This article stems from the discrepancy between the lack of attention paid to industrial land policy by academics and the predominant thought among elected representatives and development agencies, i.e. that industrial land policy plays a key role in the creation of growth and new jobs. The article begins with a reflection on the literature, which stresses the need to develop knowledge on industrial land policies. To help fill this research gap, we have developed an exploratory piece of research on the theme of their spatial and economic effectiveness, on the basis of statistical analyses dedicated to seven countries. As regards spatial effectiveness, the results underline significant national differentials in terms of land consumption on the one hand, while highlighting the economic sprawl that affects France and Belgium on the other hand. As regards economic effectiveness, our results show that the impact of the development of economic estates on growth depends largely on regional contexts. In particular, the "intermediate regions" in western Germany stand out as belonging to a specific context where land policies seem particularly effective from an economic standpoint. By contrast, the economic effectiveness of industrial land policies requires readjustments in most "predominantly rural regions, close to a city".
