Overcoming left-behindedness. Moving beyond the efficiency versus equity debate in territorial development

Territorial development theory and practice have witnessed significant change in recent times. This change has increasingly put the spatial dimension at the centre of development policies. Where agglomeration-focused policies derived from urbanization and agglomeration economics were once prominent, their empirical limitations have become increasingly apparent. Greater territorial polarization and pervasive left-behindedness has underscored the need for a more inclusive territorial development approach prompting increased interest in understanding and addressing regional disparities to ensure more equitable economic growth. This article synthesizes the growing interest in territorial development, which has driven to the adoption of what are increasingly place-based and place-sensitive approaches to development. The article also emphasises the need for complementary between efficiency-driven and equity-focused interventions, while highlighting emerging topics in regional economics research, including the role of institutions, agency, and external megatrends such as the green transition. We conclude by advocating a place-sensitive approach that tailors policies to regional challenges, promoting economic potential, diversification, and inclusivity across all regions.
