On World Standards Day, the National Standards Committee unveiled a series of key national standards, including GB/T 34678-2017 *"Smart City Technology Reference Model"*, GB/T 34680.1-2017 *"Smart City Evaluation Model and Basic Evaluation Index System Part 1: Requirements for the Establishment of the Overall Framework and Sub-item Evaluation Indicators"*, GB/T 34680.3-2017 *"Smart City Evaluation Model and Basic Evaluation Index System Part 3: Information Resources"*, and GB/T 34679-2017 *"General Technical Specifications for Smart Mine Information Systems."* These four standards were officially released and represent a major step forward in China’s smart city and mine development initiatives.
Developed and managed by the National Information Technology Standardization Technical Committee (SAC/TC28), with the China Electronics Technology Standardization Institute leading the effort, these standards mark the second batch of smart city-related national standards following the release of GB/T 33356-2016 *"New Smart City Evaluation Indicators."* The new standards aim to provide a structured framework for the implementation and evaluation of smart city projects across various sectors.
The GB/T 34678-2017 standard outlines a reference model for smart cities, covering business frameworks, knowledge management models, and technical models supported by information and communication technology (ICT). It provides guidelines for the overall planning and implementation of smart city ICT infrastructure and specific projects.
GB/T 34679-2017 focuses on the general technical specifications for smart mine information systems. It defines system architecture, network infrastructure, data warehouses, geographic information systems, sensing technologies, automation, and software platforms such as ERP, big data analysis, and emergency command systems. This standard is designed to guide the development of intelligent information systems in mining enterprises.
GB/T 34680.1-2017 establishes the overall framework and sub-item evaluation indicators for smart city assessments. It outlines the principles, requirements, and descriptions for primary and secondary indicators, serving as a foundation for both city-wide and sector-specific smart city planning and evaluation.
GB/T 34680.3-2017 addresses the evaluation of smart city information resources, providing a clear set of metrics to assess the quality and efficiency of information management within urban environments.
In advancing smart city standardization, China has focused on top-level design and systematic layout, establishing a national smart city standardization group and building a comprehensive smart city standard system. By prioritizing immediate needs, the country has successfully developed several national smart city standards.
Dai Hong, Director of the Industry Standards Department at the National Standardization Administration Committee, emphasized that the core of building a new smart city lies in leveraging data integration and sharing to achieve “three integrations and five crosses.†This approach fosters deep integration of services and operations. Basic standards like indicator systems and classification frameworks encourage industries and local governments to refine and incorporate best practices into official norms. Additionally, efforts are ongoing to promote international smart city standardization, driving innovation and enhancing China's global influence in this critical area.
