2. The concept of bidding negotiation itself is a pseudo concept, and direct procurement under the banner of bidding has nothing to do with bidding. What is negotiation? It should be related to bidding, but it doesn't want to bid at all.
3. The Bidding Law itself has ruled out the concept of bid negotiation, and there is no regulation on the management of bid negotiation. Bidding negotiation is not a standardized procurement behavior even compared with competitive negotiation, price comparison and comparison. More directly, bidding negotiation is a black-box operation, which is the default and is not worth advocating.
