Résumé
The purpose of this paper is to capture the direct and indirect effects of COVID-19 emerging risks on construction projects' success in developing countries from the contractors' perspective. To achieve this, we collected data from Iraqi construction industry and conducted the following multistage research methodology: (1) preliminary investigation with four construction contractors to identify the success indicators of construction projects;(2) focus group session with 11 experts to identify the COVID-19 emerging risks for the construction industry;(3) semistructured interviews with seven construction experts to develop several hypotheses on the effect of COVID-19 emerging risks on project success;(4) survey data collection from 99 construction contractors;and (5) development of a structural equation model (SEM) to analyze the effects of COVID-19 emerging risks on project success. The results of the SEM analysis show that financial market (FM)-related risks, supply chain operations (SCO)-related risks, health and safety of construction workforce (HSCW)-related risks, organizational implications (OI)-related risks, and contractual implications (CI)-related risks have a significant impact on construction projects success. CI-related risks have the strongest total effects on project success, followed by OI-related risks, FM-related risks, HSCW-related risks, and SCO-related risks, respectively. The results also emphasis the significant mediation role of CI between COVID-19 emerging risks and project success. This study contributes to the body of knowledge and contracting companies by helping researchers and construction contractors to better understand how the key risk factors emerging from extreme conditions like the COVID-19 pandemic affect construction projects' success and may serve as a guideline for developing effective response strategies. © 2023 American Society of Civil Engineers.
Résumé
Green finance (GF) supports the global fight against climate change and its impacts. It is critical to attaining the Paris Agreement and the United Nations Sustainable Development Goals. Since GF is regarded as the future of finance and investment, it needs to be fully understood. This paper presents the first mixed-methods systematic review with both bibliometric and qualitative analysis of the state-of-the-art and trends in GF research. A bibliometric review was performed to quantitatively examine 995 related publications retrieved from Scopus and validated with the Web of Science, Google Scholar, and ScienceDirect. Results showed that GF is still relatively an immature but interdisciplinary research area. A further qualitative-systematic analysis of 60 selected publications was conducted to identify the key findings, challenges, and recommendations for future research. Findings revealed six major research hotspots in GF: (i) green bond market and greenium, (ii) green credit (loan), (iii) carbon investment and market, (iv) green banking, (v) market stress (e.g. the COVID-19 pandemic) and GF, and (vi) domestic and international climate finance policies. This study provides insights into key applications of GF as it applies to specific research fields, a and as the pathways to realize the accruable benefits of GF to enhance research and development. © 2022 Informa UK Limited, trading as Taylor & Francis Group.
