中文摘要：

哈萨克斯坦是中亚地区综合实力最强、与中国经贸关系最密切的国家。自从共建“一带一路”的战略构想提出以来，两国的自由贸易区和便利化建设受到广泛关注，却鲜有对其经济影响的研究。本文利用GTAP模型定量测算了两国关税削减和贸易便利性提升的经济影响。研究发现，关税削减只能使中国的GDP增长0．02％，哈萨克斯坦为0．68％。然而，如果将时间成本这一贸易便利化措施纳入考虑，中国的经济增长幅度将增加9倍，达到0．17％，哈萨克斯坦的经济发展也将得到极大促进。这说明贸易便利化对经济的促进作用大于关税削减．忽视时间成本的研究将严重低估中哈贸易自由化的正面影响。从产业层面看。中国绝大多数产业的贸易和产出都将受益，只有采掘业和服务业出口小幅度受损0．1％左右。采掘业产出下降0．01％；哈萨克斯坦的大部分产业也从中获益，尤其是纺织服装出口由于关税削减而得到较大扩张。

英文摘要：

As the largest economy in Central Asia, Kazakhstan also keeps the tightest connections with China, and the connection has been strengthen since the New Silk Road Plan was raised. However, a few literatures have been found talking about the NTBs and trade facilitation between China and Kazakhstan while many paying attention on the cut of tariff. In order to assess the economic impact, this paper utilizes GTAP model and takes the time value into account. The results show that the tariff cut between the two countries will benefit China and Kazakhstan＇ s economy by 0.02% and 0.68%, but the benefit will be enlarged to 0.17% and 3.30% if the time cost could be cut at the same time. This implies that the trade facilitation is an important barrier to overcome and researches ignore the time value may underestimate the impact.
