Research on the Impact of Digital Transformation Network Peer Groups on Corporate Carbon Neutrality Performance: Based on the Interlocking Directorate Network

From the perspective of the interlocking directorate network, investigating the impact of digital transformation network peer groups on corporate carbon neutrality performance holds substantial significance for enterprises in accomplishing green and low-carbon transformation within the digital economy framework. Using Shanghai and Shenzhen A-share listed companies from 2018 to 2023 as research samples, this study empirically explores the existence of a digital transformation peer effect within the interlocking directorate network and its influence on corporate carbon neutrality performance, as well as the moderating effect of the supply chain concentration. The results indicate the following: (1) A digital transformation peer effect exists within the interlocking directorate network and significantly improves the carbon neutrality performance of enterprises. (2) The aforementioned positive effect is more pronounced under lower supply chain concentrations. (3) The green innovation level of enterprises serves as an intermediary factor between the digital transformation network peer group and the carbon neutrality performance of enterprises. (4) In regions characterized by stringent environmental regulations, capital-intensive industries, and large-scale enterprises, the digital transformation network peer group exerts a more significant impact on the enhancement of carbon neutrality performance. These results offer a reference for facilitating the formation of digital transformation network peer groups, improving corporate carbon neutrality performance, and consequently attaining sustainable development.
