According to the law of diminishing marginal returns，capital should flow from rich countries to poor countries，which is inconsistent with the fact of FDI flowing to rich countries in very large scale. The important reason is that the rich countries have a high human capital stock，that is，the famous “Lucas Paradox”. Based on China inter-provincial panel data，this paper analyzes the FDI location decisions. The regression results show that，at the national level，the stock of human capital is correlated with FDI inflows negatively. However，at the regional level，the stock of human capital is correlated with FDI inflows positively，which，at certain extent，certifies the existence of “Lucas Paradox” in China different regions.
