Fixed assets investment is an important engine to stimulate economic growth. In 2019，Jiayuguan’s fixed assets investment will pick up and improve，the industrial structure will be adjusted in depth，the infrastructure will develop steadily，the private investment and real estate development investment will be narrowed，and the reform of investment and financing system will continue to deepen. However，we need to pay attention to such problems as unreasonable investment structure，low proportion of private investment，saturation of investment in shed reform and real estate，further weakening of financial support capacity and insufficient investment stamina. It is suggested to continue to promote coordinated development of the three industries，accelerate the development of ten green ecological industries，strengthen the implementation of short-term，vigorously promote the construction of civil military integration industry，and make full efforts to promote it，promote the development of new infrastructure，plan and reserve major projects with high quality，maintain the healthy and sustainable development of private investment，further optimize the investment environment，and ensure the stable growth of investment in fixed assets.
