报告摘要：

This paper evaluates the impact of State aid granted to local authorities in France through the French broadband scheme Plan France Très Haut Débit. We exploit a rich dataset containing information on fiber deployment, State aid, and socio-demographic characteristics of more than 34,000 municipalities in mainland France over 2014-2019. First, we study the determinants of entry into fiber and evaluate the plan’s efficiency using a structural model of entry. Second, we assess the impact of State aid on broadband coverage. We find that the plan was relatively efficient in solving a market failure – low coverage in low-density areas – but at the cost of some crowding out. The plan also helped increase fiber coverage in aided municipalities in the early stages of fiber deployment.
