The catalogue of government procurement is a list of the scope and specific names of goods, projects and services that are determined by the relevant government procurement authorities according to the principle of improving procurement quality and reducing procurement cost, and should be included in some general and large-scale procurement targets of government procurement management and centralized procurement, and announced by government departments.

Government procurement catalogue can be divided into centralized government procurement catalogue and centralized departmental procurement catalogue. Government procurement projects within the central budget shall be determined and published by the State Council; Government procurement projects belonging to local budgets shall be determined and published by the people's governments of provinces, autonomous regions and municipalities directly under the Central Government or authorized institutions.

Scientifically and reasonably formulate the catalogue of centralized government procurement;

1. Further investigation and study. The catalogue of centralized government procurement should fully reflect the actual local procurement situation, correctly distinguish the dialectical relationship between impossible and possible, and scientifically and reasonably arrange the procurement catalogue in combination with the affordability of procurement institutions. If the project procurement is indeed difficult, it should be postponed until the conditions are ripe to maintain the authority of the Catalogue.

For some projects with business development prospects, such as agricultural materials, bulk relief materials, fire-fighting equipment, police equipment, teaching equipment, etc. Although the purchaser's demand has a gradual process, as a complete annual centralized procurement catalogue, these contents should be fully covered.

2. The content should be coarse and not fine, and the procurement items should be few and not many. If the procurement project is arranged in many details, on the one hand, it is difficult to cover all the procurement contents, and it is easy to miss items, and it is easy to misunderstand or argue about new technologies, new products or things that can't be thought of, found, written or done later, and it is also difficult to operate.

On the other hand, the content is too detailed, which often leads to a heavy workload and a waste of time. In centralized procurement, goods are only listed as Grade I and Grade II, and three-level catalogues are added to engineering and service categories, which can generally meet the requirements. In this way, there is room for adding, deleting and deleting specific purchases.
