According to the conventional understanding, the periodicals in the second area of SCI may not be top periodicals, because the periodicals in the first area have higher impact factors, higher publishing level and higher value. However, if the number of top journals is not clearly defined by academic circles, generally speaking, the top five journals should be considered as top journals, or there are also top journals in the second district of SCI if there is no comparability standard within this major.

In other words, the strength of the top journals in the second district lies in their high impact factors and high rankings in this district, and they are recognized as top journals in this district. Therefore, it is difficult to publish the top journals in the second district, but it will be helpful for personal academic achievements and career development.

Whether the periodicals in the second district of SCI belong to the top periodicals mainly depends on the evaluation criteria. According to the conventional understanding, the periodicals in the second area of SCI may not be the top periodicals. But the magazine in the first district is better than the second district, and the second district is better than the third and fourth districts. But there are also great individual differences in the magazines in the second district. There are many high-level top magazines in the second district, and their level and influence in the industry are easily higher than that in the first district. Therefore, there are also views that there are also top journals in the second district of SCI.
