Research on the Pattern of Technical Service Innovation of Rail Transit Industry based on Industry Chain Viewpoint

The complete industrial chain and unique technical service characteristics have formed in the rail transit industry in China. In this paper, we study the existing technical service pattern of this industry from the viewpoint of industrial chain. We also discuss the pattern of technical service innovation from up, mid and down-stream of industrial chain respectively and analyse its evolution trends. Analysis demonstrates that industry alliance and collaboration innovation will be the important developmental direction of the pattern of technical service innovation, which should be helpful for continuous innovation of rail transit technical
