With the continuous development of emerging technologies such as big data，Internet of things，cloud computing and artificial intelligence，intelligence has a profound impact on the manufacturing and operation innovation of equipment products. China’s intelligent high-speed rail is one of the remarkable achievements. China’s high-speed rail continues to integrate and absorb the new generation of intelligent technology，which not only makes continuous breakthroughs and innovations in technology and management，but also makes the construction，equipment and operation fields develop together under the support of intelligent data. It also strides forward to a more intelligent，more efficient and more scientific high-speed railway innovation ecosystem. Based on the constituent elements of high-speed rail industry，this paper analyzes the structural characteristics of its innovation ecosystem，combs the literature on the construction of innovation ecosystem by intelligent high-speed rail in technology and management，and deeply explores the operation mechanism of the innovation ecosystem of intelligent high-speed rail. The research not only helps to expand the theory of innovation ecosystem，but also provides necessary scientific guidance for the management and operation of intelligent high-speed rail innovation ecosystem.
