First of all, the development of high-speed rail in China is beneficial to the development of world traffic. China's high-speed rail development has made universally recognized achievements. The export of high-speed railway, communication, electric power and other service products rose to the national strategic level. It is the general trend for China high-speed rail products to enter the international market. However, due to various factors, China high-speed rail enterprises are facing multiple challenges and risks in the process of opening up the international market, and the road to opening up the international market is full of bumps. With the rapid development of high-speed rail in China, its influence in the world is more and more extensive. More and more developing countries have started or planned to build high-speed railways. ? The success of high-speed rail in China not only brought the development of high-speed rail in the world into a new era, but also set off the climax of the second high-speed rail construction in the world. The world rail transit is undergoing profound changes.
Secondly, it is conducive to narrowing the traffic gap between countries. The absolute gap between the total transportation volume and transportation facilities in various countries is still very large, and there is a trend of further expansion. With the unbalanced development and changes in all aspects of national development, various factors that lead to unbalanced traffic development are more or less playing a role, and the resultant force of various factors has produced a gap in degree. The transportation development between countries is changing with each passing day. Although the gap between land transportation is narrowing in recent years, the gap between sea transportation and air transportation is further widening, and the gap between countries in transportation development is still widening. First of all, it is urgent to solve the phenomenon of excessive imbalance in traffic development between the east and the west of China. The only way is to speed up the development of traffic in the west as soon as possible. Secondly, China's investment in the transportation infrastructure of third world countries is also beneficial to the development of the world.
