Here, I also talk about my own views.
SCI division of China Academy of Sciences is divided according to influencing factors. If I remember correctly, the top 5% should be 1 area, which is also the most criticized place. As far as my research direction is concerned, the threshold of 20 13-year physics 1 zone: 3-year average if: 6.711; Area 2: 2.490; Zone 3: 1.453 and 1 last physical review x. Many people spit out that physics review B is actually the second district. I have to say that PRB is a very good physics journal, but it is really worse than the magazine in 1 area, and it can't reach the top 5%. It is normal to be divided into two areas.
SCI division of China Academy of Sciences is divided according to the influencing factors of different disciplines, which has certain limitations. However, compared with the evaluation based on people's recognition of different disciplines, human factors will be much less and the operation will be much more convenient. Otherwise, who can identify these journals and how many people can be found? These are all problems. In China, if there are no fixed indicators, people can only rely on interpersonal relationships to evaluate, and the more shady.
In fact, this question is a bit like the fairness of the college entrance examination. Although there are many unreasonable places, this is the fairest way. There are also a large number of SCI papers on the evaluation of professional titles, scholarships, application for funds and other influencing factors as the main reference, which is actually the most convincing way for everyone, otherwise we may get nothing.
So, let's be considerate. If one day people decide to partition, there may be more people complaining. In fact, we know which ones are in the 1 area. Let's try to publish more articles in the 1 area (there are many benefits, so I won't explain them), so that we can contribute articles that you think are easy to win in the 1 area, and no one will stop us, right?
