Although an active body of literature exists on the relationship between government size and corruption, different findings proliferate the literature due to the nuances of geographical context, methods, and variables employed. The paper employs the novel method of moment quantile regression with fixed effects over the period 1984–2018 to investigate the dynamic impact of government size and press freedom on corruption in Sub-Saharan African (SSA) countries. The main contribution is to examine the impact of government size and press freedom across the conditional distribution of corruption in SSA. The findings show that the impacts of government size and press freedom are heterogeneous across the conditional quantile distribution of corruption. Among the most corrupt countries in SSA, larger government size and press freedom significantly increase corruption. Some policy recommendations are offered based on these findings.

尽管关于政府规模与腐败之间关系的文献活跃，但是由于地理环境，方法和变量的细微差别，不同的发现使文献激增。本文采用新颖的矩分位数回归方法，在1984-2018年期间固定影响，以研究政府规模和新闻自由对撒哈拉以南非洲（SSA）国家腐败的动态影响。主要的贡献是研究在撒哈拉以南非洲有条件的腐败分布中，政府规模和新闻自由的影响。研究结果表明，在腐败的有条件分位数分布中，政府规模和新闻自由的影响是不同的。在撒哈拉以南地区最腐败的国家中，更大的政府规模和新闻自由大大增加了腐败。根据这些发现提供了一些政策建议。
