司法数字化是数字政府建设的重要组成部分,对企业创新环境具有深远影响。本文基于“互联网法院设立”这一准自然实验,以我国2012—2022年A股上市公司为研究对象,采用多期双重差分法(DID)实证检验司法数字化改革对企业创新效率的影响效果及作用机制。研究发现,互联网法院的设立显著提升了企业的创新效率,该效应主要通过强化知识产权保护、优化企业信用环境两条路径加以实现,且在非国企、低竞争行业以及资本密集度低的企业中,这种提升作用更为显著,进一步发现,这种影响随时间推移逐步增强。该研究为司法体系数字化改革赋能企业创新提供了微观证据,也为构建高效协同的数字治理体系提供决策参考。

Judicial digitalization is a crucial component of digital government construction and exerts a profound impact on the corporate innovation environment. Based on the quasi-natural experiment in "establishment of Internet courts", this study employed a multi-period DID approach to empirically examine the effect and mechanism of judicial digitalization reform on corporate innovation efficiency, using a sample of China's A-share listed companies from 2012 to 2022. The findings indicated that the establishment of Internet courts significantly enhances corporate innovation efficiency. This effect is primarily achieved through two mechanistic channels: strengthening intellectual property protection and optimizing the corporate credit environment. Furthermore, it is more pronounced in non-state-owned enterprises, industries with low competition levels, and low capital-intensive enterprises. Additional analysis revealed that the promoting effect gradually strengthens over time. This study will provide micro-level evidence for how judicial digitalization empowers corporate innovation, while offering valuable decision-making insights for constructing an efficient and collaborative digital governance framework.
