Abstract: By reconstructing the absolute crowding in or out relationship between FDI and domestic investment, we correct the flaws of the existed relative crowding in or out model. Using larger sample of Panel data and comparing the different estimates from “absolute“ and “relative“ models, we find no significant crowding in or out effects in China from the country level. However, further study reveals that the crowding in or out effects show a fine regional characteristic:crowding out effects dominate in eastern China, crowding in effects lead in mid China, and crowding out effects are insignificant in west China.
