From the Introduction:

The objective of this paper is to propose a new impact analysis system for the acceding countries which is based on annual supply and use tables. The main benefits of the new data base are the disaggregation of 59 branches and the closer reflection of statistical sources. This new data base will allow a profounder assessment of Structural Funds interventions than in the past. The annual submission of supply and use tables will enlarge the potential for analysis and follow up of actual interventions.
