茶叶区域公用品牌发展的空间非均衡与动态演进

Spatial Disequilibrium and Dynamic Evolution of Tea Regional Public Brand Development

基于2010—2020年中国茶叶区域公用品牌价值面板数据,运用Dagum基尼系数法和核密度估计方法分析中国茶叶区域公用品牌发展的空间非均衡与动态演进趋势。结果表明:中国茶叶区域公用品牌发展存在显著的空间非均衡性,茶区内差异由大到小依次为华南、江南、西南和江北茶区;中国茶叶区域公用品牌发展总体差异主要来自不同茶区间差异贡献;无论是全国还是四大茶区内部,茶叶区域公用品牌价值呈增长态势,但各产茶省份其茶叶区域公用品牌发展的绝对差异在逐渐扩大,其空间分布的非均衡程度在加大。针对茶叶区域公用品牌不同发展水平,提出了相应发展战略。

Based on the panel data of tea regional public brand value from 2010 to 2020 in China,this paper analyzed the spatial disequilibrium and dynamic evolution trend of tea regional public brand development in China by methods of Dagum Gini coefficient and kernel density estimation.The results showed that there was significant spatial disequilibrium in the development of tea regional public brand in China,the intra-regional difference from the largest to the smallest were South China,Jiangnan,Southwest and Jiangbei tea regions;The overall difference in the development of tea regional public brand in China was mainly due to the difference contribution of different tea regions;Whether No matter in the whole country or in the four major tea regions,the value of tea regional public brand was increasing,but the absolute difference of the development of tea regional public brand in each tea producing province was gradually expanding,and the disequilibrium degree of its spatial distribution was increasing.In view of the different development levels of tea regional public brand,the corresponding development strategies were put forward.
