This paper measures and calculates the comparative advantage of China＇s natural rubber production,with the methods of the production index of concentration,efficiency advantage of comparative advantage index and comprehensive index respectively.The results show that from 2004 to 2008,China＇s natural rubber production concentration index,index of production efficiency and overall strength index strengths ranks in the middle,in comparison with the main producing areas of natural rubber,which does not have a comparative advantage,which is opposite to the main producing areas of non-natural rubber.In China＇s recent five years,the comprehensive advantages of the weighted average index value bit 0.0848,and China ranks the 21st in 25countriesor regions.
