This paper expounds upon the current situation of China Railway's "Go Global" construction mode, the major challenges, and the new development trends of the large international engineering contracting market. Utilizing the Jakarta-Bandung high-speed rail project in Indonesia as an example, the innovation practice of construction mode in China Railway's "Go Global" strategy is deeply explored, and three development paths are presented: development toward a whole railway industry value chain from the integration of railway investment, construction and operation; a comprehensive development model of implementation for "railway + supporting industry"; and a development model of public-private-partnership (PPP) cooperation. Finally, this paper proposes safeguard measures from four aspects, namely construction of a public service platform in China Railway's "Go Global" strategy, enhancing the local development level, reinforcing the building of a talent team, and cultivating the concordance and integration capabilities for the whole railway industry value chain resource.
