In the first three quarters of this year，influenced by the changes in internal and external market environment，China’s fixed assets investment grows by 5.4%，the slowest growth rate in recent decades. However，the high-tech industry investment conducive to structural transformation and upgrading grows rapidly，the real estate investment also witnesses a relatively fast growth，and the investment and financing system reform has been deepened continuously. Due to the factors that private sector investment will be influenced by market expectations，the government and SOEs investment face the constraint of the leverage ratio and the space for regulating real estate investment will also be limited，the fixed assets investment in the fourth quarter will continue to be under downward pressure. Therefore，in order to stabilize the investment performance，employment and macro-economic growth，policy measures should be adopted to improve the general business environment，encourage private sector investment in social welfare projects，revitalize public sector stock assets，enhance the financing conditions for SMEs，and properly regulate the interest rate downward of the banking market.
