Abstract: Increasing the share of labor income in enterprises is an important way to optimize the income distribution pattern and achieve modernization with Chinese characteristics. Against this backdrop, it is particularly important to conduct an in-depth investigation into the influencing factors of enterprise labor income share. This paper measures the digital-real industrial technology integration with the patent citation information and conducts an empirical study on the basis of the non-financial A-share listed enterprises in Shanghai and Shenzhen stock exchanges from 2008 to 2022 as samples. The findings reveal that digital-real industrial technology integration can significantly enhance enterprise labor income shares. The mechanism analysis indicates that digital-real industrial technology integration promotes the upgrading of enterprise human capital structure, thereby increasing enterprise labor income share. The heterogeneity analysis demonstrates that, in terms of enterprise characteristics, the positive effect of digital-real industrial technology integration on the labor income share is more pronounced in non-state-owned enterprises and high-tech enterprises. From the perspective of external environments, the enhancing effect is more substantial for enterprises located in regions with higher levels of intellectual property protection and more advanced digital infrastructure development. Based on these conclusions, to further leverage the role of digital-real industrial technology integration in boosting enterprise labor income share, it is imperative to improve digital technology infrastructure, optimize the supply-demand structure of the labor market, and advance digital-real industrial technology integration through tailored policies adapted to the enterprise-specific and region-specific conditions.
