自由贸易试验区设立对中国数字贸易发展的促进效应研究

Research on the Promoting Effect of the Establishment of Pilot Free Trade Zones on the Development of China's Digital Trade

文章首先从理论上论述了自由贸易试验区促进数字贸易发展的内在机制,其次采用2007—2018年中国省级面板数据和多期双重差分模型实证检验了自由贸易试验区设立对数字贸易发展的促进效应及其机制。结果表明,自由贸易试验区的设立促进了我国数字贸易发展;区域异质性分析发现,相对于西部地区而言,处于东部和中部地区的自由贸易试验区设立对数字贸易发展的促进效应更显著,且中部地区自由贸易试验区设立对数字贸易发展促进效应最强烈;通过作用机制与渠道分析发现,自由贸易试验区的设立存在一个初始制度环境门槛,当初始制度环境太差,设立自由贸易试验区并不能有效促进数字贸易发展,而技术创新在自由贸易试验区促进数字贸易发展中发挥着显著的中介作用。最后,提出应将制度质量作为自由贸易试验区设立与发展的关键评价指标,积极发挥自由贸易试验区的制度创新与政策红利优势,着力推进大众创业万众创新,以技术创新推动贸易高质量发展。

This paper firstly discusses the internal mechanism of pilot free trade zones(FTZ)to promote the development of digital trade theoretically.Secondly,it empirically tests the promoting effect and mechanism of the establishment of FTZ on the development of digital trade by using China's provincial panel data from 2007 to 2018 and multi-period differential model.The results show that the establishment of FTZ has promoted the development of digital trade of our country.Regional heterogeneity analysis shows that compared with western regions,the establishment of FTZ in eastern and central regions has a more significant promoting effect on the development of digital trade,and the establishment of FTZ in central regions has the strongest promoting effect on the development of digital trade.Through the analysis of the mechanism and channels,it is found that there is an initial institutional environment threshold for the establishment of FTZ.When the initial institutional environment is very bad,the establishment of FTZ cannot effectively promote the development of digital trade.Technological innovation plays a significant intermediary role in promoting the development of digital trade in FTZ.Finally,it is proposed that the quality of institutions should be taken as the key evaluation index of the establishment and development of FTZ,and the advantages of institutional innovation and policy dividend of FTZ should be actively brought into play,and mass entrepreneurship and innovation should be promoted,so as to promote the high-quality development of trade with technological innovation.
