And also I found that RTP is themainly factor of contribute to economic growth and manpower had a rate of 20％to it. Then Iestimated the long-term and short-term effects of investment and economic growth by adoptingthe co-integration and Error Correction Model and found that there was a long equilibriumbetween investment and economic growth and if it disobeyed the equilibrium the ECM will havea little adjustment. Then I discussed the main deciding factors of investment and the growth ofGDP by using the simultaneous equations models and found that consumption is the key factorto stimulating investment and economic growth.
