Comparative structural approaches regarding relevant indicators of Input-Output analysis at macro and sectoral level: a case study of some European Union countries

Sectoral detailed analysis of the economy of a country is a difficult process, but important in the current context of globalization, in particular because of the complexity of interconnections between the branches, being known the role of investments and capital, but also trade, in GDP creation. Activities of national economies, as a whole, form a complex mechanism that deserves a detailed investigation, not only in terms of their past and current situation, but also to create useful models to forecast and predict, useful for decision-makers. In this research we used Input-Output (IO) statistical tables and various principles of the IO model and method to make a structural and comparative analysis of relevant economic indicators of economy, for Romania and some European Union countries, based on the Eurostat data (years 2000 and 2006).
