There are several ways to define and measure the Digital Economy, making it difficult to set effective policies.
A 2020 OECD report for the for the G20 Digital Economy Task Force, Roadmap toward a Common Framework for Measuring the Digital Economy, proposes a common definition and a tiered framework to help establish clear, comparable measures for policy making:
"The Digital Economy incorporates all economic activity reliant on, or significantly enhanced by the use of digital inputs, including digital technologies, digital infrastructure, digital services and data. It refers to all producers and consumers, including government, that are utilising these digital inputs in their economic activities."
This overarching proposed policy definition is combined with a tiered definitional framework to not only assist with accurate measurement and comparability of the digital economy by statistical offices but to also allow for the incorporation of digitalised interactions not currently recorded as economic activity.
