Core Viewpoint - The core objective of China's data infrastructure is to address issues related to data supply, circulation, and utilization while ensuring data security, aiming for a system where data can be effectively supplied, circulated, utilized, and secured [3][6]. Group 1: Data Infrastructure Goals - The primary goal is to resolve the existing problems of data being "unable to circulate, slow to flow, and poorly utilized" [3]. - China's data infrastructure is defined as a new type of infrastructure that provides services for data collection, aggregation, transmission, processing, circulation, utilization, operation, and security [3]. Group 2: Effectiveness Indicators - The effectiveness of data infrastructure can be measured by the volume of data in circulation; significant platforms like Didi, Meituan, and Ctrip demonstrate effective data infrastructure with billions of users [4]. - The second indicator is the security of the data circulation process, which is crucial for ensuring efficient and trustworthy data flow [5]. Group 3: Key Technologies - Six key technology routes have been identified to ensure both data circulation and security: blockchain technology, privacy computing technology, data networking technology, data components, trusted data space technology, and data sandbox technology [5]. - Current technologies like blockchain and privacy computing are not yet mature enough for widespread application due to efficiency issues, particularly in sectors like finance where they are currently utilized [5]. Group 4: Future Directions - The future of national data infrastructure is expected to converge into a singular "space," "platform," or "network" where data can flow efficiently and securely [10]. - The construction of this space will involve various technologies, but the essential requirement is the presence of numerous data supply entities, application scenarios, and service providers [10]. Group 5: Addressing Data Inequality - The need to bridge the "data gap" across different industries is emphasized, with a focus on ensuring that all sectors, including manufacturing and agriculture, can leverage data for digital transformation [12]. - The national data infrastructure aims to solve the "data equality" issue, enabling artificial intelligence and other technologies to thrive by providing high-quality data [14].
