中国茶产品国内贸易流通的互补性和竞争性分析

China Tea product competition and complementary analysis in home trade

本文利用贸易测算指标显性比较优势RCA、相对贸易优势RTA、贸易综合互补指数OBCij等指标对我国各区域省份茶产品比较优势、竞争优势以及茶产品贸易流通的竞争性和互补性进行了实证研究,结果表明:(1)浙江、安徽、福建、江西、湖南、广西、云南、海南具有显性比较优势,而湖北、广东、重庆、四川、江苏等省份茶叶不具有比较优势;其中,浙江、安徽、福建、江西、湖北、湖南、广西、云南、海南这些地区的茶叶具有相对贸易优势;江苏、山东、陕西、广东等地区的茶叶具有相对贸易劣势。(2)北京和上海分别与浙江、安徽、福建、广西、云南茶叶贸易存在互补性;安徽、福建分别与山东、河南茶叶贸易存在互补性;浙江、湖北、湖南、广西、四川、云南与陕西、甘肃、宁夏、新疆、内蒙古、西藏地区的贸易互补,这些地区之间茶产品贸易是互补的。(3)而江苏与浙江、江西、湖北、湖南,广东,海南,陕西,重庆之间存在贸易竞争性;安徽、福建、江西、湖南、湖北、四川、广东、重庆这些省份之间也是互相竞争关系,这些地区之间茶产品贸易是相互竞争性的。最后为我国如何根据区域特点更好地发挥区域之间的合作性提供了针对性的建议。
