How much do global value chains boost innovation?
利用25个国家的行业专利数据，研究发现参与全球价值链平均使国内创新提升5%，且知识溢出效果取决于接收国的吸收能力及前后向联系。
Abstract This paper investigates whether participation in global value chains (GVCs) fosters innovation. Using industry‐level patent data for 25 countries, we estimate how the pool of foreign R&D expenditure available through global value chains affects the production of ideas at home. We find that GVCs boost innovation on average by 5% both in developed and emerging economies. We further show that international knowledge spillovers require good absorptive capacity in the knowledge‐receiving country and that their strength depends on both forward and backward GVC linkages.
