Since 2018，international trade protectionism has risen，and the trend of anti-globalization has emerged；domestic reform has entered the deep-water areas，shifting from high-speed growth to high-quality development. Influenced by both internal and external factors，China’s investment situation has changed，the growth rate of total investment in fixed assets has slowed down，and continues to be lower than the GDP growth rate，the investment in different regions and sub-industries has been polarized，and the investment structure has entered a deep adjustment. Therefore，it is necessary to further promote the technological innovation and upgrading of manufacturing industry，establish a long-term regulation mechanism of real estate industry，and play the role of “making up the shortcomings” of infrastructure industry；further accelerate the pace of “mixed ownership reform” of state-owned enterprises，strengthen tax reduction and fee reduction efforts of private enterprises，and promote the complementary and win-win development of the two sectors；further optimize the structure of foreign investment，utilize the technology spillover effect of FDI，and work together to draw a new pattern of opening up. Promoting the structural reform of China’s investment supply side with greater courage and determination，provides an important guarantee for the stable and healthy development of China’s economy.
