By the end of March 2022，a total of 425 2021 pishu had participated in the pishu evaluation. In terms of content classification，there are 150 kinds of local development pishu. The number of cultural and media pishu is the least，accounting for less than 10%. From the perspective of research and innovation institutions，the research and innovation of think tanks of the Chinese Academy of Social Sciences，universities and colleges，think tanks of local academies of Social Sciences，party and government departments and their think tanks account for more than 80% of the total varieties，and the quality is relatively high. Compared with previous years，the evaluation of the 2021 edition of pishu is based on peer review. The subjective indicators and comprehensive evaluation use the evaluation rating method instead of the specific scoring method for the first time. Among the pishu involved in the evaluation，55 kinds of pishu are better，with the grades of a+and a. The 308 seed coat pishu ranks B+and B；The 62 seed coat pishu is relatively poor，and the grade is C+and C. Among them，the number of economic pishu at B+and above accounts for 66.2% of the total number of pishu in the category，accounting for the largest proportion. The number of local development pishu at B + and above accounts for 47.3% of the total number of local development pishu，accounting for the smallest proportion. Through the analysis of the subjective indicators of various types of pishu，it is found that the number of leading-edge and innovative indicators with higher evaluation levels is the least；Through the analysis of objective indicators，it is found that the number of timeliness indicators with higher evaluation levels is the least，which needs to be supplemented and improved when writing the report. In view of the style specification and frame structure problems in the paper report，it is suggested that the research and development unit make a good publication plan and emphasize the writing requirements of the report when soliciting contributions；In view of the tendency of academic papers，government work reports and technical analysis reports in some reports，highlight the think tank characteristics of the paper report；In view of the fragmentation，similar or overlapping themes of some of the pishu，the management needs to be further strengthened.
