摘要：

本文构建一个异质性企业家模型,以中国现实数据为基础,利用数值模拟深入考察公共基础设施投资对全要素生产率(TFP)的影响机理,同时考虑金融摩擦、劳动摩擦和其他财税政策对公共基础设施投资TFP效应的抑制作用。研究表明,公共基础设施投资对TFP具有明显的"倒U型"影响,即存在TFP最大化的公共基础设施投资规模。这源于公共基础设施投资影响企业家的财富积累,即自融资机制,对企业间要素配置的重要影响。信贷约束对公共基础设施投资的TFP效应影响显著(企业家面临的信贷约束越严重,公共基础设施投资对TFP的影响越大)。存贷利差的影响则较弱。减少劳动摩擦可增强公共基础设施投资的TFP效应,较大的有效基础设施服务、企业间差异性和公共消费性支出也具有类似影响,利用消费税融资可更好地发挥公共基础设施投资对TFP的促进作用。
