Over the 40 years following the Reform and Opening-up, how does China manage to transform its major infrastructure from lagging behind to leading globally in such a short time? This question not only offers valuable practical insights but also poses a significant theoretical inquiry. By employing a comparative research approach, the implementation experiences of major infrastructure projects in China was systematically reviewed, developing theoretical insights in areas such as institutions, technology, management, finance and ideology. The feasibility of promoting these experiences internationally was also analyzed. The Beijing-Shanghai High-Speed Railway with overseas high-speed rail projects was further contrasted to illustrate the applicability and effectiveness of China's infrastructure development experience. It is explored how to provide Chinese experiences and solutions to the global infrastructure market and offers references for Chinese enterprises, particularly those involved in Belt and Road infrastructure projects, as they enter the international market.
