中国茶叶消费研究——基于饮茶习惯双向变化分析

A New Framework for the Research of Tea Consumption: Based on theTwo-way change of Tea Drinking Habit

利用CKB的截面数据,对中国10个地区19786名消费者饮茶习惯的变化情况进行统计分析,并对不同收入、不同年龄层的消费者饮茶习惯变化展开对比分析。结果表明,中国消费者的饮茶习惯随着时间的推移发生变化,饮茶习惯存在着偶尔饮茶和经常饮茶等不同程度的分布,饮茶习惯变化大多要经过偶尔饮茶这一中间阶段;饮茶群体的结构组成变化,可能会由于采用整体饮茶率这一宏观指标而被掩盖,从而忽略了饮茶习惯的个体变化及其背后的机理研究。在此基础上,提出要关注饮茶习惯的双向变化,尤其是关注偶尔饮茶这一茶叶消费的中间形态。

Based on the panel data from China Kadoorie Biobank database,the change of drinking tea habit from 19786 samples in 10 regions of china were analyzed,and a comparative analysis was made on changes of drinking tea habit in different age and income subgroup.The results show that the drinking tea habit change over time,and majority of change of drinking tea habit just go through the intermediate stage of occasional drinking tea.The change of structure for tea consumers may be concealed by using the tea drinking rate,and the individual changes in drinking tea habit could be ignored.So the bidirectional change of tea drinking habit should be pay attention to.
