Abstract

Suppliers are important stakeholders of enterprises, which affect the enterprise resource allocation. Utilizing data from A-share listed companies in China between 2007 and 2022, our findings indicate that supplier concentration significantly reduces the labor income share by inhibiting the innovation demand of enterprises digital transformation and green innovation. Furthermore, we find that supplier concentration has a significantly stronger inhibition effect on the labor income share of enterprises of non-state-owned, low-level market competition and high-level marketization degree. These findings not only provide new insights into the research on the labor income share but also guide enterprises to optimize their supplier structures.
