Drivers of productivity change in global value chains: Reallocation vs. innovation
研究了技术进步与市场份额重新配置如何影响全球部门劳动生产率变化，发现国家间的重新配置比国内创新对生产率变化的影响更大。
We investigate the role of technological improvement and market share reallocation in determining global changes in sectoral labor productivity. Contrary to previous work that neglects dependencies between suppliers in global value chains, we account for input linkages that impact both channels of productivity improvement. Using sector-level data from the World Input–Output Database, we show that reallocation between countries has a larger effect on productivity change than innovation within countries.
