Outline
In the context of the in-depth implementation of the "Dual Carbon" strategy goal, the synergistic development of digital transformation and green innovation has become a key pathway for the sustainable development of mining enterprises. Based on a sample of A-share listed companies in China's mining industry from 2015 to 2024, the impact and underlying mechanisms of digital transformation on the green innovation efficiency of mining enterprises were systematically investigated. Furthermore, the existence of a peer effect in digital transformation and its exogenous impact on green innovation efficiency were verified at the regional level. The results demonstrate that digital transformation significantly improves the green innovation efficiency of mining enterprises, a conclusion that remains valid after endogeneity treatments and robustness tests. Regarding the functional mechanisms, digital transformation promotes green innovation efficiency by optimizing resource allocation efficiency, enhancing information transparency, and reducing supply chain concentration. This promoting effect is particularly pronounced among upstream supply chain enterprises, state-owned enterprises, and heavily polluting enterprises. Moreover, the digital transformation of mining enterprises exhibits a distinct regional peer effect, which in turn significantly facilitates the enhancement of their green innovation efficiency.
