As an important part of China's current social and economic development, government investment projects involve all aspects of economy, environment, culture and life. Their work progress and implementation are directly related to the quality and speed of national economic development, the change of people's quality of life and the construction of a harmonious and peaceful society. How to strengthen the management of government investment projects, ensure the project quality and improve the investment benefit has become a hot spot and focus issue that people pay attention to and the government attaches importance to, which deserves our serious study. 1. Strengthening the management of government investment projects is the requirement of building a conservation-oriented society. Building a conservation-oriented society is China's basic national policy, and it is also an inevitable requirement for the full implementation of Scientific Outlook on Development. Strengthening the management of government investment projects, plugging the loopholes in capital construction expenditure, reasonably controlling investment costs and improving the efficiency of the use of financial funds are important aspects of promoting the construction of a conservation-oriented society, which is related to the overall economic and social development and has very important practical significance. It can not only strengthen government functions and improve government execution, but also meet the basic requirements of modern management benefit principle, which is conducive to overall consideration of social and environmental benefits, promoting resource conservation, reasonably reducing financial expenditure, and using limited financial funds to the cutting edge to better meet the needs of social and economic development. It is an important guarantee for building a well-off society in an all-round way and an important propeller for building a conservation-oriented society. 2. Strengthening the management of government investment projects is the requirement of establishing public finance, which has four functions: resource allocation, income distribution, economic adjustment and supervision and management. As an economic activity, government investment is not only a macro-control function of the government, but also a resource allocation problem, which is an important content of public finance management. By strengthening the management of government investment projects, we can not only eliminate all kinds of obstacles in market allocation of resources, promote the orderly flow of production factors, and solve the problems of public welfare and public infrastructure construction that cannot be effectively allocated by the market, but also promote the sunshine of public finance to tilt towards public utilities such as people's livelihood projects, "three rural" construction, environmental protection, and ensure the rationality of financial investment; It is also conducive to curbing the interception and misappropriation of construction funds, overestimation and "three excesses" waste, and improving the safety, compliance and economy of the use of financial funds; We can also urge the government to act cautiously in investment decision-making, improve the democratic decision-making mechanism of financial allocation, and improve the scientific rationality and transparency of financial budget arrangements. It can be said that strengthening the management of government investment projects is an important means to rationally allocate financial resources and supervise management functions according to law, an important part of financial work and an important means to promote the construction of public finance. 3. Strengthening the management of government investment projects is the requirement of building a clean government. Corruption is the number one cancer in China society. Preventing and punishing corruption from the source and vigorously advocating the construction of a clean government are important guarantees for promoting the construction of Socialism with Chinese characteristics, which is related to the future and destiny of the party and the country. China, the home page of China, is the weak link of corruption. Duty crimes in the construction field account for more than 90% of all duty crimes. If the project collapses, you will get kickbacks. Collusion in bidding and black-box operation; Illegal subcontracting, soliciting and accepting bribes; Commercial bribery, such as trading power and money and raising costs, violates laws and regulations, and the phenomenon of "the project goes up and the cadres fall down" is widespread, which seriously undermines the fair competition order of the market economy, affects the development environment of the national economy, corrupts the party style and people's customs, damages the image of the party and the government, and causes the loss and waste of state-owned assets. The masses reacted strongly to this. Government investment in construction has become the focus of anti-corruption, and effective measures must be taken to rectify it. Strengthening the management of government investment projects, standardizing government investment behavior and improving the effectiveness of government investment project supervision are conducive to creating a fair and just market competition environment, standardizing the operation order of socialist market economy, preventing the occurrence of corruption such as commercial bribery, improving the image of the party and the government among the people, and promoting the harmonious, stable, sound and rapid development of various socialist undertakings. 4. Strengthening the management of government investment projects is the need to improve the government's execution. "Management is a practice, and its essence lies not in knowledge, but in action." Executive power is the vitality of government work and an indispensable element for the government to fulfill its project management responsibilities. If the execution is weak, the government decrees are not smooth, some orders are difficult to execute, and even some command lines are impassable, the implementation of policies may be "much cry and little rain". Judging from the current situation of government investment project management in China. Many government investment projects are in disorder. The four functions of "investment, construction, management and use" are unified, with unclear division of labor and overlapping functions. The relevant departments are fragmented, and the offside and absence of management coexist and wrangle with each other. Low efficiency, weak project implementation, lax supervision, many loopholes and weak project cost control. It is often to pay the tuition fee for a project, which wastes a lot of manpower, material resources and financial resources. Strengthening the management of government investment projects, rationalizing the relationship between the relevant departments of government investment project management, establishing a government investment project management system with clear responsibilities, smooth communication and close cooperation, reducing buck passing, improving government execution, preventing management vacuum, and earnestly fulfilling the main functions of government investment project management have become hot and focus issues before us. 5. Strengthening the management of government investment projects is the need to improve the efficiency of government investment. At present, the investment plans of many government investment projects are made at will, lacking scientific argumentation. Before the project was approved, there were many "image projects" and "gift projects". In addition, the allocation and use of funds are free, and there is no pressure to maintain and increase the value and repay the principal and interest. In the implementation of the project, there is often a lack of effective external management and restraint measures to expand the construction scale, improve the construction standards and increase the construction content, and the budget constraints are weakened. Many projects are over-estimated, over-estimated and over-budgeted in the final accounts, and the investment is difficult to control, and the construction period has been postponed repeatedly. "Fishing project" and "beard project" are common, which not only affect the investment benefit, waste the national financial resources and public resources, but also hinder the development of social undertakings and easily breed corruption. Some also owe wages and project funds to migrant workers due to inadequate construction funds, which affects social stability and damages the image of government investment projects in the public. Strengthening the management of government investment projects, through purposeful planning, organization, command and regulation, will help standardize government investment behavior, speed up project progress, reduce financial expenditure, improve government investment efficiency, and create and form new productive forces.
