Research on National Cross-border E-commerce Trade Innovation and Development Strategy in the Context of Digital Economy

Cross-border e-commerce is divided into export cross-border e-commerce and import cross-border e-commerce. Based on the fact that the development of China’s export cross-border e-commerce trade is dominant at present, this paper takes the diamond model and the theory of platform economics as the basis of model construction and selects the trade demand, human resources, cross-border platforms, cross-border payment and cross-border logistics to constitute the influencing factors of cross-border e-commerce system variables. Among them, for the influence mechanism of e-commerce development level on cross-border e-commerce trade, a cross-border e-commerce development level measurement index system has been established. Utilizing the entropy value method and comprehensive index method, the measurement value of the cross-border e-commerce development level is obtained. The order of importance of each influencing factor is determined using principal component analysis. The trade gravity model is introduced, combined with cross-border e-commerce export monitoring data, to carry out the model smoothness test and regression model solving. From the regression results, the P-values of the t-test statistics of independent variables InGDP_c InR_i are 0.162 and 0.806 (>0.05), respectively, indicating that the influence of these two independent variables on the dependent variable is not significant. That is, China’s GDP and whether to join the “The Belt and Road Initiative” have no significant impact on the scale of China’s cross-border e-commerce trade. According to the regression results of the model, GDP, the coefficient of population size and the number of Internet users are highly positively correlated with the scale of cross-border e-commerce trade of the country, and the innovation of cross-border e-commerce trade can be based on the coefficient of GDP, the coefficient of population size, the number of Internet users and other aspects.
