作用更强，而平台的软件创新则根据分成比例呈非线性变化。 比较制造商在有无过度自信情况下的决策差异表明，在给定合同下，适度的过度自信可以导致供应链的帕累托改进。 本文为理解物联网供应链中制造商与平台之间的复杂互动提供了新视角，并为实际商业决策提供了理论支持和实践指导。 显示英文摘要

摘要： This paper explores the impact of manufacturers' overconfidence on their collaborative innovation with platforms in the Internet of Things (IoT) environment by constructing a game model. It is found that in both usage-based and revenue-sharing contracts, manufacturers' and platforms' innovation inputs, profit levels, and pricing strategies are significantly affected by the proportion of non-privacy-sensitive customers, and grow in tandem with the rise of this proportion. In usage-based contracts, moderate overconfidence incentivizes manufacturers to increase hardware innovation investment and improve overall supply chain revenues, but may cause platforms to reduce software innovation; under revenue-sharing contracts, overconfidence positively incentivizes hardware innovation and pricing more strongly, while platform software innovation varies nonlinearly depending on the share ratio. Comparing the differences in manufacturers' decisions with and without overconfidence suggests that moderate overconfidence can lead to supply chain Pareto improvements under a given contract. This paper provides new perspectives for understanding the complex interactions between manufacturers and platforms in IoT supply chains, as well as theoretical support and practical guidance for actual business decisions.
