The role of the construction industry in economic growth has been widely discussed in the extant literature, but existing studies have not investigated the disaggregated impact of construction investments on the production and social sectors. This study examines the disaggregated effect of construction investments on the Saudi economy. The study uses a social accounting matrix of Saudi Arabia and constructs a dynamic computable general equilibrium model. The findings reveal that construction investments significantly boosted GDP and aggregate investments in the first two periods; however, the growth declined in the following three periods. This finding underlines the importance of long-term investments in the construction sector and calls for continuous monitoring and updating of the investment policy for sustainable development. This study also presents the disaggregated impact of investments on the value-added by each sector of the economy. The ranking of sectors exhibits that mining and quarry activities underwent a high increase in value-added, second to construction activities. Other economic activities also experienced growth in value-added and some of them changed their ranks within the five years.

建筑投资对沙特经济的分类影响：沙特阿拉伯的动态可计算一般均衡模型

现有文献已广泛讨论建筑业在经济增长中的作用，但现有研究尚未调查建筑投资对生产和社会部门的分类影响。本研究探讨了建筑投资对沙特经济的分类影响。该研究使用沙特阿拉伯的社会核算矩阵，构建了动态可计算一般均衡模型。调查结果显示，前两个时期建设投资显着拉动了GDP和总投资；然而，在接下来的三个时期，增速有所下降。这一发现强调了建筑行业长期投资的重要性，并呼吁持续监测和更新可持续发展的投资政策。这项研究还介绍了投资对每个经济部门增加值的分类影响。行业排名显示，采矿和采石活动的附加值大幅增长，仅次于建筑活动。其他经济活动增加值也有所增长，其中一些经济活动在五年内发生了排名变化。
