Abstract: Accelerating the circulation and utilization of data to fully unleash its value relies on robust data infrastructure. This paper integrates domestic and international research foundations and current practices in data circulation and utilization, deeply analyzing the new demands that data elements place on infrastructure. It summarizes the latest trends in global infrastructure development, and based on this, addresses practical challenges such as trustworthy data supply, efficient processing, active circulation, and practical application. This paper proposes a comprehensive framework for data circulation and utilization, consisting of "one computational support base, two types of resource-coordinated scheduling, a three-tier efficient circulation system, and four-dimensional innovative integration demonstrations." It then provides specific recommendations for implementation at different stages, focusing on strengthening foundational support, optimizing circulation systems, and improving application ecosystems. These insights aim to offer valuable references for accelerating data infrastructure development and promoting efficient data circulation and utilization in the new era.
