Approaching regional openness through measures of specialization and spatial market shares: experimentations with micro-data on enterprises

Abstract

In this paper, I present the results of ongoing experimentations with micro-data data of firms in order to develop better insights into the economic specialization and openness to trade of regions. Using newly developed indicators, one based on Huff-like models and another on Marcon and Puech's M function, I explore the possibilities offered by building analyses on the basis of point data instead of the classic regional aggregations.
