Do Global Value Chains Enhance Economic Upgrading? A Long View
研究了1970-2008年间全球价值链参与对多国生产率增长和就业的长期影响，发现对制造业生产率有正面作用，但对就业无显著影响。
Exporting through global value chains (GVCs) has recently been highlighted as a panacea for weak industrialisation trends in the South. We study the long-run effects of GVC participation for a large set of countries between 1970 and 2008. We find strong evidence for the positive effects on productivity growth in the formal manufacturing sector. This effect is stronger when the gap with the global productivity frontier is larger. However, we find no evidence for a positive effect on employment generation. These findings also hold in analyses of sub-sets of countries and industries and are robust to the inclusion of non-manufacturing employment.
