摘要
本文构建了一个基于风险厌恶型多产品企业的贸易模型,以揭示贸易政策不确定性对多产品企业出口产品范围调整的影响,并分析其作用机制。实证结果表明:贸易政策不确定性下降促进了我国企业的专业化生产,主要体现为出口企业的产品种类减少、核心产品的出口份额增加和企业出口产品多元化程度降低;贸易政策不确定性下降对融资约束较低、生产率较高的企业的出口产品范围的影响更大;贸易政策不确定性主要通过分散风险和改变企业面临的竞争压力来影响企业的产品范围。本文的研究结论对于应对国际贸易环境不确定性及我国外贸政策的调整具有启示意义。
This paper builds a trade model based on risk-aversion multi-product firms to investigate the impact of trade policy uncertainty(TPU)on the export product scope of multi-product firms and its mechanisms.Empirical results show that a reduction in TPU significantly promotes firms’specialized production,which is mainly reflected in the decrease in export product varieties,the increase in the export share of their core products and the decline in export product diversification.A reduction in TPU has a greater impact on the export product scope of firms with lower financing constraints and higher productivity.TPU affects the export product scope of firms mainly through diversifying risks and changing competition for firms.Our conclusion has enlightening implications for dealing with the uncertainty of international trade environment and adjusting China’s foreign trade policies.
