This paper presents the regionalisation methodology followed to build a regional database for RHOMOLO, the regional computable general equilibrium model developed by the European Commission to evaluate the impact of Cohesion Policy. This report describes the methodology used to develop two sets of regional Social Accounting Matrices for the EU-28 at NUTS 2 level, according to both the NUTS 2006 and the NUTS 2010 classifications. The starting point is the set of national SAMs developed for the model by Álvarez-Martínez and López-Cobo (2016). The national SAMs are subsequently regionalised by means of non-survey techniques using the available regional statistical data from Eurostat, inter-regional bilateral trade flows developed ad hoc for this project and inter-regional transport cost data from the TRANSTOOLS project. The initial regional data prepared for RHOMOLO v2 included only the EU-27 and NUTS 2006, but following the adhesion of Croatia to the European Union on January 1st 2013, in this paper we also include a national SAM and two regional SAMs for Croatia.JRC.B.6-Digital Econom
