Abstract
Research on aid effectiveness has focused on the relationship between aid effectiveness and the governance of developing countries. However, no research shows the relationship between the effectiveness of Japanese ODA projects and governance measured by quantitative analysis. This study aims to clarify the influence of governance in developing countries on the effectiveness of JICA technical cooperation projects and on the sustainability of their effects. 181 projects intended to assist developing countries between 1998 and 2007 were examined. From regression analysis, it was found that the governance measured by Worldwide Governance Indicators did not have any significant explanatory power on project effectiveness, but was significantly related to the sustainability of project effects. The influence of the developing country's governance, economics and education on the effects of the project was also examined by covariance structure analysis. The study showed that governance, economics and education did not affect project effectiveness, but did promote the sustainability of project effects. It was also discosverd that governance indirectly influenced the sustainability of project effects through economics or education.
