Internet Plus New Infrastructure is a key component of the Internet Plus initiative. This study analyzes the demand,development status, and problems regarding the Internet Plus New Infrastructure mode, and proposes that establishing the Internet Plus New Infrastructure mode requires addressing the effective aggregation, integration, and application of massive data and ensuring realtime processing and response with high concurrency, low latency, and high security and reliability of network services. This study also demonstrates the typical construction path for constructing the Internet Plus New Infrastructure mode, that is, to address the efficient integration and effective use of city data through the construction of data middle offices and to provide both high-throughput and high quality services through the “information high-speed rail stations.” The concepts and technical essentials of the data middle offices and information high-speed rail stations are analyzed, which are the core infrastructures of the Internet Plus initiative. To promote the Internet Plus initiative in China, countermeasures and suggestions for the construction of the Internet Plus New Infrastructure mode in cities are proposed from the perspective of planning, policy implementation, and flexible operating models.
