黄河流域高铁建设对旅游经济绿色发展效率的影响研究
Study on Impact of High Speed Railway Construction on Green Development Efficiency of Tourism Economy in Yellow River Basin
为分析黄河流域高铁建设对旅游经济绿色发展的影响效应,构建超效率SBM模型测度黄河流域90个区域2005—2023年旅游经济绿色发展效率,采用多期双重差分模型实证检验高铁开通的净效应,并系统分析高铁建设促进旅游经济绿色发展的内在路径。结果表明:基准DID与PSM-DID模型结果显示,高铁开通对节点区域旅游经济绿色发展效率具有稳定促进作用。高铁建设的促进效应存在一定区域差异,呈现出从上游到下游依次递增的梯度特征,上游地区促进效应相对有限,中游地区效应显著,下游地区受益较大。高铁建设通过推动产业结构高级化与科技创新投入,进而促进旅游经济绿色发展,共同构成了高铁驱动旅游经济实现绿色发展的内在动力。未来应进一步优化高铁网络布局,制定差异化旅游经济发展政策,推动产业升级并加大科技创新支持力度,加快构建旅游经济绿色发展新格局。
To analyze the impact effect of high speed railway construction on the green development of the tourism economy in the Yellow River Basin, a super-efficiency SBM model was constructed to measure the green development efficiency of the tourism economy in 90 regions of the Yellow River Basin from 2005 to 2023. A multi-period difference-in-differences model was adopted to empirically test the net effect of high speed railway opening, and the internal pathways of high speed railway construction promoting the green development of the tourism economy were systematically analyzed. The results show that both baseline DID and PSM-DID model results indicate that the opening of high speed railway has a stable promoting effect on the green development efficiency of tourism economy in node regions. The promoting effect of high speed railway construction has certain regional differences, showing a gradient characteristic of sequential increase from upstream to downstream; the promoting effect in upstream regions is relatively limited; the effect in midstream regions is significant, and the downstream regions benefit greatly. High speed railway construction promotes the green development of the tourism economy by driving the advancement of industrial structure and scientific and technological innovation investment, which together constitute the internal driving force for high speed railway to drive the tourism economy to achieve green development. In the future, it is necessary to further optimize the high speed railway network layout, formulate differentiated tourism economy development policies, promote industrial upgrading, strengthen support for scientific and technological innovation, and accelerate the construction of a new pattern of green development of the tourism economy.
