摘要

事实证明,建筑业的特点是服务提供效率低下和无效。本文的主要目标是研究影响埃塞俄比亚公共基础设施项目绩效的关键因果因素,以改善该行业的服务提供。基于对现有理论和调查分析整理的58个因素,我们为埃塞俄比亚建筑业专业人员编制并发放了700份结构化调查问卷;共收到578份,占82.57%。对收集到的数据进行扩展统计分析的结果显示,影响埃塞俄比亚政府资助的基础设施项目绩效的前8个关键具体因素包括:项目规划管理体系差,项目管理领导能力和机构能力弱,项目设计不完善,建筑材料价格上涨,各方缺乏一体化的项目规划体系,承包商能力不足,项目进度和成本管理体系差。本研究对建筑行业从业人员、政府官员和研究人员具有一定的启示意义。通过促进基础设施投资,创造就业机会,并通过其复杂的价值链成为另一个商业部门的中间产品和相关服务的主要消费者;建筑业是一个国家社会经济发展的引擎[1,2][3-5]。然而,该行业受到许多内部和外部因素的困扰,这些因素阻碍了全球该行业的生产力。其中的关键问题包括:行业性质复杂、监管不断变化、承包商不可靠、保险成本高、技术采用限制、管理方面、市场价格变化、资金和技术能力不足、劳动力短缺、生产率水平停滞不前以及未能按预期时间、成本和质量标准交付项目是该行业最受约束的问题[6]。因此,当今建设项目在全球范围内的特点是低效和无效的项目交付[7-11]。由于存在各种影响行业生产率的潜在问题,该行业表现不佳[12-13]。以往的研究阐明了影响建筑业绩效的各种因素。然而,由于这个世界的一切都在迅速变化,要彻底了解这个行业表现不佳所导致的潜在问题,还有很大的差距[5,14]。在与建筑业业绩有关的问题方面,埃塞俄比亚也不例外。在埃塞俄比亚的案例中,项目参与者之间的冲突、项目经理的无知和缺乏知识以及人力资源管理不善是阻碍公共项目进度绩效的首要因素[15]。也有人认为,由于不重视规划、未能及时更新进度、合同管理不善、现场监督不力、建筑材料价格上涨、更改订单、延迟付款、进度超支、质量缺陷成本超支、能力问题、组织和协调不力,埃塞俄比亚公共基础设施项目执行失败导致绩效失败[16,17]。从全球角度到当地(埃塞俄比亚的案例),这些长期问题背后的神秘之处使我对高等教育、管理与人文国际会议(AEMH 2019)充满热情。亚特兰蒂斯出版社出版。这是一篇基于CC BY-NC许可(http://creativecommons.org/licenses/by-nc/4.0/)的开放获取文章。社会科学、教育和人文研究进展,第352卷

A Study on Critical Factors Affecting Public Infrastructures Project Performance in Ethiopia
It has been demonstrated that the construction industry can be characterized by inefficient and ineffective service delivery. The main goal of this paper is to examine the critical causal factors affecting public infrastructures projects performance in Ethiopia in order to improve the industry’s service delivery. Based on the 58 factors compiled through the analysis of existing theories and investigations, we prepared and distributed 700 structured survey questionnaires for professionals in the construction industry of Ethiopia; and received 578 (82.57 %) of them. The results from an extended statistical analysis on the collected data revealed that the top 8 critical specific factors affecting government-financed infrastructures projects performance in the Ethiopia comprehends: poor project planning & administration system, weak project management leadership skills & institutional capacity, inadequate project design, escalation of construction materials price, lack of integrated project planning system among parties, inadequate capacity of the contractor, poor project schedule and cost management system. The study has an implication for construction industry practitioners, government officials, and research fellows. Introduction Through promoting infrastructures investments, create job opportunities, and deeds as a major consumer of intermediate products, and related services from another business sector via its complex value chain; Construction Industry acts as an engine for socio-economic development of a nation[1, 2] [3-5]. However, the sector is troubled with numerous internal and external factors that hamper the productivity of the industry across the world. The critical of them include: its complex nature, ever regulation change ,unreliable contractor, high insurance cost, technology adoption limitation, management aspect, market price change, inadequate capacity both in finance and technique, labor shortages, stagnant productivity level and failing to delivery project as the intended time, cost and quality standards are belongs to the most constraints of this sector [6]. Consequently, nowadays, a construction project is characterized by inefficient and ineffective project delivery globally[7-11]. Due to the presence of varied underlying problems which affect industry productivity, the sector is characterized by underperformance [12-13]. Previous studies clarified diverse factors affecting the performance of the construction industry. Though, due to the rapid changes in everything in this world, there is still a wide gap to thoroughly understand the underlying problems caused by the underperformance of this sector [5, 14]. Ethiopia has no exception regarding problems associated with the construction industry performance.
