The study purpose was to examine ethical procurement practices on cost-effectiveness in government organizations in south Sudan with specific focus on Ministry of Finance and Economic Planning. The specific objectives were guided by the theoretical frameworks of stakeholder theory and the Resource-Based View (RBV) of the firm as follows; to examine how stakeholder identification enhance cost effectiveness within the Ministry of Finance and Economic Planning, To evaluate how stakeholder engagement ensures cost effectiveness in the Ministry of Finance and Economic Planning and To assess how identifying internal resources and capabilities affect cost effectiveness in the Ministry of Finance and Economic Planning In this particular study, the research design was subdivided into research strategy, research approach, research duration and research classification. A study population of 200 employees comprised of key departments including budgeting and planning, revenue and taxation, financial management, economic policy, and procurement. The sample size for the study was 127 employees that was generated using Krejcie and Morgan Table (1970). Quantitative results, including descriptive statistics (means, standard deviations) and inferential statistics (correlation coefficients, regression coefficients), were displayed in tables using SPSS version 24. While qualitative findings were summarized thematically, highlighting key themes and illustrative quotes from interviews. The correlation analysis revealed a moderate positive relationship between stakeholder identification and cost-effectiveness, with a Pearson correlation coefficient of (r = 0.613) and a significance level of 0.001. The strong positive correlation (r = 0.640) between stakeholder engagement and cost-effectiveness, along with a statistically significant p-value of 0.000, shows the critical importance of stakeholder engagement in achieving higher cost-effectiveness. The correlation analysis demonstrated a positive relationship between internal resources capability and cost-effectiveness, with a Pearson correlation coefficient of 0.614 and a significance level of 0.000. This indicated that as the Ministry improves its internal resources and capabilities, cost effectiveness in procurement also improves. The regression model, which includes stakeholder identification, stakeholder engagement, and internal resources capability, explained 49.3% of the variance in cost-effectiveness (R² = 0.493). The model's statistical significance (F = 29.488, p < 0.000) indicated that these three factors collectively have a substantial and significant impact on cost-effectiveness in procurement practices. It was recommended that: the Ministry of Finance and Economic Planning should regularly review and update its stakeholder identification procedures, the Procurement Department should establish a formal process for gathering and acting on stakeholder feedback. The Ministry should focus on building and maintaining strong relationships with key stakeholders.
