沉没成本的跨期效应和企业异质性对出口行为的影响The Impact of Inter-temporal Effect of Sunk Cost and Firm Heterogeneity on Export
智冬晓,许晓娟
摘要(Abstract):
从出口发生概率的角度分析沉没成本的跨期效应及企业异质性对出口行为的影响,克服了使用传统出口决策模型所面临的线性相关、分布假定失真及检验失效等问题。结果表明,按照统计时点分割出口状态并没有充分描述企业的出口行为,沉没成本的跨期效应明显高于即期效应;内外资企业出口倾向有显著差异,但差异不大;全要素生产率和工资水平会促使企业有更高的出口倾向,但企业特质因素的交互效应使出口变得复杂,高生产率高工资水平不一定会提高企业的出口倾向,说明"生产率悖论"客观存在。整体上看,沉没成本和企业异质性是影响企业出口的重要因素,但并非决定性因素。
