New quality productive forces,supply chain in-depth digitalization,and corporate carbon performance:evidence from key digital technology patents
This study focuses on the new quality productive forces driven by key digital technologies.Based on data from China's list-ed companies and small and medium-sized enterprises (SMEs) in the supply chain from 2008 to 2022,it empirically examined their im-pact on corporate carbon performance using methods such as a quasi-natural experiment with the 5G pilot policy.The study conducted a multi-faceted mechanism analysis from the new perspective of supply chain in-depth digitalization.The empirical results revealed that:① Unlike general digital technology innovation,the new quality productive forces led by key digital technologies had a stronger ef-fect on improving corporate carbon performance,as confirmed by a series of robustness tests including staggered difference-in-differenc-es (DID),instrumental variables,and machine learning models.However,there was no significant overall carbon reduction effect,and the impact on the carbon performance of the entire supply chain remained limited.② For the first time,the mechanisms of supply chain in-depth digitalization were explored.The results showed that the new quality productive forces led by key digital technologies had a more substantial effect on supply chain digitalization,improving energy efficiency in production and enhancing supply chain efficiency,demand-supply matching,supply relationship stability,and supplier innovation.③ The study also explored the mechanisms of digital supply chain finance,finding that unlike the insignificant effect of general digital technology innovation,digital supply chain finance significantly improved information asymmetry and alleviated financing constraints in the supply chain.Based on these findings,the study recommends that efforts should focus on strengthening the R&D and application of key digital technologies,promoting the in-depth digitalization of supply chains,and developing digital supply chain finance to explore 'de-nuclearization' models,ultimately con-tributing to the achievement of the 'dual carbon' goals.
