高铁开通对出口贸易的影响及对策研究——以陕西省为例

Research on the impact of the opening of high-speed railway on export trade and countermeasures:Taking Shaanxi province as an example

高铁的建设开通对我国对外贸易发展具有巨大的推动作用,但目前还缺乏陕西高铁开通对城市出口贸易的影响及机制分析。本文使用2008-2022年陕西省城市统计数据结合多期双重差分模型测度发现高铁开通总体上有利于促进陕西城市出口贸易发展,中介效应检验发现高铁开通能够通过增加第三产业人员就业,降低单位运输成本来提高城市出口贸易。因此提出了陕西省应该重视高铁在开放型经济中的作用,提高对外开放水平,深度融入共建“一带一路”大格局等相关对策建议。

The construction and opening of high-speed railroad has a great role in promoting the development of China's foreign trade,but there is a lack of analysis of the impact of the opening of high-speed railroad in Shaanxi on the city's export trade and the mechanism.This paper uses the 2008-2022 urban statistics of Shaanxi Province combined with multi-period double-difference model measurement to find that the opening of high-speed rail is generally conducive to promoting the development of urban export trade in Shaanxi,and the mediation effect test finds that the opening of high-speed rail is able to improve urban export trade by increasing the employment of people in the tertiary industry and reducing the unit transportation cost.Therefore,it is proposed that Shaanxi Province should emphasize the role of high-speed rail in the open economy,improve the level of opening up to the outside world,and deeply integrate into the pattern of"One Belt,One Road"and other related countermeasures.
