Abstract：Based on the crosscountry panel data from 2009 to 202O，we use the DID method to test whether the Belt and Road Initiative has optimized the trade competition and complementation between China and co-building countries. The results show that the Belt and Road Initiative has significantly enhanced the complementation between China's exports and the imports of the co-construction countries，but has no significant impact on the export competition between China and the co-construction countries and the complementation between China’s imports and the exports of the co-construction countries. The promoting efect of the Belt and Road Initiative on the complementary relationship between China’s exports and imports of co-construction countries began to appear in the signing year of the cooperation documents， and has been growing over time. The results of heterogeneity analysis show that the Belt and Road Initiative plays a greater role in promoting the complementation between China's exports and imports from the co-construction countries with high level of economic development and high institutional quality. Further tests show that under the background of the Belt and Road，the effect of trade creation generated by production capacity cooperation，cultural exchanges and the improvement of trade facilitation between China and co-construction countries is greater than the effect of trade substitution.
