Survey of international business cycle and it's transfer from a country to another country is very important and Considering that business cycle synchronization can affect the international economic relations of the countries, a proper understanding of the economic activities effect of the trading partners on The business cycle fluctuations is important.. Nowadays, economists, in spite of the cycle fluctuations in macroeconomic activity as well as the emergence of industrial economies, collect data to describe and analyze these fluctuations. To this end, in this study, with the data of 19 selected countries of the MENA region and the econometric approach of the compilation data, we examine the effects of trade intensity on the business cycle synchronization of these countries during the period 1998-1999. The results of the research show that trade intensity is effective on the business cycle synchronization of the studied countries. On the other hand, with respect to the small coefficients of the production structures' similarity variables, this variable has little effect on the business cycle synchronization of these countries, in this case There are positive and negative relationships between intra-industry trade and the synchronization of business cycles. Also financial policies have a greater impact on business cycle synchronization than monetary policy. Among the examined influential variables, the most effective factor on the business cycle synchronization of Mena countries is intra-industry trade factor.
