Assessment of Mutual Economic Relations the Countries of the World on the Basis of Input-Output Table

'Input-Qutput' table which was designed for solution of mutual relation(impact) problem is widely applied tool in the world for conducting economic analysis and forecasting. One of the most important problem of our today’s world is to prevent financial-economic crises in several countries of the world and especially in Eurozone countries where it is still ongoing. Input-output balance tables were prepared by modifying input-output table based on relevant economic indicators of the biggest countries of the economy of the world as well as simulations were conducted by designing several balance models(mutual impact of GDP and change in general output of countries, mutual impact of added value and prices, mutual impact of GDP and work places). Level of coverage of relevant indicators used in analysis on the countries of the world were tested on the basis of statistic methods and assessed. It was identified that, level of confidence of the coverage of designed model on world economy is higher than 95%. These models enables to analyze and forecast possible changes in world economy caused by changes took place in economic conjecture of other big countries of the world, especially in USA, Japan, Germany and China. It should be noted that, model’s system was automatized in EXCEL system with the purpose of simplifying simulations and conducting analysis and increasing efficiency on the usage of models
