Why is there something fishy about tendering?

According to my country's "Tendering and Bidding Law": "The following engineering construction projects carried out within the territory of the People's Republic of China include the survey, design, construction, supervision of the project and important equipment related to the engineering construction, The procurement of materials, etc. must be subject to bidding. lt; 1 gt; Large-scale infrastructure, public utilities and other projects related to social welfare, public safety and other projects; lt; 2 gt; Use state-owned funds for investment or state financing in whole or in part. Projects using loans and aid funds from international organizations or foreign governments. "

According to my country's "Government Procurement Law": ""Government procurement adopts the following methods: (1) Disclosure. Tendering;

(2) Invitation to tender; (3) Competitive negotiation; (4) Single-source procurement; (5) Inquiry;

(6) Government procurement supervision and management by the State Council Other procurement methods recognized by the department. Public bidding should be used as the main procurement method for government procurement. ”

So based on the above situation, many procurements in our country need to be conducted in the form of bidding. This is a basic requirement of the country. Therefore, no matter what the specific purchaser thinks, the bidding must be carried out in accordance with the requirements. This is not It is up to a certain purchasing unit to determine. As for matters such as pre-determination, black-box operations, and fake bidding, relevant participants can only report and complain in accordance with national regulations.
