Abstract

The high-speed railway (HSR) performance has drawn considerable attention from international scholars and policymakers. One heatedly-discussed topic is measuring HSR efficiency and its important determinants, particularly HSR organizational structures. The main contribution of our research is the adoption of the multi-stage Network Data Envelopment Analysis (DEA) and Tobit Model, which provides a rational and coherent method to address this issue.

We select the dataset from main HSR countries during the period of 2009–2018, and rank the efficiency of HSRs of different countries. Subsequently we examine the relationship between HSR efficiency and characteristic determinants, along with geographical and economic indicators that may influence the model.

The results have revealed the HSR productivity difference do exist among countries. Overall, Asia's HSR systems demonstrate higher efficiency compared to those in Europe; while China's HSR efficiency ranks medium in the HSR multi-stages chain but higher in the service stage. Furthermore, the determinants of organizational structure can significantly effect on the effectiveness of HSR systems under a certain transport density threshold. In conclusion, regulators and operators should endeavor to increase traffic by meeting the demand to improve system efficiency. For China, focusing on vertical integration should be the key aspect of future HSR reform.

高速铁路效率基准及其决定因素：对中国的借鉴

高速铁路（HSR）的性能引起了国际学者和政策制定者的极大关注。一个热门话题是衡量高铁效率及其重要决定因素，特别是高铁组织结构。我们研究的主要贡献是采用了多阶段网络数据包络分析（DEA）和Tobit模型，为解决这一问题提供了一种合理而连贯的方法。我们选择了2009-2018年期间主要高铁国家的数据集，并对不同国家的高铁效率进行了排名。随后，我们研究了高铁效率与特征决定因素之间的关系，以及可能影响该模型的地理和经济指标。研究结果表明，高铁生产率在各国之间确实存在差异。总体而言，与欧洲相比，亚洲的高铁系统表现出更高的效率；而中国的高铁效率在高铁多阶段链中排名中等，但在服务阶段排名较高。此外，在一定的运输密度阈值下，组织结构的决定因素会对高铁系统的有效性产生显著影响。总之，监管机构和运营商应该努力通过满足提高系统效率的需求来增加流量。对中国来说，关注垂直一体化应该是未来高铁改革的关键。
