This paper analyzes the development status of real estate investment and economic growth in Anhui Province from 2010to 2019. Both of them maintain a stable and good growth in the past ten years, and have a strong positive correlation. This paper uses linear regression model to empirically test the data from 2010to 2019, and accurately calculates the promotion effect of real estate investment on economic growth. Every 100million yuan of real estate investment can increase the GDP of 53549 million yuan. In addition, combined with the current situation of Anhui's economic development, this paper explores the impact mechanism of real estate investment on economic growth. Although real estate investment has positive effects on promoting investment, promoting the development of related industries and providing employment,it also has obvious crowding out effect, real estate investment bubble inhibition and market risk.
