Unlike existing studies only emphasize the causes and impacts of land finance respectively from fiscal decentralization and economic performance, based on the firstgeneration panel and secondgeneration panel unit root test, this paper analyzes the expansion and impacts of land finance, using 1998—2012 provincial panel data and pooled OLS, FE OLS, SYSGMM.The results show: firstly, land finance not only affected by the homogeneity of the central taxation system, but also by heterogeneity of local noninstitutional factors, like as human capital, population size, industrial structure and technological development; secondly, land finance is not exist “absolute grab”, it is essentially “nominal grab” and has some benefits in shortterm. This paper finds that land finance is misunderstood in causes and consequences. In postera of land finance, we must change the perspective of income from “sell for money” to “make money by itself”, change the perspective of from “capital accumulation” to “credit financing”, change the business model from the “capital accumulation” to “land fund”, to resolve the slow growth of local governments finance and to make up payments gap for promoting new city.
