Skilled labour shortage in construction industry is a major challenge in South Africa. Therefore, the objective of the study is to assess the factors that cause skilled labour shortage, its consequent effects on the construction industries and how the scenario can be improved. The study was conducted by considering construction industry in the Eastern Cape of South Africa and using a survey research method and conceptual System Dynamics (SD) modelling. Findings reveals that investment, wage challenges, talent management, work environment, training, experience, and Government policy are the important challenges for the skilled labour shortage. Inadequacy of skilled labour considerably impacts the quality of work, productivity, and scheduling. The causal loop diagrams show that enhancement in investment in the labour wages will strengthen the availability of skilled labourers leading to higher productivity, and vice versa. Talent management based on appropriate recruitment and retention policy, staff development programmes and investment in these aspects will augment the skilled labour pool. Also, a better work environment through a policy of health and safety, investment in working condition and supported by Government policy will reduce the attrition of the labourer because of job dissatisfaction, which consequently will reduce the skilled labour shortage in the industry.

缓解建筑行业技术工人短缺的系统动力学方法：南非

南非建筑业的技术工人短缺是一项重大挑战。因此，研究的目的是评估导致技术工人短缺的因素，其对建筑行业的影响以及如何改善这种情况。该研究是通过考虑南非东开普省的建筑业并使用调查研究方法和概念性系统动力学（SD）建模进行的。调查结果表明，投资，工资挑战，人才管理，工作环境，培训，经验和政府政策是技术工人短缺的重要挑战。技术工人的不足会严重影响工作质量，生产率和计划安排。因果关系图表明，增加对劳动工资的投资将增强熟练工人的可用性，从而导致更高的生产率，反之亦然。基于适当的招聘和保留政策，员工发展计划和在这些方面的投资的人才管理将增加熟练劳动力的数量。此外，通过健康和安全政策，对工作条件的投资以及政府政策的支持，更好的工作环境将减少由于工作不满意而导致的劳动力的流失，从而减少行业中熟练工人的短缺。员工发展计划和在这些方面的投资将增加熟练劳动力的数量。此外，通过健康和安全政策，对工作条件的投资以及政府政策的支持，更好的工作环境将减少由于工作不满意而导致的劳动力的流失，从而减少行业中熟练工人的短缺。员工发展计划和在这些方面的投资将增加熟练劳动力的数量。此外，通过健康和安全政策，对工作条件的投资以及政府政策的支持，更好的工作环境将减少由于工作不满意而导致的劳动力的流失，从而减少行业中熟练工人的短缺。
