Measuring the effect of deregulation to the regional inequalities

本文的主要研究成果是关于铁路服务的结构分离政策，特别是纵向(即运营-基础设施)分离和水平(即客货服务)分离。我们的研究结果表明，由于水平分离假人有一个具有统计意义的负号，可以看出水平分离可以降低铁路的成本。垂直分隔的效果随铁路组织列车密度的不同而变化。当列车密度较低时，垂直间隔往往会降低成本，而当列车密度较高时，垂直间隔会增加成本。

The main result of our study is about structural separation policies of rail service, especially vertical(i. e. operation-infrastructure) separation and horizontal(i. e. passenger-freight service) separation. Our findings show that because the horizontal separation dummy has a negative sign with statistical significance, horizontal separation can be seen to reduce the cost of a railway. The effect of the vertical separation changes according to the train density of a railway organization. With lower train density, vertical separation tends to reduce cost, while with higher train density vertical separation increases cost.
