Compared with the total amount and growth rate of fixed assets investment in the whole country, Jiangsu Province is in a leading position, but there still exist some problems in the declining growth rate of fixed assets investment, the structural imbalance of investors, the concentration of industry composition, the decline of investment growth rate in service industry and high-tech industry, and the irrational investment structure. The practical difficulties of optimizing the investment structure of Jiangsu province include: infrastructure investment is facing low return on investment and financing difficulties, which may further reduce the investment growth rate; the manufacturing industry of foreign-funded enterprises has intensified the return, which makes Jiangsu less attractive to foreign investment; the investment growth momentum of manufacturing industry is gradually losing, with the investment structure facing transformation; the supply and demand pattern of real estate changes, with the investment growth rate slowing down. Therefore, we suggest that Jiangsu should firstly, strengthen the regulation and management of government investment on the basis of market orientation; secondly, grasp the correct guidance and increase the efforts to attract foreign investment; thirdly, appropriately reduce the admittance threshold of service industry investment to give full play to market power to optimize the investment structure; fourthly, deepen the reform of investment and financing system, meanwhile exerting the advantages of state-owned capital; fifthly, encourage the innovation of financing mode and improve the ability of private investment.
