Empowering Enterprises New Quality Productive Forces Through Digital Supply Chains: Mechanisms and Policy Implications

As a core component of digital transformation, the digital supply chain serves as a critical driving force behind the qualitative leap in enterprise productivity. Based on panel data from Chinas A-share main board listed companies in Shanghai and Shenzhen from 2015 to 2022, this study builds on existing research to conduct an in-depth analysis of the impact and mechanisms through which digital supply chains influence enterprises new quality productive forces. The results reveal that: (1) Digital supply chains significantly and positively enhance enterprises new quality productive forces, a finding that holds robust across various tests; (2) Digital supply chains foster the development of new quality productive forces by reducing supplier concentration; (3) The power structure of corporate management plays an important moderating role, with board size exerting negative moderating effect, while equity dispersion has a positive moderating effect; (4) These effects exhibit notable heterogeneity across ownership types, firm sizes, and regions. The findings of this study not only enrich the theoretical understanding of digital supply chains and new quality productive forces, but also offer practical pathways for policymakers and enterprise managers in China to seize the opportunities of digital transformation.
