Over the past 40 years of reform and opening up, China's booming economy and fast-growing Chinese market have provided valuable development opportunities for China's construction machinery industry to become bigger and stronger. After 40 years of development, China has become the country with the most complete categories of construction machinery products, outstanding advantages in serialization and complete sets, and the largest industry scale, providing engineering equipment support for national economic construction.In the historical process of reform and opening up, China's construction machinery industry has achieved fruitful technological innovation. In the past 40 years, the industry has achieved breakthrough results in research and development of new technologies, new structures, new processes and new materials. A large number of high-end construction machinery and major technical equipment, representing the most advanced level of technological development and capable of replacing imports, have been rolled off the production line one after another, becoming brand-new business cards made in China. At the same time, outstanding enterprises in the industry have taken advantage of the "the belt and road initiative" east wind to continuously expand overseas business and enhance their global service capabilities, providing equipment support for infrastructure construction in countries along the route. 

After 40 years of reform and opening up, the country has made great achievements. In the new historical process of reform and opening up, China's construction machinery industry must constantly break through the bottleneck of development, improve the quality of development, realize "three changes" in independent innovation, and truly realize the dream of becoming a powerful country in construction machinery manufacturing.
