The interrelations between the regional economic growth and savings are analyzed by using Johansen cointegration test and Granger causality test based on error correction model. The results show that the economic growing is one of the main factors that raise the amount of saving but don't increase the saving growth rate in all three regions. Also the increase of saving could result in the eastern and weatern region's economic growth to some extent, but it does't affect the central region's economic growth. Therefore, some actions which drive the economic growth have to be taken in order to raise the saving, and the increase of the saving scale have to be controled to improve the regional economic growth.
