Abstract

The role of government-driven investment in improving environmental quality has long been an essential concern of environmental research. Using a spatial difference-in-differences model, this study investigates the influence of government-driven new infrastructure investment on green innovation. Based on a panel dataset of 276 Chinese cities from 2005 to 2019, we find a positive effect of high-speed rail (HSR) and smart city (SC) construction on green innovation. Compared with cities that are unconnected to the HSR network, those that are accessible by HSR experienced a 20.6 % increase in per capita green patents. In addition, being a SC planned by the government is associated with 14.8 % more green patents per capita than other cities. Moreover, government-promoted new infrastructure has significant spatial spillover effects on green innovation in adjacent cities. Regional sensitivity is found in promotional and spatial spillover effects. The findings of our study offer essential insights for developing effective policies for advancing infrastructure modernization and environmental protection simultaneously.

政府推动的基础设施能否促进绿色创新？中国新基础设施计划的证据

长期以来，政府主导的投资在改善环境质量方面的作用一直是环境研究的一个重要关注点。本研究采用空间差分模型，探讨了政府主导的新型基础设施投资对绿色创新的影响。基于 2005 年至 2019 年中国 276 个城市的面板数据集，我们发现高铁（HSR）和智慧城市（SC）建设对绿色创新有积极影响。与未通高铁的城市相比，通高铁的城市人均绿色专利增加了 20.6%。此外，与其他城市相比，由政府规划的高铁沿线城市的人均绿色专利数量增加了 14.8%。此外，政府推动的新基础设施对相邻城市的绿色创新具有显著的空间溢出效应。在促进效应和空间溢出效应中发现了区域敏感性。我们的研究结果为制定同时推进基础设施现代化和环境保护的有效政策提供了重要启示。
