英文摘要:
This paper examines three independent explanatory variables and their relation with cost overrun in order to decide whether this is different for Dutch infrastructure projects compared to worldwide findings. The three independent variables are project type (road, rail, and fixed link projects), project size (measured in terms of estimated costs) and the length of the project implementation phase. For Dutch projects, average cost overrun is 10.6% for rail, 18.6% for roads and 21.7% for fixed links. For project size, small Dutch projects have the largest average percentage cost overruns but in terms of total overrun, large projects have a larger share. The length of the implementation phase and especially the length of the pre-construction phase are important determinants of cost overruns in the Netherlands. With each additional year of pre-construction, percentage cost overrun increases by five percentage points. In contrast, the length of the construction phase has hardly any influence on cost overruns. This is an important contribution to current knowledge about cost overruns, because the period in which projects are most prone to cost overruns is narrowed down considerably, at least in the Netherlands. This means that period can be focused on to determine the causes and cures of overruns.

中文摘要:
本文研究了三个独立的解释变量及其与成本超支的关系,以确定荷兰基础设施项目的成本超支与世界范围内的调查结果是否不同。这三个自变量是项目类型(公路、铁路和固定连接项目)、项目规模(以估计成本衡量)和项目实施阶段的长度。就荷兰项目而言,铁路、公路和固定线路的平均成本超支分别为10.6%、18.6%和21.7%。就项目规模而言,荷兰小型项目的平均成本超支百分比最大,但就总超支而言,大型项目所占比例更大。在荷兰,实施阶段的长度,尤其是施工前阶段的长度是成本超支的重要决定因素。施工前每增加一年,成本超支百分比就会增加五个百分点。相比之下,施工阶段的长度对成本超支几乎没有任何影响。这是对当前成本超支知识的一个重要贡献,因为项目最容易发生成本超支的时期已经大大缩短,至少在荷兰是如此。这意味着可以集中精力确定超支的原因和治疗方法。
