摘要：公共服务信息化是数字化技术与公共服务的有机结合，其能否促进城市绿色技术创新有待检验。文章使用2007—2019年城市面板数据，基于信息惠民国家试点政策构建双重差分模型探究公共服务信息化对区域绿色创新的影响效应和作用机制。实证结果表明：公共服务信息化对区域绿色创新有显著的促进作用，且通过了稳健性检验。在中西部、人口规模大和行政等级低的城市，公共服务信息化对区域绿色创新的影响更加显著。正式和非正式型环境监管均在公共服务信息化对区域绿色创新的影响中起到正向调节的作用。公共服务信息化通过人才集聚和经济集聚对区域绿色创新起到显著的促进作用。因此，建议全方位推进数字化治理，加强治理数字化的力度；重点支持中西部规模大城市，加快中西部地区数字化治理转型；支持、引导人才集聚和经济集聚，形成创新生态系统；建立健全环境监管体系，加强环境监管力度。

Public Service Informatization and Regional Green Innovation: Analysis of the Regulatory Role Based on Formal and Informal Environmental Regulation
Hao Yu, Li Zhichao
Abstract: Public service informatization represents the integration of digital technology with public services, and its potential to foster urban green technological innovation remains to be fully examined. This study utilizes panel data from cities spanning 2007 to 2019 and employs a difference-in-differences model based on the National Pilot of Information for the People policy to investigate the impact and mechanisms of public service informatization on regional green innovation. The empirical results indicate that public service informatization significantly promotes regional green innovation, and this finding is robust across various tests. The positive impact is particularly pronounced in cities located in central and western regions, those with larger populations, and those with lower administrative levels. Both formal and informal environmental regulations positively moderate the effect of public service informatization on regional green innovation. The mechanisms through which public service informatization promotes green innovation include talent concentration and economic agglomeration. Consequently, it is recommended to comprehensively promote digital governance and enhance the digitization of governance processes. Government should focus on supporting large cities in central and western regions and expedite the transformation of digital governance in these areas; support and guide talent and economic agglomeration to create an innovation ecosystem; establish a robust environmental regulatory system and strengthen environmental regulations.
