Abstract

This paper aims to elucidate the phenomenon of cost overruns resulting from government-led risks, with a specific focus on contract changes within the context of 70 Indonesian toll road projects. The dataset demonstrates a broad spectrum of cost overrun rates (COR), from −34.43% to 356.54%, with a median of 0.00% (mean = 14.83%). Empirical evidence demonstrates that contract changes exert a discernible influence on cost overruns. Among the sampled projects, 39 out of 70 encountered changes in their original contracts, and within this subset of projects, the median COR was 7.00% (mean = 26.63%). In the case of projects experiencing cost overruns and underruns, the median COR amounted to 21.00% (mean = 44.55%, n = 27) and −13.50% (mean = −13.72%, n = 12), respectively. This paper delves into the correlations between the COR and various project attributes, providing elucidations grounded in the framework of multiple theories in the literature.

印度尼西亚收费公路因政府主导的风险而超支

本文旨在阐明由政府主导的风险导致的成本超支现象，特别关注印度尼西亚 70 个收费公路项目的合同变更。数据集显示了成本超支率 (COR) 的广泛范围，从 -34.43% 到 356.54%，中位数为 0.00%（平均值 = 14.83%）。经验证据表明，合同变更对成本超支有明显的影响。在抽样调查的 70 个项目中，有 39 个项目的原始合同发生了变更，在这部分项目中，COR 的中位数为 7.00%（平均值 = 26.63%）。在成本超支和成本不足的项目中，COR 中值分别为 21.00%（平均值 = 44.55%，n = 27）和 -13.50%（平均值 = -13.72%，n = 12）。本文深入探讨了 COR 与各种项目属性之间的相关性，并在文献的多种理论框架下进行了阐释。
