新型基础设施是我国经济社会高质量发展的重要支撑依据。同时,新型基础设施建设区别于传统基础设施建设,其具有更广阔的内需空间,是扩大内需的重要发展潜力点。基于此,本文采用因子分析法对我国新型基础设施建设的高质量发展进行水平测度分析,并在此基础上实证分析2018~2022年30个地区新型基础设施建设对我国扩大内需发展的影响及区域差异效应分析。研究结果表明:1) 我国新型基础设施建设发展水平在稳步提升,融合、技术、城镇环境方面建设贡献率最大,具有显著的促进作用。2) 区域新型基础设施建设发展存在区域性不均衡情况。东部经济发达地区总体发展较好,中西部地区发展空间较大。3) 实证分析表明,新型基础设施建设对扩大内需水平具有显著的正向促进作用,东部地区的新型基础设施水平对内需的促进作用最为有效。The new infrastructure is an important support for the high-quality development of China’s economy and society. At the same time, the new infrastructure construction is different from the traditional infrastructure construction, which has a broader space for domestic demand and is an important development potential point for expanding domestic demand. Based on this, this paper uses factor analysis to measure and analyze the high-quality development of new infrastructure construction in China, and on this basis, empirically analyzes the influence of new infrastructure construction in 30 regions on expanding domestic demand in China from 2018 to 2022 and the regional difference effect analysis. The research results show that: 1) The development level of new infrastructure construction in China is steadily improving, and the construction of integration, technology and urban environment has the greatest contribution rate, which has a significant promotion effect. 2) There is a regional imbalance in the construction and development of regional new infrastructure
