Abstract: 【Objective/Meaning】Tea production advantages and influencing factors of tea-producing provinces in mainland and China in 2009-2015 were analyzed to provide references for the provinces to make full use of their own advantages and enhance the industrial competitiveness.【Methods/Procedures】With comprehensive comparative advantage index, the tea production scale, efficiency, benefit and comprehensive advantage of provinces were analyzed, and the influence factors for tea production advantage were analyzed by grey correlation method.【Results/Conclusions】The ranking pattern of provincial tea production advantages had basically formed and been relatively stable.The scale, efficiency and benefit advantages of tea production in the studied provinces were in dynamic changes;and the effects of the influencing factors on the advantages of tea production in each province decreased in order:scale advantage>benefit advantage>efficiency advantage.The provinces with obvious tea production advantages mainly distributed at the north of Nanling, the south of Qinling-Huaihe, and the east of Hengduan Mountains.And, the tea-producing provinces were symmetrically distributed from east to west and had formed basic ranking pattern within the dominant zone.
