target. The Natural Science Awards focus on originality, recognition and scientific value. The Technology Invention Awards focus on innovation, advancement and technological value. The Science and Technology Progress Awards focus on innovation, application efficiency and economic and social values, and are classified according to the quality and contribution of scientific and technological innovation . Evaluation index system. The Natural Science Award, the Technical Invention Award, and the Science and Technology Progress Award (hereinafter collectively referred to as the “Three Awards”). The first and second prizes are subject to a nomination and independent review and voting mechanism. The nominees are nominated strictly according to the standard conditions, indicating the degree of contribution of the nominees and the awards and grade recommendations. The judging experts strictly followed the evaluation criteria, and voted independently for the first prize and the second prize respectively. The first prize nominations were no longer degraded to participate in the second prize.

quota. Significantly reduce the number of awards, the total number of three major awards reduced from no more than 400 to no more than 300, encouraging scientific and technical personnel to study hard. Change the current awards and their awards in various fields and the number of acceptances according to the established ratio. According to the actual situation of China's scientific research input and output, scientific and technological development level, etc., the number of awards for the first and second prizes of the three awards will be respectively limited, and the rewards will be further optimized. structure.

Change 3

Adjust the reward object requirements

The three awards are changed from “citizens” to “individuals”, and the number of awards and the number of units required for each award result are adjusted. The classification determines the practical test period requirements for the nominated scientific and technological achievements, eliminates the intermediate results awards, and the same results may not be repeatedly reported.

Change 4

Clarify the responsibilities of expert review boards and government departments

The expert review committees at all levels perform the technical review duties of the candidate results (persons), are responsible for the results of the review, and give full play to the independent review of peer experts. The government department is responsible for formulating rules, standards, and procedures to perform the organization, service, and oversight functions for the review activities.

Change 5

Enhance the openness of reward activities

With the exception of openness and non-disclosure, the public will be open to the whole society for the award policy, the evaluation system, the review process and the number of indicators. The three major candidates and their nominees will be publicized on a full-scale basis, and will be supervised by the community, especially the scientific and technological community. Establish a post-evaluation evaluation system for science and technology rewards. After the annual National Science and Technology Awards Conference, entrust a third-party organization to evaluate the annual award work and promote the continuous improvement of science and technology awards.
