Abstract: As the bridge and link connected with other countries and regions, international business and economics has a very important position in international economic relations. Selecting representative indicators of international business and economics and economic growth, then choosing the indexes’ average growth of nearly 12 years as a starting point, this paper calculates and classifies foreign trade relative growth index(TGI) and foreign capital relative growth index(CGI) in Northest China through relative growth index model. The results show that the relative growing types of foreign trade and foreign capital in Northest China are entirely different. Further more, a comparative analysis between foreign trade growth and economic growth over the years indicates that there is high synchronism between them and foreign trade growth always acts as barometer. However, the same analysis between foreign capital growth and economic growth indicates that there is no obvious law and foreign capital growth has uncertainties and contingencies. Finally, generalized impulse response analysis shows that foreign trade and foreign capital both have significant effects on economic growth, but the extents are not the same. Variance decomposition of economic growth reflects contribution of each index. This article provides a new perspective for the study on the relationship among foreign trade, foreign capital and economic growth.
