Along with the development of trade globalization, the research on the relationship between total foreign trade import and ex- port and GDP of countries with different GDP levels is also the key to national economic develop- ment. In this paper, the cluster analysis of 16 countries was carried out by R according to the GDP of each country in 2012. Secondly, SPSS is used to test the Pearson correlation coefficient between total import and export and GDP of some countries in each category. In order to understand coun- tries of various economic levels and the correlation between these two indicators, a line chart was drawn. Subsequently, the data of some countries in each category from 1970 to 2016 were calcu- lated and mapped to explore the degree of dependence of each type of country on the internation- al market. Finally, the total import and export volumes of the higher GDP countries and the middle GDP countries are co-integrated with the GDP indicators.
