China's High-speed railway (HSR) network had experienced rapid expansion during 2009 to 2013, and how the HSR expansion affects China's economy has been considerable concerned by both policymakers and researchers. Using firm-level data, this study accessed the effects of HSR on productivity distribution and resource misallocation among manufacturing firms. Incorporating difference in difference idea into a multilevel model, the results suggest significant misallocation rectifying effect of HSR at firm level. This effect is stronger for capital-intensive firms. City-specific analysis indicates that the effects of HSR on firm-level resource misallocation varies with city size, and firms grouped in small cities gain more misallocation rectification than those grouped in big and medium cities. Market potential, which is an important way through which the HSR affects efficient allocation of production resources, is found boost the marginal effect of HSR by reducing labor market segmentation and increasing agglomeration.
中国的高速铁路（HSR）网络在 2009 年至 2013 年经历了快速扩张，HSR 扩张如何影响中国经济引起了政策制定者和研究人员的极大关注。本研究使用企业层面的数据，探讨了 HSR 对制造业企业生产力分配和资源错配的影响。通过将差分法思想纳入多层次模型，结果表明 HSR 在企业层面具有显著的资源错配纠正效应。对于资本密集型企业来说，这种效应更强。基于城市的分析表明，HSR 对企业层面资源错配的影响因城市规模而异，与大城市和中等城市相比，小城市的企业获得了更多的资源错配纠正。市场潜力是 HSR 影响生产资源有效配置的重要途径，研究发现，市场潜力通过减少劳动力市场分割和增加集聚，提高了 HSR 的边际效应。
