Global value chain (GVC) research has evolved from a theoretical framework to become an applied research approach over the last 20 years. As described in detail in other chapters of the Handbook and elsewhere, the GVC framework was developed based on case studies and qualitative firm-based research. As GVC analysis has increasingly gained the atten- tion of policymakers, there has become a need to link theoretical concepts to a definable research approach. This shift from theory to application has also led to the use of more standardized data sources to enable comparability and repeatability over time. Applied research implies that actionable recommendations can be made based on the outcomes of using the framework. The objective is no longer just to explain how and why certain countries participate in an industry, but also to determine how successful a country has been in the industry and to provide recommendations on how this can be sustained or increased into the future. In today’s data-driven world, to be useful for policymakers and government agencies, these comparisons and recommendations need to have at least esti- mated quantifiable metrics on key topics such as increases in exports, output, employment, wages or skill levels. This requires the use of industry-specific national and firm-level data.
