GVC stands for global value chain. GVCs are analyzed to understand how global industries are organized, trace shifting patterns of global production, and focus on value added from conception to production. There are four key dimensions of GVCs: 1) input-output structure; 2) geographical coverage; 3) form of governance; and 4) institutional framework. Governance refers to the authority and power relationships that determine how resources flow within a chain, and there are five governance typologies ranging from market to hierarchy. Understanding GVCs is important because international trade, global GDP and employment are significantly influenced by them.
