Abstract: The extended trade gravity model is used and the multinational panel data from 2008 to 2017 are selected to explore the influencing factors of China's export of sporting goods along "the Belt and Road" countries. "The Belt and Road" country's theoretical export value of sporting goods in 2017 is measured. Through the ratio of the actual export value to the theoretical export value, the export potential of sporting goods in 48 countries is classified.The results show that:the GDP of bilateral countries, the scores of political stability and absence of violence/terrorism of the exporting countries, the degree of openness of the exporting countries, and whether or not they join the WTO, have the positive effects on the export of sporting goods.The distance between the two countries hindered on the export of sporting goods. Among the 48 sample countries in the study, 19 countries have great potential, and China's export to them is far from enough to meet the demand, leaving a large market space.11 countries are potential pioneers, and China's sports goods trade with them can be further explored to expand export markets; 18 countries are potential re-models, with limited trade potential from China.It is believed that it is necessary to continue to strengthen the positive trade factors, eliminate trade barriers, and cultivate new energy for the growth of sports goods foreign trade with high-quality sports goods.
