摘要
R&D投资是企业技术创新的源泉,但是,其资金来源受到企业内部资金水平和外部融资条件的制约。本文以2002~2010年我国制造业上市公司为样本,实证研究了融资约束对企业R&D投资的影响,并考察了企业的现金持有行为对R&D投资的平滑效应。研究结果表明,融资约束企业的R&D投资系统地依赖于内部现金流,而非融资约束企业的R&D投资更多地依靠债务融资,对内部现金流的依赖性不明显。进一步研究发现,融资约束企业持有现金对R&D投资具有平滑效应,并降低了R&D投资与内部现金流的敏感性,但这种现金平滑效应在非融资约束企业中表现得不明显。研究结论拓展了关于融资约束与企业投资行为的研究,并加深了对企业持有现金进行流动性管理的理解。
