构建城市“互联网 +”新型基础设施是我国深入推进“互联网 +”行动计划发展的关键领域。本文在分析需求、发展现状及面临问题的基础上，提出构建城市“互联网 +”新型基础设施需应对海量数据的有效汇聚、融合和应用，确保网络服务高并发、低延迟、高安全可靠的实时处理和响应。研究论证了构建城市“互联网 +”新型基础设施的典型建设路径，即通过建设数据中台解决城市数据的高效融合和有效利用问题，通过城市“信息高铁站”提供高通量和高品质的服务，剖析了二者作为城市“互联网 +”新阶段核心基础设施的概念支撑与技术要点。为推进我国“互联网 +”的纵深发展，本文从前瞻规划、因城施策以及建设灵活运营模式等方面给出了建设城市“互联网 +”新型基础设施的对策建议。

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.
