制度型开放对生产性服务业数字化转型的影响研究——来自中国上市公司的经验证据

Research on the Impact of Institutional Opening-Up on the Digital Transformation of Producer Services—Empirical Evidence from Chinese Listed Companies

摘要: 制度型开放是我国推进高质量发展与国际经济合作的重大举措，为产业数字化转型提供了重要契机。基于2008~2022年中国沪深A股上市公司数据，构建双重差分模型，以丝绸之路经济带建设为准自然实验实证考察了制度型开放对生产性服务业数字化转型的影响效应。研究发现，制度型开放能显著促进生产性服务业数字化转型。异质性结果表明，制度型开放对非国有企业、中低端生产性服务业企业具有显著促进作用。机制检验表明，制度型开放能通过研发投入促进效应、逆向知识溢出效应和数字生态构建效应等渠道促进生产性服务业数字化转型。研究结论为完善推进高质量制度型开放，推动我国生产性服务业数字化水平提升提供了经验证据。

Abstract: Institutional opening-up is a significant measure for China to promote high-quality development and international economic cooperation, providing an important opportunity for the digital transformation of industries. Based on data from Chinese listed companies on the Shanghai and Shenzhen A-share markets from 2008 to 2022, a difference-in-differences model is constructed to empirically examine the impact of institutional opening-up on the digital transformation of productive service industries, using the construction of the Silk Road Economic Belt as a quasi-natural experiment. The study finds that institutional opening-up can significantly promote the digital transformation of productive service industries. Heterogeneity results indicate that institutional opening-up has a significant promoting effect on non-state-owned enterprises and mid-to-low-end productive service industry enterprises. Mechanism tests show that institutional opening-up can promote the digital transformation of productive service industries through channels such as the promotion effect of R&D investment, reverse knowledge spillover effect, and digital ecosystem construction effect. The research conclusion provides empirical evidence for improving and promoting high-quality institutional opening-up and enhancing the digitalization level of China’s productive service industries.
