This paper develops a conceptual and methodological framework for analyzing and measuring economic resilience. The operational definition of economic flexibility adopted in this paper is defined as the ability of an economy to ameliorate or mitigate the effects of negative shocks to which the economy may be inherently exposed. This paper also develops an index of economic resilience that covers four aspects of economic stability; Includes macroeconomic stability, market productivity at the micro level, governance and social development. The experimental findings of this study show that for the period under study during the years 1360-1393, when Iran has always been exposed to the negative effects of external shocks caused by the imposed war and economic sanctions,The economic flexibility has not been acceptable enough to curb the effects of these negative shocks and give the country higher economic growth and performance.
