Dynamic Role of Institutional Quality on Growth Impact of Capital Inflow, Finance, And Infrastructure Progress: Developing Country Perspectives

Based on the global dataset from 95 developing countries, this study examined the impact of capital inflow, finance, and infrastructure development on economic growth and also investigated the moderating role of institutional quality on economic growth.To address the research objective, the study adopted the Generalized Method of Moments (GMM) which theoretically maintains the endogeneity issue.Since the institutional quality varies across countries, the study also applied Quantile Regression to explore the effect of different level-capital inflow, finance, and infrastructure development prevailing across the selected countries on the economic growth.The finding clearly supported that capital, finance, and infrastructure development were very important for economic growth, whilst institutional qualities had a statistically significant moderating effect in our test models.Finally, the study carries a substantial momentum for the policy-making decision across developing countries.These findings emphasized the need for policymakers to strengthen institutional frameworks to enhance the effectiveness of infrastructure and financial investments.Consequently, developing countries can better leverage these factors for sustainable economic growth.
