Research On China’s Tea Export Growth Based On The Ternary Margin

China’s tea history has a long history and is also the earliest agricultural product for export trade.Since the Western Han Dynasty,tea has been traded for nearly two thousand years and is now sold to more than 100 countries and regions around the world.In 2017,China’s tea exports reached 355,000 tons,and exports amounted to 1.61 billion US dollars,accounting for nearly 20% of global tea exports.It is extraordinary significance for us to study the growth of tea export trade under the economic background of “Belt and Road” and promoting agricultural economic development.This study mainly decomposes the influencing factors of China’s tea export growth through the ternary marginal method.Firstly,it analyzes the development of tea industry and the growth of export trade.Then it analyzes the three-dimensional margin of tea export from three angles: the change of the kinds of the tea exported,the change of tea export market and the value of tea has changed.The study found that the main markets for tea exports in China are located in Africa,the Russian Federation,the United States,Japan and the European Union.The main kinds of export tea are black tea and green tea,and the growth of tea exports mainly depends on the expansion of marginal pull,intensive margin,Since 2017,the growth of tea export mainly relying on price margins,and the marginal contribution of quantity is small.The article further use the data of the top 30 countries(regions)of China’s tea exports by the gravity model.An empirical study of panel data was done.The study found that the factors affecting the ternary margin are different,and are closely related to the economic and technical standards of the export destination countries and the level of China’s tea production.Finally,according to the analysis results of the article,the promotion of tea export trade is proposed.The suggestions should focus on the marginal growth of margins and prices,and promote the growth of tea export trade.
