Romania's integration in the European Union implies, apart the complex process of policy transfer, the learning of new modes to make policies characteristic to a multi-level governance and partnership culture. Of the different levels of governance of the European model, the regional level ("regional governance") most faithfully reflects, in our opinion, the complexity of reconfiguring the role of state in economy, at the beginning of this new millennium, in the European Union space and presents the highest practical importance for Romania, as a new Member State of the European Union, for, at the regional level, the structures are more flexible and the good practices are more rapidly assimilable. The selection of the best regional growth and development economic policies, the choosing of the objectives out of a series of competing options, the calibration in time and space of powers, roles, capabilities, and responsibilities and the encouragement of the win-win solutions call upon the choice and combination of some appropriate and efficient instruments. Representative for the new context, the regional growth and development policy must integrate, in Romania too, more knowledge, more creativity, new combinations of capabilities and new fields of expertise. This paper presents preliminary research results afferent to the post-doctoral research project: "Growth and regional development economic policies. Challenges for Romania in the context of economic-financial crisis and European model integration", carried out in the project "Economic scientific research, reliance of human welfare and development in European context", the Romanian Academy, "Costin C. Kiriţescu" National Institute for Economic Research, project financed for the 2010-2013 period from the European Social Fund (EFS) and implemented by the Romanian Academy, "Costin C. Kiriţescu" National Institute for Economic Research, in the period of time 1 December 2010 - 30 November 2012, coordinator: Professor Dr. Valeriu Ioan Franc. The question we intend to answer, in the present phase of our research, based on the comparative analysis of the decentralisation systems of several Member States of European Union, respectively on the analysis of the regional disparities existing at the European Union level and of the effects of the economic integration, is - to what extent the capabilities of the regional policy should rather be concentrated in the hands of regional authorities or of the European Union than to be left individually to the Member States which should conceive their own regional policy? What we intend in this paper, based on the analysis of some experiences to decentralize the capabilities of economic policy at the European Union level, is to identify the regional implications of the interconnection of decentralization, centralization, respectively supra-nationalization tendencies and, implicitly, the analysis of the way to reconfigure the role of state in economy at the regional level, in the context of integration in the European model. The examination of the way to reconfigure the role of state in economy at regional level requires the review of the allocative, distributive, and regulating roles of the state from a regional perspective, the analysis, on one side, of the decentralization of economic policy capabilities from the national level to the regional level (for example, national level: pure public goods supply, for instance, national defence and the centralization of fiscal policy capabilities in order to achieve macroeconomic stability and revenue redistribution; regional level: mixed public goods supply, for instance, waste collection and community policy), on the other hand, the centralization/decentralization of regional capabilities at the European Union level.
