Core Viewpoint - Guangzhou has been selected as a pilot city for national data infrastructure, showcasing the "Guangzhou Plan" at the 2025 China International Big Data Industry Expo and receiving the pilot task book from the national authorities [1][7]. Group 1: Pilot Project and Framework - The selection as a pilot for national data infrastructure is based on the integration of "three ports" concept, with "data port" as the core hub for data circulation, complemented by "air port" and "sea port" for specialized data [1][5]. - The project aims to establish a benchmark for data infrastructure in the Guangdong-Hong Kong-Macao Greater Bay Area [1]. Group 2: Technical Validation and Collaboration - Guangzhou has completed key technical validations for cross-domain data circulation and has participated in national interoperability tests, achieving verification of high-speed network capabilities and completing 40 test items [3][4]. - Collaborations with various regions and companies, including Hebei, Wenzhou, and China Unicom, have been established to test cross-domain interoperability and validate the feasibility of the "Guangzhou Plan" [3][4]. Group 3: Data Resource Integration and Achievements - The "data port" has aggregated 75.2 billion public data entries, with a daily exchange volume of 294 million entries, involving over 80 ecosystem participants and creating 87 data products [6]. - The "air port" has integrated data from 12 entities, processing approximately 1.81 million data entries and establishing a trusted data space for transportation [6]. - The "sea port" has launched 287 service projects, processing over 150 million data entries and serving nearly 60,000 individual users, with over 250,000 queries [6]. Group 4: Future Directions - Guangzhou will focus on addressing common challenges in data utilization and circulation, accelerating the implementation of data infrastructure construction as per national directives [7].
