Globally, child mortality rates continue to be unacceptably high despite improvement in child health outcomes. The role of macro level indicators, such as governance and health aid on child mortality, remains under-researched. The aim of this article is to analyse the influence of governance and health aid on child mortality using cross-country data. A negative association between governance and the mortality rate of children less than 5 years of age was found using System Generalised Method of Moments Dynamic Panel, the linkage also exists in the results of quantile and semi-parametric regression. However, as in other literature, the role of health aid on child mortality remains ambiguous.
