绿色贸易壁垒与茶叶出口的影响因素研究

ABSTRACTIn recent years,developed countries frequently update the standards of green barriers,which greatly affects the export of our products.Especially in the aspect of tea,the greenstandards of tea importing countries are constantly improving,which greatly restricts the exportof China's tea.Yunnan Province,as a big tea Province,has not been spared.In recent years,when the green trade barrier strengthens the standard,the tea export volume of YunnanProvince shows an obvious downward trend,and the green trade barrier has become the mainobstacle to the tea export of Yunnan Province.Based on the research results of relevant literature at home and abroad,this paper analyzes therelated concepts of green trade barriers and explains the impact of green trade barriers on teaexport through different aspects.Then the tea planting and export status of Yunnan Province areanalyzed.Finally,on this basis,the use of empirical analysis to draw relevant conclusions.Thispaper selects the relevant trade data of Yunnan's top 10 tea export countries from 2005 to 2019to test the stationarity and cointegration of the data,and then through the establishment ofmultiple regression model to explore the impact of green trade barriers on Yunnan's tea export.The empirical results show that the number of domestic tea products with pesticide residuerestrictions has a positive role in promoting the export of tea in Yunnan Province,while thenumber of foreign tea products with pesticide residue restrictions has a negative effect on theexport of tea in Yunnan Province.Finally,the paper puts forward correspondingcountermeasures and suggestions for the impact of green trade barriers on tea export in YunnanProvince.KEY WORDS:green trade barrier tea export,influence factor
