It has been controversial among economists about the impacts of globalization on growth, and the debate over the issue has intensified in recent years. In this study, we employ reliable panel data and an empirical growth model derived from production theory to investigate the effects of globalization on economic growth. The estimation results strongly suggest that economic globalization has a significant positive effect on economic growth for all countries. However, China and India would gain the most, followed by developed countries, and other developing countries would gain the least. Other important determinants of economic growth include capital, human capital, and technology.
