Research on cross-organizational integration and sharing strategies of digital health resources in the context of cloud platforms.

With the rapid advancement of information technology, cloud platforms have emerged as pivotal infrastructure for the storage, management, and sharing of digital health resources, playing a crucial role in the digital health landscape. This paper constructs a framework based on the integration mechanism of digital health resources in the cloud platform environment, and uses the differential game method to deduce how to achieve cross-organizational integration and efficient sharing of digital health resources, and proposes corresponding optimization strategies and coordination mechanisms. It is found that: (1) In the context of decentralized decision-making under a cost-sharing-absent contract, individual entities formulate strategies based on their respective marginal benefits. The dynamic interplay of these strategies unexpectedly yields positive ramifications. (2) Adopting master-slave decision-making under the cost-sharing contract can significantly enhance the system's resource sharing effect, but the incentive subsidy of the cloud platform needs to be kept in a moderate range. (3) The centralized decision-making framework within the context of collaborative control embodies sophisticated optimal decision analysis, while also illuminating the mechanisms through which participating entities facilitate the integration and optimization of resources within digital health systems. The theoretical contribution of this study is to provide strategic guidance for the synergistic cooperation between the government and academic research organization in the context of the cloud platform, and its practical significance is to guide the digital health system to achieve sustainable development.
