This paper uses the Revealed Comparative Advantage (RCA) index, Export Similarity index and Gray Model to analyze the competitiveness and complementarities of the software industry between China and India. The results show weak competitiveness of China and India’s software products in the main export markets; therefore it will be enhanced in the long-term. The software industries of the two countries are highly complementary. Therefore, China and India should strengthen cooperation in this industry to seek more benefi ts.展开更多
