Abstract: With the rapid development of modern science and technology, cooperation has become the mainstream way of scientific research. The academic community has carried out systematic researches on the influencing factors of scientific research cooperation, but little attention has been paid to the sustainability of cooperation among scientific researchers. This paper takes the authors of the 118 two-author papers published by Studies in Science of Science in 2010 as samples to analyze the sustainability characteristics of the scientific researchers who have already carried out academic cooperation. The results show that the sustainability of academic cooperation between researchers is relatively low, with only 6 pairs of researchers forming a lasting academic partnership, 4 pairs being supervisors and students, and 2 colleagues. In order to promote the continuous academic cooperation among scientific researchers,we suggest changing that the existing scientific research evaluation system that emphasizes the first author alone, and co-authors signing their names in alphabetical order or according to the actual contribution to the paper. We also suggest changing the current professional title evaluation system to a qualification competition in which every researcher can be promoted when meeting the requirements of a higher title.

Key words: scientific researcher, academic cooperation, sustainability, supervisor-student relationship, colleague relationship
