Based on a comprehensive literature survey, the constructs of the cybersecurity information sharing ecosystem have been defined in detail. Using this ecosystem, the interrelationships among the stakeholders with respect to cybersecurity information sharing are analyzed, the value parameters are determined, the value functions are defined, and the values obtained by the stakeholders through simulation are calculated. Furthermore, it is investigated whether the stakeholders involved in this ecosystem can create sufficient value to sustain in the market. The outcome of this research includes an economic model for evaluating the value creation and distribution among the stakeholders. This model is a critical step forward to better align the values (i.e., utilities and profits) of stakeholders. The simulation results of the model show that end users are the main source of value generation. Cybersecurity solution providers and cybersecurity information providers get benefits from a growing installed base of end users. However, in saturated markets, there is a risk of un-sustainability of the ecosystem, as the cost of cybersecurity solutions and cybersecurity information cannot be recovered through their fees. The simulation model and the findings of this study can help business managers to make better decisions related to business strategies, sustainability, and pricing schemes for cybersecurity solution and cybersecurity information. Moreover, a working cybersecurity information sharing ecosystem is essential for the adoption of cloud computing and, especially, edge computing. It allows capturing, disseminating, and aggregating cybersecurity information from a large number of computing devices and computing providers reliably and accurately.

基于全面的文献调查，详细定义了网络安全信息共享生态系统的构建。利用这个生态系统，分析利益相关者之间在网络安全信息共享方面的相互关系，确定价值参数，定义价值函数，并计算利益相关者通过模拟获得的价值。此外，调查参与该生态系统的利益相关者是否能够创造足够的价值来维持市场。这项研究的结果包括一个经济模型，用于评估利益相关者之间的价值创造和分配。该模型是朝着更好地协调利益相关者的价值（即公用事业和利润）迈出的关键一步。模型仿真结果表明，终端用户是价值产生的主要来源。网络安全解决方案提供商和网络安全信息提供商从不断增长的最终用户安装基础中受益。然而，在饱和的市场中，生态系统存在不可持续的风险，因为网络安全解决方案和网络安全信息的成本无法通过其费用收回。本研究的模拟模型和结果可以帮助业务经理在网络安全解决方案和网络安全信息的业务战略、可持续性和定价方案方面做出更好的决策。此外，一个有效的网络安全信息共享生态系统对于采用云计算，尤其是边缘计算至关重要。它允许捕获、传播、
