Abstract: China is the largest tea producer and an important exporter. However, the development of small scale tea enterprises in the large tea market poses a challenge to the international status of Chinese tea. Based on the theory of international competitiveness and using the UN Comtrade to link sample data in the WITS database, this paper calculated the international market share of Chinese tea, the intra-industry trade index, the comparative advantage index, and export price, and compared them with those of other world leading tea exporters. Results show that China has some comparative advantage in the global tea market with a decreasing trend. The export price of tea shows a trend of falling first and rising steadily and the value of Chinese tea has been recognized in the international market. After the implementation of the green trade barriers, China’s tea industry has formed a new asset ownership advantage and entered a benign development of intra-industry trade model. The advantages and disadvantages of China’s tea industry coexist and the key to the improvement of international competitiveness of Chinese tea lies in the improvement of quality and brand recognition. Therefore, to improve the international competitiveness for China’s tea industry, this paper suggests: to establish the research and development system with tea enterprises as the main body, to speed up the legislation of tea technology, to implement the strategy of brand promotion vigorously, to enhance the self-discipline level of tea organizations, and to increase the support for tea industry.
