摘要：    在关税竞争背景下，国际客户关系稳定面临挑战，由此引发的客户关系重构会影响到企业创新动力和能力。本文基于手工收集的国内外客户关系重构数据，以中美贸易摩擦为准自然实验，选取2015—2021年中国沪深A股上市公司为研究样本，运用双重差分模型考察关税竞争下国内外客户关系重构对企业创新投入的影响及作用机制。研究发现：（1）关税竞争引致的国内外客户关系重构促进了企业创新投入，该促进效应主要通过信息透明度和政府补助实现；（2）基于企业层面的异质性分析发现，在海外业务收入低、国有企业和议价能力高的企业中，关税竞争引起的国内外客户关系重构对创新投入的促进作用更明显；基于地区、行业层面的异质性分析表明，这种促进作用在市场化进程快、政府产权保护水平高和非高技术行业中更显著；（3）经济后果研究发现，关税竞争引起的客户关系重构导致创新绩效不升反降。本文研究为理解创新活动提供了来自国际大环境和供应链关系方面的解释，也为企业的供应链管理提供了参考。

Abstract:    Under the background of tariff competition, the stability of international customer relationship is facing great challenges, and the reconstruction of customer relationship will affect the innovation power and ability of enterprises. Based on the data of customer relationship reconstruction at home and abroad collected by hand, and taking the Sino-US trade friction as the quasi-natural experiment, this paper selected the A-share listed companies in China from 2015 to 2021 as the research sample, and used the difference-in-differences model to investigate the influence and action mechanism of customer relationship reconstruction at home and abroad on enterprise innovation investment under tariff competition. The findings are as follows: (1) the reconstruction of customer relationship at home and abroad caused by tariff competition promotes the innovation investment of enterprises, which is mainly achieved through information transparency and government subsidies; (2) Based on the heterogeneity analysis at the enterprise level, it was found that among enterprises with low overseas business income, state-owned enterprises and high bargaining power, the reconstruction of domestic and foreign customer relations caused by tariff competition has a more obvious role in promoting innovation investment; moreover, the heterogeneity analysis based on regional and industry level showed that this promotion is more significant in high marketization process, high level of government property protection and non-high-tech industries; (3) The study of economic consequences showed that the reconstruction of customer relationship caused by tariff competition leads to the decline of innovation performance instead of rising. The research will provide an explanation from the international environment and supply chain relationship for understanding innovation activities, and also provide reference for supply chain management of enterprises.
