There is a definite link between foreign direct investment and economic growth. However, due to the differences of regional industrial structure, resource status and economic system, the foreign direct investment efficiency is also different. In this paper, we add the factor of foreign quality to the foreign investment and regional economic growth model during the empirical research. As a result, regional differences between the quality of foreign direct investment led to a difference in the rate of contribution to economic growth areas, that is to say，capital heterogeneity will directly affect the degree of FDI effects on economic growth in different regions and even the direction. It follows that, it is necessary to change the ideas in the process of attracting investment and eliminating the unbalances that FDI’s influence on the regional economic development, namely, from a simple shift emphasis on increasing the number of foreign capital to improving the quality of capital, increasing foreign investment in output efficiency.
