During the 15th Five Year Plan period, we must fully leverage the key role of investment, actively expand investment space, adhere to the close combination of investment in goods and investment in people, vigorously boost consumption, and expand effective investment. At the same time, by focusing on improving investment efficiency, adjusting and optimizing investment structure, implementing a number of major landmark engineering projects, and releasing effective investment demand. The Fourth Plenary Session of the 20th Central Committee of the Communist Party of China put forward the major task of "building a strong domestic market and accelerating the construction of a new development pattern", and put forward requirements and directions for expanding effective investment during the "15th Five Year Plan" period. Fully leverage the key role of investment. In the short term, investment can quickly mobilize resources, release multiplier effects, and stabilize the overall economy. In the long run, investment promotes the formation of a higher-level dynamic balance where demand drives supply and supply creates demand by optimizing industrial structure and improving production efficiency. During the 14th Five Year Plan period, the annual average contribution rate of total capital formation to economic growth exceeded 30%. Practice has proved that investment has always been a key force in coping with risks and challenges, promoting high-quality development, and ensuring the stability of Chinese path to modernization. Actively expanding investment space. During the 15th Five Year Plan period, we must adhere to the close combination of investing in goods and investing in people, vigorously boost consumption, and expand effective investment. There are still many shortcomings in China's infrastructure sector. Urban renewal and underground pipeline renovation will generate huge investment needs, and investment in public services such as healthcare needs to be further increased. Key core technology areas need to continuously increase investment to fill the gaps, and green and low-carbon transformation in areas such as construction and transportation will also generate new investment opportunities. Focus on improving investment efficiency. More emphasis should be placed on maximizing economic benefits, and investments should be able to form effective assets, generate reasonable returns, and promote industrial upgrading; More emphasis should be placed on leveraging social benefits, and investments should be able to improve people's livelihoods, promote employment, and enhance the level of public services; Pay more attention to ecological benefits, invest in green development requirements, and promote harmonious coexistence between humans and nature; More emphasis should be placed on ensuring safety and efficiency, investment should comply with the overall national security concept requirements, and achieve a dynamic balance between development and security. Adjust and optimize the investment structure. The investment structure in the new era should resonate with the requirements of the times. During the 15th Five Year Plan period, investment structure should pay more attention to "investing heavily, investing in the public, expanding scenarios, and cultivating new qualities". One is to focus on major national strategies and invest in key areas such as addressing weaknesses, strengthening foundations, and fostering momentum; Secondly, we will adhere to the principle of people's livelihood and increase investment in education, healthcare, and "one elderly, one primary" sectors; The third is to expand emerging scenarios, focusing on digital economy, low altitude economy and other directions, strengthening investment in cutting-edge fields, and empowering thousands of industries with "artificial intelligence+"; The fourth is to cultivate new quality productive forces, promote the integrated development of scientific and technological innovation and industrial innovation, and enhance the international competitiveness of industries. Implement a batch of major landmark engineering projects. The construction and implementation of 102 major projects during the 14th Five Year Plan period played an important role in promoting economic growth, ensuring the improvement of people's livelihood, and consolidating the security foundation. During the 15th Five Year Plan period, landmark projects should be used to drive the implementation of national strategies, and a number of projects with global impact and national will should be implemented to accelerate the implementation of major national strategies and the construction of security capabilities in key areas. Implement a number of major projects in areas such as infrastructure, basic scientific research, public health, ecological protection, urban renewal, and rural construction to unleash effective investment demand. Comprehensively deepening the reform of the investment system is an important part of improving the socialist market economy system. During the 15th Five Year Plan period, we need to increase the value of streamlining administration and delegating power, accelerate the relaxation of private investment access, systematically promote the reduction of approval, the addition of services, the multiplication of efficiency, and the division of risks, and support private enterprises to invest in emerging and future industries. At the same time, we will improve the mechanism for stimulating social capital investment vitality and promoting investment landing, continue to play a guiding and leveraging role of new policy based financial instruments, build a scientific and efficient government investment fund management system, encourage and regulate the development of market-oriented financing methods such as angel investment and venture capital, and effectively stimulate the investment vitality of the whole society.
