摘要：This paper aims to overview the recent body of empirical work on the importance of Global Value Chains (GVCs) in international production and trade. We begin by reviewing different approaches and levels of GVC analysis. We then consider developments in methods and data. Focusing on the agriculture and food sector, we present a map of GVC measures - at the country and sectoral level - computed using trade in value added data to allow researchers to better assess the countries’ engagement in GVCs. We also apply this data to show some stylized facts on GVC participation and positioning in agriculture and food and provide empirical evidence of the economic impact of the GVCs on these sectors. We conclude with some critical issues and speculative thoughts regarding the future of GVCs.
