Extracting from the theoretical framework and literature, two hypotheses based on party-political congruence and interest compatibility are formulated. The analysis of party-political congruence and executive overlap as determinant shows that there are big differences in the level of congruence between provincial regions of The Netherlands. However, the analysis likewise shows that party-political congruence solely attributes little to the extend of regional cooperation in EU-affairs. This resulted in the determinant of party-political congruence being refuted. However, when we reformulate and add the dimensions of party ideology, executive (party) network and coalition agreements to the equation, political congruence increases in validity as supporting factor for regional cooperation. The analysis of interest compatibility shows that that there are significant differences in the degree of interest compatibility between different provinces within different regions in The Netherlands. This variation results in significant different outcomes when it come to regional cooperation in EU-affairs. Hence, interest compatibility is accepted as determinant factor. When further scrutinizing, it appears that social, economic and geographical provincial characteristics are important conditions for interest compatibility. In conclusion to the thesis' main question, it’s the compatibility of provincial interests and proactive executives which are the drivers behind regional cooperation. When provinces are characteristically alike, have well-connected executives, pro-European parties in the regional assemblies and European funds maintain well-defined criteria, regional cooperation can be a logical phenomenon in The Netherlands.Show less
