Analysis of different branches of the Belgian economy shows that they can have divergent evolutions. The fact that they are affected in different ways by specific events (so-called shocks) and by economic policy measures is well known. However, we also know that these branches do not develop autonomously and that there are significant interdependencies between them.
This twofold assessment gives rise to sectoral and intersectoral analyses, in order to:
demonstrate both the specificities of each branch;
study the relationships between the different branches.
In this context, the Federal Planning Bureau is responsible for:
drawing up five-yearly input-output tables within the framework of the National Accounts Institute;
developing environmental satellite accounts and social accounting matrices, which enhance analyses with qualitative components.
