发展中国家的全球价值链：基于咖啡与服装的关系性视角

There is a consensus that global value chains have aided developing countries' growth. This essay highlights the governance complexities arising from participating in such chains, drawing from lessons we have learned conducting research in the coffee and garment supply chains. Market power of international buyers can lead to inefficiently low wages, prices, quality standards, and poor working conditions. At the same time, some degree of market power might be needed to sustain long-term supply relationships that are beneficial in a world with incomplete contracts. We discuss how buyers’ market power and long-term supply relationships interact and how these relationships at the export-gate could be leveraged to enhance sustainability in the domestic part of the chains. We hope that the lessons learned by combining detailed data and contextual knowledge in two specific chains—coffee and garments—have broader applicability to other global value chains.
