【摘要】 基于2004—2022年中国30个省级（剔除港澳台和西藏地区）面板数据，运用固定效应和中介效应模型考察新型基础设施建设对先进制造业与现代服务业融合发展的影响及传导机制。研究发现：新型基础设施建设对两业融合发展具有显著的赋能效应。该结论在一系列内生性及稳健性检验后依然成立；机制检验发现，新型基础设施建设通过提升人力资本和技术创新水平赋能两业融合发展；区域异质性分析表明，新型基础设施建设对中西部地区两业融合的赋能效应大于东部地区；不同类别新型基础设施建设对两业融合发展的赋能效应不同，其中，融合基础设施建设和创新基础设施建设赋能效应更为显著。因此，新型基础设施建设需加大投资力度、打通作用渠道、实施差异化投资政策，以进一步推动两业深度融合发展。更多还原

【Abstract】 Drawing on panel data from 30 Chinese provincial-level regions(excluding Hong Kong, Macao, Taiwan, and Tibet) from 2004 to 2022, this study employs fixed-effect and mediation effect models to examine the impact of new infrastructure construction on the integrated development between advanced manufacturing and modern service industries, as well as its transmission mechanisms.The study reveals that new infrastructure construction significantly empowers the integrated development between the two industries, which is also a true conclusion after a series of endogeneity and robustness tests. Mechanism analysis indicates that new infrastructure construction facilitates the integration by enhancing human capital and technological innovation. Regional heterogeneity tests show that the enabling effect is stronger in central and western regions than in eastern regions. Moreover, different categories of new infrastructure construction exhibit varying effects, with integrated infrastructure and innovation infrastructure demonstrating the most pronounced enabling effects.Therefore, it is necessary to increase investment in new infrastructure, to unblock its functional channels, and to implement differentiated investment policies to further promote the in-depth integrated development between the two industries.更多还原
