Abstract: Foreign direct investment（FDI） inflows play a crucial role in the economic growth of any country. FDI inflows in the economic literature and their impact on economic growth are worthy of attention. In order to analyze the main determinants of FDI inflows from Asian countries with high investment value in Laos, static and dynamic gravitational models were analyzed for relevant data from 1995 to 2015. The results show that natural resources （hydropower, mining）, last year's FDI, market size（host country）, inflation rate, infrastructure and WTO have a positive impact on Asian economies' FDI inflows into Laos; while real exchange rates and trade openness, relations with ASEAN, distance and economic crisis are not the key determinants of direct investment by Asian countries.

Key words: FDI, gravity model, Asian economies, Laos
