贸易政策不确定能否倒逼出口企业创新

利用2000—2013年中国出口企业微观数据，实证研究贸易政策不确定对出口企业创新的影响。结果表明，贸易政策不确定显著倒逼我国出口企业创新。不同维度的异质性分析发现，贸易政策不确定对我国高市场化程度地区、非国有及劳动资源密集型出口企业的创新激励作用更为强烈。进一步从劳动力成本、融资约束及政府补贴效应三个渠道揭示贸易政策不确定对出口企业创新的作用机制，发现劳动力成本和政府补贴强化了贸易政策不确定对出口企业的创新作用，而融资约束阻碍了这种影响。

A Study on Whether Trade Policy Uncertainty Motivates Exporters to Innovate

The results show that the trade policy uncertainty significantly stimulates Chinese export enterprises to innovate. The heterogeneity analysis of different dimensions shows that the trade policy uncertainty has a stronger incentive effect on innovation of the area with high degree of marketization, non-state-owned and labor-resource-intensive export enterprises. Further, from labor costs, financing constraints and government subsidy effect to reveal how trade policy uncertainty motivates export enterprise innovation. The results find that labor costs and government subsidies strengthen the innovative effect of trade policy uncertainty on export enterprises, and financing constraints hinder this effect.
