中国茶叶区域品牌发展的空间效应

Spatial Effect of Tea Regional Brand Development in China

基于2010—2019年中国茶叶区域品牌价值面板数据,运用泰尔指数和变异系数测度茶叶区域品牌发展水平的地区差异,利用OLS模型和空间杜宾模型检验茶叶区域品牌发展水平的β收敛特征,深入分析我国茶叶区域品牌发展演化趋势。结果表明,从时间来看,中国茶叶区域品牌发展水平呈平稳上涨阶段,其泰尔指数和变异系数呈下降趋势。从四大茶区来看,西南茶区茶叶区域品牌发展趋势基本与全国水平一致,其地区差异长期维持较低水平,发展速度呈空间β收敛特征,空间溢出效应弱;江南茶区长期高于全国平均水平,但其地区差异较大,发展速度呈空间β收敛特征,β收敛速度约为全国平均水平的60%;华南茶区茶叶区域品牌发展呈N型上涨趋势,但其地区差异最大,发展速度不存在空间β收敛;江北茶区的茶叶区域品牌发展长期低于全国平均水平,其地区差异小,发展速度呈空间β收敛特征。

Based on the panel data of tea regional brand value in China from 2010 to 2020 in china,the paper measured the regional differences of tea regional brand development level by using Theil index and variation coefficient,then tested theβconvergence characteristics of tea regional brand development level through OLS model and Spatial Dubin model,analyzed deeply the evolution trend of tea regional brand development in China.The results showed that from the time point of view,the development level of tea regional brand in China showed a steady upward stage,and its Theil index and coefficient of variation showed a downward trend.From the perspective of the four tea areas,the development trend of tea regional brands in southwest China was basically consistent with the national level,its regional differences had remained at a low level for a long time,the development speed was characterized by spatialβconvergence,and the spatial spillover effect is weak.The tea regional brands in Jiangnan had been higher than the national average level for a long time,but its regional difference was large,the development speed showed the spatialβconvergence characteristic,theβconvergence speed was about 60%of the national average level.The development of tea regional brand in south China showed an N-type upward trend,but the regional difference was the largest,and there was no spatialβconvergence in the speed of development.The development of tea regional brands in Jiangbei had been lower than the national average level for a long time,the regional difference was small,the development speed presented the spatialβconvergence characteristic.
