The influence mechanism of the innovation factors flow on the industry is analyzed by means of the"driving force-pressure-state-impact-response"analysis framework of the DPSIR model from the perspective of“space of flows”based on HSR development.The PLS(Partial Least Squares)structural equation model is adopted to verify the impact of the pathways of the DPSIR model.The High-Speed Rail Flow Space's Innovative Element Flow Industry Effect Index and its spatial distribution is calculated by the entropy weight-TOPSIS method.Additionally,the the grey relational analysis method is used in conjunction with industrial location entropy to assess the interrelation of various industry impact effects.The study reveals that high-speed rail drives the flow of innovative elements between regions,subsequently influencing industrial structures and impacting regional economies.Significant differences are observed in the regional industry effects of innovative element flow within the high-speed rail flow space.Furthermore,the effect of innovative element flow in the high-speed rail"flow space"varies across different industries.This research enhances the measurement methods for assessing the high-speed rail"flow space"effect and empirically validates the impact of innovative element flow on industries,providing valuable insights for high-speed rail planning and industrial innovation development.
