摘要 从新型城镇化和乡村全面振兴协调发展的视角出发,构建地级市层面的城乡融合发展评价指标体系,厘清了网络基础设施建设影响城乡融合发展的内在机理,并采用双重机器学习方法检验其影响效应及作用路径。研究发现:网络基础设施建设能显著推动城乡融合发展,这一结论在更换机器学习算法、改变自变量和因变量衡量方法、剔除极端值等一系列稳健性检验后依然成立;异质性分析显示,在老龄化程度较低和三产占比较高的区域,网络基础设施建设对城乡融合发展的促进效应更加显著;作用机制分析表明,网络基础设施建设通过提升创新创业能力和促进数字普惠金融发展等途径推动城乡融合发展;进一步分析发现,以数智化和生态化为特征的新型工业化可以显著强化网络基础设施对城乡融合发展的促进效应。研究可为发展新基建、提升城乡融合发展水平,进而推动全体人民共同富裕的中国式现代化提供有益启示。

Abstract: From the perspective of interactive coordination between new-type urbanization and rural vitalization, this study establishes an evaluation index system for urban-rural integrated development at the prefecture-level city scale, clarifies the internal mechanism through which network infrastructure construction affects such development, and employs a double machine learning approach to examine its impact effects and pathways. The study shows that network infrastructure construction can significantly promote urban-rural integrated development. This conclusion remains robust after a series of robustness checks, including replacing machine learning algorithms, altering the measurement methods for independent and dependent variables and excluding outliers. Heterogeneity analysis reveals that the promotive effect of network infrastructure construction on urban-rural integrated development is more pronounced in regions with a lower degree of aging and a higher proportion of tertiary industry. Mechanism analysis indicates that network infrastructure construction advances urban-rural integrated development by enhancing innovation and entrepreneurship capabilities and fostering the development of digital inclusive finance. Further analysis shows that new industrialization characterized by digitalization, ntellectualization and ecologicalization can significantly strengthen the promoting effect of network infrastructure on urban-rural integrated development. The research findings provide useful insights for developing new infrastructure, enhancing the level of urban-rural integrated development, and thereby advancing Chinese modernization to achieve common prosperity for all.
