2. It is convenient to standardize the purchase behavior. Whether the government procurement behavior is standardized not only affects the fairness of public bidding for government procurement, but also directly affects the image of the government, and even involves the quality of bidding procurement services, which is related to the national economy and people's livelihood. Public bidding procurement, the working procedures are relatively standardized. Publicizing on social media and selling tenders publicly before bidding can expand and protect suppliers' right to know as much as possible, mobilize more suppliers to participate in the competition, and make qualified suppliers fully compete; When opening bids in public, the confidentiality is enhanced to the maximum extent, so that all suppliers participating in the bidding can compare prices at the same "starting line", which relatively ensures fairness; The public bidding after the bid opening not only publicly announces the bidding prices of all bidders, but also fixes the quotations of suppliers, thus putting an end to the phenomenon of "black-box" quotation adjustment; When evaluating bids, the judges comprehensively evaluate and uniformly select the bidding candidates, which overcomes the problem that individuals have the final say. A series of standardized procedures make the bidding work more rigorous, scientific and relatively fair, which is also the main reason why the public bidding of government procurement has been unanimously recognized.
3. It is convenient to standardize the performance of suppliers. Selling the public bidding documents and the main terms of the contract to suppliers at the same time, so that suppliers can make quotations on the basis of fully understanding and agreeing with the requirements of bidding services, can not only enhance suppliers' ability to make substantive responses, but also effectively standardize suppliers' performance behavior. When signing a contract after bidding, in addition to signing a written agreement on the business requirements and payment methods in procurement, the supplier's various commitments are fixed by law on the basis of collecting a certain amount of performance bond, so as to constrain the supplier to conduct business operations according to the bidding price and ensure the requirements of procurement quality.
4. It is convenient for public supervision. In addition to the direct participation of notary departments, supervision and discipline inspection departments and financial supervision and management departments, user units, social news media, industry and commerce, price and technical supervision departments can also cooperate with supervision and urge buyers and sellers to operate according to law. This makes government procurement activities open under the "sunshine" and eliminates the conditions of "black-box operation".
5, easy to save money. The biggest advantage of public bidding lies in bargaining purchase, and the purchased goods are worth the money. According to the analysis of the operation law of the market, savings are mainly reflected in three aspects: first, bidding procurement generally belongs to large-scale procurement, which often gets preferential treatment from manufacturers; Second, government procurement bidding is a fixed payment method in the form of contract, so there is no need to worry about default. Even if you sometimes pay in installments, you are very cautious. Suppliers themselves don't have to pay money, which can reduce the investment cost, so they should get the preferential price of supply. Third, in order to win the bid, as long as all businesses can make small profits but quick turnover, they will try their best to reduce product costs, reduce labor prices and provide better service conditions to win competitive advantages. Practice has proved that the saving rate of government bidding procurement is generally higher than other procurement forms.
6. The above are the advantages of public bidding, but the disadvantages are: the preparation of procurement texts is complicated and it is not easy to comprehensively consider. Sometimes, the poor plenary meeting will put the purchaser or supplier in an awkward position and even lead to the failure of bidding. The bidding procedure is complicated and takes a long time. Once the bid fails, it will waste at least one month.
