【摘要】 在对增长目标约束和数字基础设施建设(简称“数字基建”)二者关系进行分析的基础上，利用2006—2020年282个地级以上城市的面板数据实证检验增长目标约束如何影响数字基础设施建设，结果发现：(1)增长目标约束将通过政府关注效应和资金支持效应促进数字基建，软约束可以显著促进数字基建，但硬约束则相反。(2)增长目标约束对于数字基建的影响受到市场化水平和人力资本水平的影响。市场化水平越低(人力资本水平越高),增长目标约束对于数字基建的促进作用越强。(3)异质性分析表明，与东部地区相比，增长目标约束对于中西部地区城市的数字基建水平的促进效果更强。同时，增长目标约束对于数字基础设施建设的促进作用仅在2012年后成立，且负向的社会绩效反馈差距比正反馈对数字基建的提升作用更大。以上结论有助于理解政府在数字基建中承担的角色，为更好促进数字基建高质量发展提供了政策启示。更多还原

【Abstract】 Based on the analysis of the relationship between growth target constraint and digital infrastructure construction, the panel data of 282 cities above prefecture level from 2006 to 2020 are used to empirically examine how growth target constraint affects the construction of digital infrastructure.The empirical results show that:(1) Growth target constraint will promote digital infrastructure through government attention effect and financial support effect.Soft constraint can significantly promote digital infrastructure, but hard constraint cannot;(2) The influence of growth target constraint on digital infrastructure is influenced by marketization and human capital. The lower the level of marketization(the higher the level of human capital), the stronger the role of growth target constraint in promoting digital infrastructure;(3) Heterogeneity analysis shows that compared with the eastern region, the growth target constraint has a stronger promotion effect on the digital infrastructure in the central and western regions. At the same time, the promotion effect of growth target constraint on digital infrastructure construction is only existed after 2012, and the negative social performance gap is more important than the positive feedback. The above-mentioned conclusions are helpful to understand the role of the government in digital infrastructure and provide policy enlightenment for better promotion of the high-quality development of digital infrastructure.更多还原
