摘　　要：文中以2018-2022年A股制造业企业为研究样本,旨在深入探讨供应商集中程度对企业研发投入力度的影响机制,并特别聚焦于商业信贷在此过程中的潜在中介作用。进一步地,文中还分析了政府补助作为调节变量,如何影响供应商集中度与企业研发投入之间的关联。结果表明:供应商集中度与企业研发投入之间呈现显著的负向关系,同时商业信贷在其中起着中介作用。政府补助能够显著削弱供应商集中度对企业研发投入的负向影响,并且也能够削弱商业信贷对企业研发投入的正向影响。文中从供应链视角提供了影响企业研发投入的因素,并且提供了政府补助能够缓解供应商集中度对企业研发投入的影响的经验证据。Taking A-share manufacturing enterprises from 2018 to 2022 as research samples,this paper aims to deeply explore the mechanism of the influence of supplier concentration on the intensity of R&D investment of enterprises,and especially focus on the potential intermediary role of commercial credit in this process.Further,this paper also analyzes how government subsidies,as a moderating variable,affect the relationship between supplier concentration and R&D investment.The results show that there is a significant negative relationship between supplier concentration and R&D investment,and commercial credit plays an intermediary role.Government subsidies can significantly weaken the negative impact of supplier concentration on R&D input,and can also weaken the positive impact of commercial credit on R&D input.From the perspective of supply chain,this paper provides the factors that affect enterprises R&D input,and provides the empirical evidence that government subsidies can mitigate the influence of supplier concentration on enterprises R&D input.
