Cost Control System of Cross-Border E-Commerce Based on Fractional Differential Equation

The fractional differential equation is used to quantify the cost management system of Chinese cross-border e-commerce enterprises. At the same time, the influence mechanism of this system is preliminarily explored in this paper. Then this paper makes quantitative and simulation tests on the balance and stability of the cost control system of cross-border e-commerce. At the end of the report, the impact of new laws and regulations on the cost control of international e-commerce in China is analyzed. The results show that multinational e-commerce can make Chinese export gain more significant development in expanding margin and intensive margin. It is more evident in developing marginal effect but lags in intensifying marginal effect.
