Bidding system is a management system established for the rational distribution of the rights, obligations and responsibilities of both tenderers and bidders. Strengthening the construction of bidding system is the requirement of market economy. The role of the bidding system is mainly reflected in the following four aspects [3]:
(1) Improve economic and social benefits through bidding.
The basic feature of China's socialist market economy is to give full play to the role of the competition mechanism, so that market players can compete fairly under equal conditions, and the survival of the fittest can be eliminated, thus realizing the optimal allocation of resources. Bidding is an important way of market competition, and its greatest advantage is that it can fully embody the principle of "openness, fairness and justice". Through bidding and purchasing, many bidders can compete fairly and get the best goods, projects or services at the lowest or lower price, thus improving economic and social benefits, improving the quality of bidding projects, improving the efficiency of the use of state-owned funds, and promoting the investment and financing management system and management system reform in various industries.
(2) Enhance the competitiveness of enterprises through bidding.
Promote enterprises to change their management mechanism, improve innovation vitality, actively introduce advanced technology and management, improve the quality and efficiency of production and service, and continuously enhance market reputation and competitiveness.
(3) Improve the market economic system through bidding.
Maintain and standardize the market competition order, protect the legitimate rights and interests of the parties, improve the fairness, satisfaction and credibility of market transactions, promote the rule of law and credit construction of society and enterprises, promote the transformation of government functions, improve administrative efficiency, and establish and improve the modern market economic system.
(4) Combating corruption through bidding.
It is conducive to protecting the interests of the state and society, ensuring the rational and effective use of state-owned funds and other public funds, preventing their waste and loss, building a social supervision and restriction system, and preventing corrupt transactions from the source. In the initial stage of the construction of public procurement system in countries all over the world, the bidding system can often have an immediate effect on combating corruption because of its standardized and open procedures. However, with the deepening of the game between corruption and anti-corruption, corruption will exist in a more hidden form, which poses new challenges to the designers of bidding system.
