摘要

我们利用 DEA 分析比较了西欧和东欧铁路的效率,发现西欧的大多数铁路都处于效率前沿,而东欧的铁路通常离效率前沿很远。其中一个原因可能是东欧的改革进程起步比西方晚得多,尽管东欧似乎在很大程度上已经迎头赶上。其次,共产主义政权结束后,东欧遭受了巨大的交通损失,这可能仍然导致劳动力和资产过剩。有证据表明,劳动力和货运车辆仍然过剩。尽管过剩的货运车辆可能主要是停用的车辆,但它们仍然导致东欧的效率得分较低。此外,东欧国家在人口密度方面也存在一些劣势。不过,我们认为,与西方国家相比,东欧国家的表现较差,有两个方面的政策起了重要作用。首先,与投资水平较低有关的基础设施质量较差。这表现为电力牵引使用较少,列车速度较慢,导致员工和资产的生产率较低。尽管欧盟委员会努力克服这一问题,但仍有很长的路要走。其次是大力履行公共服务义务,以相对较低的负载率维持高水平的服务。如果希望提高东欧铁路的效率,东欧各国政府就需要考虑它们是否规定了过高的服务水平。

Why are the railways of Eastern Europe less efficient than those of the West?

We use a DEA analysis to compare the efficiency of the railways of Western and Eastern Europe and find while most railways of Western Europe are on the efficiency frontier, those of Eastern Europe are typically a long way from it. One explanation may be that the reform process only started much later in Eastern Europe than in the West, although it appears that Eastern Europe has largely caught up. Secondly, Eastern Europe suffered a significant loss of traffic after the end of the communist regime, and this may still be resulting in an excess of labour and assets. There is some evidence that this remains the case for labour and freight vehicles. Although the excess of freight vehicles may be largely vehicles out of service, they still contribute to the poor efficiency scores for Eastern Europe. It is also the case that the countries of Eastern Europe suffer some disadvantages in terms of population density. However, we believe that two aspects of policy play an important role in the poorer performance of Eastern European countries compared with Western. Firstly, is the poorer infrastructure quality associated with lower levels of investment. This shows up as less use of electric traction and slower train speeds, resulting in lower productivity of staff and assets. Despite the efforts of the European Commission to overcome this problem, there is still a long way to go. Secondly, is the strong use of public service obligations to maintain high levels of service with relatively low load factors. If it is desired to raise the efficiency of Eastern European railways, governments in Eastern Europe will need to consider whether they are specifying excessively high levels of service.
