技术溢出及政策歧视对R&D补贴效果的影响

The effect of technology spillover and discrimination of subsidy policy on the effect of R D subsidy

摘要:

R&D补贴作为政府激励企业进行自主创新的一项财政投入,学者对其激励效应有互补、替代及不显著相关的观点。本文建立一个博弈模型,力图揭示R&D补贴对企业创新活动决策的影响机制。研究发现补贴政策的实施效果受技术溢出水平、政策的歧视性及行业特征的多重影响,并非呈现单一的互补或替代性。最后,文章给出不同情况下提高政策实施针对性和准确性的方法和建议。
