“一带一路”沿线国家设施联通对贸易利益的影响

以全球价值链（GVC）参与为视角，基于2005—2015年40个“一带一路”沿线国家与我国的增加值贸易数据，采用静态面板固定效应模型实证分析交通基础设施和通信基础设施对“一带一路”沿线国家贸易利益的影响。结果发现，加强交通和通信基础设施建设有利于提高一国出口中所包含的国内增加值，增进该国的贸易利益。作用机制研究表明，交通基础设施和通信基础设施都能够通过降低贸易成本促进贸易利益的提升，其中通信基础设施还能够通过提高贸易的时间效率对贸易利益产生积极影响。因此，“一带一路”沿线国家应以设施联通为依托，加强本国的交通和通信基础设施建设，把握参与国际生产分工的主动权，以实现共同发展繁荣。

Research on the Impact of Facilities Connectivity on Trade Benefits alone the Belt and Road Countries

From the perspective of global value chain (GVC) participation,based on the value-added trade data of 40 countries along the "Belt and Road" and China in 2005-2015,a static panel fixed effect model is used to give an empirical analysis on the impact of transportation infrastructure and communication infrastructure on the trade interests of the countries along the "Belt and Road".It it found that strengthening the construction of transportation and communication infrastructure is conducive to increasing the domestic added value included in a country's exports and enhancing the country's trade interests.The research on the mechanism of action shows that both transportation infrastructure and communication infrastructure can promote trade benefits by reducing trade costs,and communication infrastructure can also have a positive impact on trade benefits by improving the time efficiency of trade.Therefore,countries along the "Belt and Road" should rely on facilities connectivity,strengthen their transportation and communications infrastructure,and take the initiative to participate in the international division of labor in order to achieve common development and prosperity.
