Risk in sustainable construction supply chains: construct development and measurement validation

Although previous studies have focused on different aspects of green/sustainability risk in construction supply chains (SCs) such as identification of risks or the linkage between characteristics of stakeholders and risk assessment, research on this topic is still quite limited. One important reason for this limitation is the absence of valid and reliable measurement of risk, resulting in the impossibility to discriminate between risk constructs. Therefore, the current study is performed to develop and then validate a measurement scale of risk in sustainable construction SCs. The data are collected from a large-scale survey supported by the Japanese government to promote sustainable socioeconomic development for the ASEAN (Association of Southeast Asian Nations) region, with the participation of 283 firms in Vietnam. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) are used to test the reliability, convergent validity, and discriminant validity of the risk constructs. The results indicate that all tests strongly support the measurement scale, and seven reliable risk constructs are identified including supply, demand, internal processes, information, financial, time, and environmental risks. This study also presents opportunities for further developing research on risk management (especially the three phases: risk assessment, risk mitigation, and risk monitoring) in sustainable construction SCs.
