Abstract

This study assessed the moderating influence of governance quality on the effect of health expenditure on economic growth, and exploring the analysis further to determine whether there exists possible heterogeneity in the distribution of this effect amongst 27 Sub‐Saharan African countries for the period 2005–2021. Public health expenditure (HExp), and six indicators of governance quality (control of corruption [Ccor], rule of law [Rlaw], political stability [Post], voice and accountability [Vacc], government effectiveness [Geft], and regulatory quality [Regq]) were utilised as proxy(ies) for HExp, and governance respectively. Two‐step dynamic panel data system generalised method of moments (DPD‐SGMM) estimation technique was used to estimate the conditional mean effect, while Possible heterogeneity in the distribution was explored using the method of moments quantile regression (MM‐QR); the study relied on annual time‐series indices of governance as developed by Kaufman and Kraay. Estimates demonstrate that: (i) while a significant positive relationship was observed between HExp and economic growth, Rlaw, Vacc, and Regq significantly reduce economic growth, (ii) interaction between HExp, and Vacc, Regq, individually increases the potency of HExp to stimulate economic growth by 2.2%, and 1.2% respectively, as against 1.3% reduction for Rlaw, (iii) no heterogeneity was observed in the distribution of these amongst the sample of countries.

撒哈拉以南非洲国家的医疗支出与经济增长：治理质量的作用

本研究评估了治理质量对医疗支出对经济增长影响的调节作用，并进一步探索分析，以确定在 2005-2021 年期间，这一影响在 27 个撒哈拉以南非洲国家中的分布是否可能存在异质性。公共卫生支出（HExp）和六个治理质量指标（腐败控制[Ccor]、法治[Rlaw]、政治稳定[Post]、发言权和问责制[Vacc]、政府效率[Geft]和监管质量[Regq]）分别被用作 HExp 和治理的替代指标。采用两步动态面板数据系统广义矩量法（DPD-SGMM）估算技术估算条件均值效应，同时使用矩量回归法（MM-QR）探讨分布中可能存在的异质性；研究依赖于考夫曼和克拉伊开发的年度治理时间序列指数。估计结果表明(i) 虽然观察到 HExp 与经济增长之间存在显著的正相关关系，但 Rlaw、Vacc 和 Regq 则显著降低了经济增长，(ii) HExp 与 Vacc、Regq 之间的交互作用使 HExp 刺激经济增长的效力分别提高了 2.2%和 1.2%，而 Rlaw 则降低了 1.3%，(iii) 在样本国家中没有观察到这些指数分布的异质性。

期刊介绍： The Review of Development Economics is a leading journal publishing high-quality research in development economics. It publishes rigorous analytical papers, theoretical and empirical, which deal with contemporary growth problems of developing countries, including the transition economies. The Review not only serves as a link between theorists and practitioners, but also builds a bridge between development economists and their colleagues in related fields. While the level of the Review of Development Economics is academic, the materials presented are of value to policy makers and researchers, especially those in developing countries.
