This book examines the economic interconnections of the Greek economy at a macro and micro level, allowing it to explore both the economic relations between the various sectors and the interconnections of various companies and overlaps in management boards. Two approaches are used to quantify interdisciplinary and cross-sectoral interfaces: the traditional input-output analysis approach and the influence and information flow approach through network analysis. The book's first part presents the current conditions and the economic interconnections within the Greek economy. In the second part, during the analysis of microeconomic interconnections between individuals and companies, a much more thorough presentation of the economic interconnections of Greek companies is established. Finally, the book's third part presents how the Greek economy must transform its production prototype under structural constraints and opportunities for economic diversification and inclusive growth and under the pressure of economic shocks and uncertainty.
