摘要
文章在城市数据库进出口数据的基础上,主要通过双重差分模型(DID)实证分析自贸区设立对城市贸易活动的影响效应,进而分析自贸试验区对城市的经济带动的效果。通过实证研究发现:第一,自贸试验区的设立确实有助于推动所在城市的进出口贸易增长;第二,自贸试验区的设立对城市进出口贸易的促进作用呈倒U型趋势,即其边际效应呈现先升后降的特征;第三,自贸试验区的设立对邻近城市的贸易有一定的虹吸效应,邻近城市的贸易进出口受自贸试验区的制度创新效应影响。因此,我国应在双循环新发展格局下,一方面要继续发挥自贸试验区制度创新的功能效应,培育增进贸易的新动力和新优势。另一方面,要增强自贸区的空间联动与协调,合理布局自贸试验区邻近城市的功能定位。
Based on the import and export data from the urban database from 2011 to 2017,the Dual Difference Model(DID)is used to empirically analyze the impact of the establishment of free trade zones on urban trade activities,and then to analyze the economic driving effect of free trade pilot zones on cities.Through empirical research,it has been found that,firstly,the establishment of free trade pilot zones does contribute to promoting the growth of import and export trade in the city where they are located.Secondly,the establishment of free trade pilot zones has an inverted U-shaped trend in promoting urban import and export trade,with its marginal effects showing a trend of first increasing and then decreasing.Thirdly,the establishment of free trade pilot zones has a certain siphon effect on the trade of neighboring cities,and the trade import and export of neighboring cities are influenced by the institutional innovation effect of free trade pilot zones.Therefore,it is proposed that China should continue to play the functional effect of institutional innovation in the pilot free trade zone and cultivate new impetus and advantages to enhance trade under the dual cycle Dual circulation.On the other hand,it is suggested to enhance the spatial linkage and coordination of the free trade zone,and reasonably layout the functional positioning of adjacent cities in the free trade pilot zone.
