In recent years，the global economy has shown a short-term stagnation in economic growth，the deflation pressure has been increased，the marginal effect of policy stimulus has been weakened，the substantial economy has run sluggish，and moreover，the uncertainty of economic recovery has increased the typical characteristics. The economy in China is also facing the problem of “four drops and one raise”. On the way to economic recovery，China’s economy has a strong logical consistency with the world economic growth. In the long term，using the structural reform to solve the crisis is the key，and to seek new growth opportunity at the same time. Within the short term，the motive force of economic growth is to encourage investment，only steady investment helps the steady growth. It has been estimated that the total investment in whole society’s fixed assets investment in 2018 will be increased about 9 percent，which shows a slight increase compare to 2016. At present，steady investment needs to focus on breakthroughs：firstly，to balance the infrastructure investment，real estate investment and manufacturing investment within the investment structure and to enhance the sustainability of investment；secondly，while maintaining the proper growth of the state-owned investment，to encourage the motive force of private investment through system installation in order to stimulate private investment which also help to avoid a new round of “guojinmingtui”（the state advances，the private sector retreats）；thirdly，to alert the extensive mode of investment growth，to improve investment efficiency，to optimize the investment structure and to expand the effect demand.
