This paper measured the significant factors leading to performance challenges across state-owned refineries in Nigeria based on experts’ views. The study was carried out with a view of making policy recommendations to help address these issues and thereby improve performance. A quantitative approach was adopted to sample the viewpoints of the professionals who work across the NNPC refineries. Using a Likert-type questionnaire, the professionals’ expert opinions were ranked across four main categories covering political, economic, social, and technical (PEST) factors. A Cronbach alpha test was performed to certify the consistency and reliability of the sub-category factors included on the Likert scale. In addition, a multivariate analysis of variance (MANOVA) was carried out to check for any statistically significant differences in the respondents’ opinions as a result of their different years of work experience. The study revealed that while all four PEST factors are crucial to the performance of the state-owned refineries in Nigeria, political, economic, and technical factors were viewed as more significant than the social factors. A comparative analysis of the sub-category factors using the relative significance index (RSI) and the respondents’ mean scores of importance (RMSI) revealed that government interference, funding issues, political indecision, theft and pipeline attacks, cost of spare parts, maintenance issues, operating capital, feedstock supply, staff training and competence issues are some of the significant factors that affect the performance of the refineries. The identified performance challenges from this study were used to inform policy recommendations to help address the problems of the refineries.

本文根据专家的观点，衡量了导致尼日利亚国有炼油厂绩效挑战的重要因素。进行这项研究的目的是提出政策建议，以帮助解决这些问题，从而提高绩效。采用定量方法对 NNPC 炼油厂工作的专业人员的观点进行抽样调查。使用李克特式调查问卷，专业人士的专家意见按四个主要类别进行排名，涵盖政治、经济、社会和技术 (PEST) 因素。进行 Cronbach α 检验以验证李克特量表中包含的子类别因素的一致性和可靠性。此外，还进行了多变量方差分析（MANOVA），以检查受访者的观点是否因工作经验的不同年份而存在统计上的显着差异。研究显示，虽然所有四个 PEST 因素对尼日利亚国有炼油厂的绩效都至关重要，但政治、经济和技术因素被认为比社会因素更重要。使用相对显着性指数（RSI）和受访者的重要性平均分（RMSI）对子类别因素进行比较分析表明，政府干预、资金问题、政治优柔寡断、盗窃和管道攻击、备件成本、维护问题、运营资本、原料供应、员工培训和能力问题是影响炼油厂绩效的一些重要因素。本研究确定的绩效挑战被用来提供政策建议，以帮助解决炼油厂的问题。
