贸易壁垒如何影响经济高质量发展?

How Trade Barrier Effects High-quality Development of Economy?

采用2007—2018年258个地级市的面板数据,实证分析贸易壁垒对我国经济高质量发展的影响。结果表明,贸易壁垒对经济高质量发展的影响存在倒“U”形特征。机制检验发现,贸易壁垒通过要素流动抑制了经济高质量发展。异质性分析表明,贸易壁垒对东部地区经济高质量发展具有抑制作用,而对中、西部地区经济高质量发展的影响存在倒“U”形特征。

Using panel data from 258 prefecture level cities in China from 2007 to 2018,this paper empirically analyzes the impact of trade barriers on high-quality economic development.The results show that trade barriers have an inverted“U”effect on high-quality economic development,and the mechanism test shows that trade barriers restrain high-quality economic development through factor flow.Heterogeneity analysis shows that trade barriers have a restraining effect on high-quality economic development in eastern China,but have an inverted“U”shape in middle and western China.
