In May 2019,China Economist conducted a questionnaire survey of economists on the impact of CR Express on the four aspects of the Belt and Road, international trade, crossborder electronic commerce and industrial upgrading. Survey reveals that, firstly, CR Express and the Belt and Road can form a good mutual promotion relationship, but low security trust among countries along the line is the most important factor restricting the development of this relationship. Secondly, CR Express has a net growth effect on the total volume of international trade in China, especially in the northwest region, and is conducive to improving the trade imbalance between China and Europe. it also faces problems such as low efficiency of customs clearance and low return rate caused by European export control of hightech products to China. Thirdly, CR Express with low transportation cost has provided favorable conditions for the development of crossborder ecommerce in Central Europe and Asia, but its long transit time has affected its promotion. Finally, although CR Express can promote the industrial upgrading of China by optimizing the industrial layout, especially in the western region, it also has some problems, such as smallscale action for hightech industries, vicious competition and government intervention crowding out resources for industrial technological innovation.
