本文利用2000-2013年中国工业企业数据库和高度细化的中国海关数据库匹配后的数据为样本,研究美国货币政策不确定性对中国出口企业创新的溢出效应和作用机制。结果显示,美国货币政策不确定性对中国出口企业创新存在促进作用,平均来看美国货币政策不确定性上升1%,出口企业研发支出增加0.051%,新产品产值增加0.187%,并且企业出口强度越大,这种促进作用越强。美国货币政策不确定性对竞争程度高的企业组的创新促进作用更强,表明美国货币政策不确定性通过竞争机制促进中国出口企业创新。异质性性检验表明,融资约束越低,企
This paper uses the data obtained after matching the Chinese industrial enterprise database and the highly detailed Chinese customs database from 2000 to 2013 as a sample to study the spillover effect and mechanism of the US monetary policy uncertainty on the innovation of Chinese export enterprises. The results show that the uncertainty of U.S. monetary policy promotes the innovation of Chinese export companies. The uncertainty of U.S. monetary policy has increased by 1% on average, the R&D expenditure of export companies has increased by 0.051%, and the output value of new products has increased by 0.187%. The greater the export intensity, the stronger this promotion. The uncertainty of U.S. monetary policy has a stronger effect on the innovation of highly competitive business groups, indicating that the uncertainty of U.S. monetary policy can promote the innovation of Chinese export companies through the competition mechanism. The heterogeneity test shows that the lower the financing constraints, the more subsidies companies receive, and the stronger the promotion of the uncertainty of U.S. monetary policy. The innovation of private enterprises is significantly greater than that of state-owned enterprises and foreign-funded enterprises.
