“一带一路”倡议对中国茶叶出口的影响——基于渐进双重差分模型的实证分析

摘要/Abstract

摘要： “一带一路”倡议是促进中国茶叶出口的重大机遇,但是现有研究缺乏对其实际效果的系统评估。基于2009—2018年中国与40个主要茶叶进口国家和地区的面板数据,运用渐进双重差分模型评估了“一带一路”倡议对中国茶叶出口增长的政策影响。结果表明,在控制其他影响变量的条件下,“一带一路”倡议对于中国茶叶整体出口额增长具有一定的正向影响;进一步的产品异质性分析表明,“一带一路”倡议显著促进了中国绿茶出口的增长,但对红茶出口的作用尚不显著。此外,在控制变量中,国家和地区的人均GDP以及经济开放水平的提高也能够显著促进中国茶叶出口增长。最后对我国茶叶出口贸易如何把握“一带一路”政策机遇提出了对策建议。

关键词: 中国, 茶叶出口, “一带一路”倡议, 渐进双重差分模型

Abstract: The “Belt and Road” Initiative is a great opportunity for China's tea export. But the existing literatures are short of the evaluation of the policy effect. Based on the panel data of China and 40 major tea importing countries and regions, the difference-in-difference model (Generalized DID) was used to evaluate the promote effect of the “Belt and Road” Initiative to China's tea export. The results show that under the control of other variables, the “Belt and Road” Initiative had a positive effect to promote the growth of the export value of China's tea. Products heterogeneity analysis shows that the “Belt and Road” Initiative significantly promoted the export growth of green tea, but it had no significant effect on black tea. In addition, among the control variables, the improvement of per capital GDP and economic openness could significantly promote the export growth of China's tea. Finally, some suggestions were put forward for China's tea export trade to seize the opportunity.

Key words: China, tea export, the “Belt and Road” Initiative, generalized DID
