摘要：数字政府建设是数字中国战略的重要组成部分，是推进国家治理体系和治理能力现代化的重要举措之一。本文利用政府工作报告进行文本分析并测算城市层面数字政府建设水平，基于2007—2023年沪深A股上市公司数据，实证检验了数字政府建设对企业绿色技术创新的影响及其作用机制。研究结果表明：数字政府建设对辖区内企业绿色技术创新具有促进作用，并且该结论经过一系列稳健性检验后仍然成立。机制分析表明，数字政府建设主要通过降低制度性交易成本、缓解企业信息不对称和强化环境规制实施三个机制促进企业绿色技术创新。异质性分析发现，数字政府建设对企业绿色技术创新的促进效应在大规模企业、重污染企业、位于东部地区的企业以及高知识产权保护地区的企业中更为明显。本文的研究为从政府数字化角度驱动企业绿色技术创新提供了经验证据，为进一步推动数字化绿色化协同转型发展提供了重要启示。

Research on the Impact of Digital Government Construction on Enterprises' Green Technology Innovation

Abstract: In recent years, the number of green patent grants in China has shown a gradual upward trend. However, the majority of green innovation outputs have originated from public research institutions such as universities, whereas enterprises have not assumed a leading role in green technological innovation. Meanwhile, digital technologies such as big data and cloud computing have been booming and integrated into all areas of economic and social development. The synergistic transformation toward digitalization and greening is crucial for strengthening firms' capacity for green technology innovation.

Unlike prior studies that primarily examined digitalization from an internal corporate perspective, this paper extends the analysis of its impact on green development to government institutions at the city level. This paper employs text analysis of government work reports to capture the level of digital government development. Based on data from China's A-share listed firms from 2007 to 2023, this paper empirically examines the impact of digital government construction on enterprise green technology innovation.

The results demonstrate that digital government construction effectively promotes enterprise green technology innovation. To address potential endogeneity concerns, this paper employs an instrumental-variable approach using 2SLS. Additionally, robustness is tested using various methods, including variable substitution and model substitution. Mechanism analysis reveals that digital government construction primarily drives enterprise green technology innovation by reducing institutional transaction costs, alleviating information asymmetry among enterprises, and strengthening environmental regulation enforcement. This paper examines heterogeneity by grouping firms according to size, industry characteristics, and geographic location for regression analysis. The findings reveal that digital government construction exerts a stronger effect on green technology innovation in large-scale enterprises and heavily polluting enterprises. Enterprises located in eastern regions and in regions with stronger intellectual property protection experience a stronger effect of digital government construction on green technology innovation. The result indicates that the impact of digital government construction on green technology innovation varies across enterprises with different characteristics.

This paper puts forward the following policy implications. First, more proactive measures should be undertaken to advance digital government construction, with particular emphasis on improving its quality. Second, digital government construction should be leveraged to optimize the business environment by reducing institutional transaction costs for enterprises and alleviating their burdens, while simultaneously strengthening governmental environmental governance through the establishment of an integrated environmental monitoring platform. Third, differentiated policies should be formulated to provide targeted support according to enterprise scale, industry sector, and geographic location.
