Abstract. The necessity to identify a new agenda for economic science results from the specific feature of this discipline and the insufficiencies of traditional approaches generated by the limits of the classic economic theories, from the necessary reevaluations in the national circumstances context and world modified ones. Starting from this findings we proposed ourselves to relevate the opportunity of a new paradigm in economy which could permit possible achieving of a new modern vision. One of the research challenges in the economic science field is reconstruction of the relation between state and economy, enlightening a new theory on the economic role of the state, renovating the macroeconomic theories and rethinking the objectives and action instruments specific to economic polices. To this goal we analyzed the main evolutions in economic and political plan and their influences of the power and intervention forms of the state. On the bases of studies and works assigned to this issue, we made critical analyzes of the main opinions referring to the dimensions and implications of the „New Economy” and to the possibility the developed countries to cross a stage or a phase in the evolution of capitalism. The last part of this study is dedicated to the debate on convergence possibility of the national political and economic systems toward an unique liberal model.
