The results show that: (1) There is a long-run cointegrated relationship between construction land expansion and economic growth, and the change of them have the homogeneity; (2) Economic growth is the Granger cause of construction land expansion, while construction land expansion is not the Granger cause of economic growth; (3) Construction land expansion makes a small contribution to economic growth, and with lag phase prolonged, the contribution rate becomes stable, and economic growth is significantly affected by its own rather than by construction land expansion; (4) The contribution rate of economic growth to construction land expansion reaches up to more than 90%, and economic growth is the dominant factor which drives the expansion of construction land.
