摘要:This paper makes two methodological contributions. First, it proposes a framework to decompose total production activities at the country, sector, or country-sector level, to different types, depending on whether they are for pure domestic demand, traditional international trade, simple GVC activities, and complex GVC activities. Second, it proposes a pair of GVC participation indices that improves upon the measures in the existing literature. We apply this decomposition framework to a Global Input-Output Database (WIOD) that cover 44 countries and 56 industries from 2000 to 2014 to uncover evolving compositions of different production activities. We also show that complex GVC activities co-move with global GDP growth more strongly than other types of production activities.

 

We develop a new set of country-sector level indicators of Global Value Chains (GVCs) characteristics in terms of average production length, and relative “up streamness” on a production network, which we argue are better than the existing ones in the literature. We distinguish production activities into four types: those whose value added is both generated and absorbed within the country, those whose value-added crosses borders only once for consumption, those whose value added crosses borders only once for production, and those whose value added crosses borders more than once. Based on such an accounting framework, we further decompose total production length into different segments. Using these measures, we characterize cross-country production sharing patterns and their evolution for 56 sectors and 44 countries over 2000-2014. While the production chain has become longer for the world as a whole, there are interesting variations across countries and sectors.
