20 Years of Multi-Level Governance: Where Does It Come From? What Is It? Where Is It Going?

In two decades since the Maastricht Treaty, multi-level governance (MLG) has developed as a conceptual framework for profiling the arrangement' of policy-making activity performed within and across politico-administrative institutions located at different territorial levels. This contribution examines the ways in which the MLG literature has been employed, effectively taking stock of applied research to date. It identifies five main uses of MLG and the different focus of emerging research over time. Considering the most recent scholarship, the contribution explores possible new directions for research, in light of global governance, culminating in a bird's eye view' of MLG over 20 years.
