摘　　要：关税作为一种国际贸易保护措施,其中一个目标在于保护国内企业,使其健康发展。现有文献大都探讨关税对全球价值链参与度的直接影响,而忽略了关税所带来的间接影响。为了弥补现有文献的这一不足,本研究利用中介效应模型实证研究了中间产品关税、最终产品关税对中国产业全球价值链参与度的直接影响和间接影响进行了实证考察。实证研究表明,中间产品关税税率不仅可以直接对行业全球价值链参与度产生显著的负向影响,还可以通过降低全要素生产率对行业全球价值链参与度产生显著的负向影响;最终产品关税税率不仅可以直接对行业全球价值链参与度产生显著的负向影响,还可以通过降低研发投入对行业全球价值链参与度产生显著负向影响;这意味着中间产品关税和最终产品关税的直接效用和间接效用都是显著存在的。As an international trade protection measure,one of the goals is to protect domestic enterprises and make them healthy.Most of the existing literature discusses the direct impact of tariffs on the participation of global value chains,while ignoring the indirect effects of tariffs.In order to make up for this deficiency of the existing literature, this paper empirically investigates the direct and indirect effects of intermediate product tariffs and final product tariffs on the participation of China's industrial global value chains.Empirical studies have shown that the intermediate product tariffrate not only has a significant negative impact on the industry's participation in the global value chain,but also can have a significant negative impact on the participation of the industry's global value chain by reducing total factor productivity;the final product tariff rate Not only can it directly have a significant negative impact on the participation of the industry's global value chain,but it can also have a significant negative impact on the participation of the industry's global value chain by reducing R&D investment;this means the direct utility of intermediate product tariffs and final product tariffs.Indirect utility is significant.
