This article is devoted to identifying and explaining the critical variables contributing to competitive advantages in international High-Speed Railway (HSR) projects from the contractor’s perspective. A total of 24 variables were identified by the literature review and a pilot study. An international questionnaire survey was performed to obtain professional opinions from both practitioners and the academy. The 24 variables were ranked and clustered into 6 factors using exploratory factor analysis. Furthermore, a case study of the Early Train Operator project of the California HSR was carried out by the survey, interview, and first-hand data. The results indicated that the top six ranked variables are (1) None Accident History, (2) Eligibility & International Criteria, (3) Contract Reputation, (4) Marketing Strategy, (5) Risk Management Capability, and (6) Technical Responsiveness. Furthermore, the 24 variables are grouped into six dimensions: Glocalization, Marketing, Safety, Economics, Technology, and Responsibility. The case study indicated that the factor framework was suitable and tractable for the application. The findings of this paper could (1) assist international HSR contractors in obtaining a better understanding of the deeper determinates of competitive advantages and (2) serve as a valuable reference for developing their competitive advantages in the international HSR market.

Investigating Political Risk Paths in International High-Speed Railway Projects: The Case of Chinese International Contractors

2019

Contracting in international high-speed railway (HSR) projects is a risky business. The success of these projects and the sustainable development of international contractors are inseparable from effective risk management. However, limited research has been conducted to investigate the political risk involved in international HSR projects. As HSR development is becoming a more major part of the global construction market, this paper investigates the political risk factors specific to the projects and the relationships among the factors. Through a literature review and a pilot interview conducted with five Chinese professionals, 26 political risk factors were proposed. A questionnaire was then administered to 112 experts from both academia and industry to assess the significance of the factors. By applying partial least-squares structural equation modeling (PLS-SEM) technology, the 26 factors were clustered into eight groups, and 10 significant risk paths were identified. Specifically, “government attitudes” can directly influence the “investment profile” and “social support” can directly influence “government attitudes,” while “government instability,” “economic climate,” “financing and costs,” “external interference,” and “contractors’ operations” can indirectly influence investment profile by directly influencing “government attitudes” or “social support.” The findings of this study can assist international contractors with gaining a clear understanding of the political risk involved in international HSR projects, which will lead to more effective political risk management as well as better business decisions. Furthermore, this paper will contribute to the global body of knowledge in the area of political risk management for large-scale international projects.

“…A column supported embankment (Ali et al, 2012;Okyay et al, 2014;Basack et al, 2015;Bian et al, 2016;Liu and Rowe, 2016;Liyanapathirana and Ekanayake, 2016;Briançon and Simon, 2017;Das and Deb, 2017a;Jelušič and Žlender, 2018) is commonly used when freeways or railways pass through soft soil areas, or to support storage tanks and bridge abutments (Naggar et al, 2015). This technique can reduce settlement (Tan et al, 2008;Yapage and Liyanapathirana, 2014;Yapage et al, 2015;Chen et al, 2016a;Das and Deb, 2017b;King et al, 2017) and accelerate the construction process (Briançon and Simon, 2012;Fagundes et al, 2017;Nguyen et al, 2017). However, the most significant drawback of this approach is the possible localized differential settlement at the surface of the embankment, caused by the difference between the modulus of the columns and that of the subsoil (Taha et al, 2014;Tai et al, 2018).…”
