Abstract:Based on the transnational panel data of 48 countries along the "Belt and One Road" from 2009 to 2018, this paper studies the total export trade effect, export trade effect of SITC products and intraregional trade effect of Chinese standard export under three types of standard cooperation, standard demonstration and standard dominance. The results show that Chinese standard export under the three types of models has a significant positive effect on export trade, the export trade effect of SITC products presents a significant heterogeneity, and there is a significant positive intraregional trade reciprocity effect among countries along the "Belt and One Road". The results show that in the process of implementing standards going global, China should pay attention to the coordinated promotion strategy of standard cooperation, standard demonstration and standard dominance mode, and strengthen the publicity of the reciprocal effect of standards export trade. Finally, according to the research conclusion, China should pay more attention to the strategy of Chinese standards export on the basis of establishing its own standards, gradually establish a high-quality standard system that matches the market demand of BRI, and promote the growth of export trade through the demonstration effect of standards. Let the countries along the "Belt and One Road" recognize that Chinese standard export is a favorable policy to achieve mutually beneficial trade and an important measure to practice a community of shared future for mankind.
