本文表明，科学团队合作越来越多地跨越大学的界限，知识生产的戏剧性转变，概括了几乎所有领域的科学，工程和社会科学。此外，精英大学在这一转变中发挥了主导作用。通过研究30年来发表的420万篇论文，我们发现，多大学合作（i）是增长最快的作者结构类型，（ii）当它们包括顶级大学时，产生最高影响力的论文，（iii）越来越多地按组内大学排名分层。尽管跨越大学边界的研究频率不断上升，但多所大学合作中社会分层的加剧表明，科学知识的生产集中在更少而不是更多的高影响力科学中心。
This paper demonstrates that teamwork in science increasingly spans university boundaries, a dramatic shift in knowledge production that generalizes across virtually all fields of science, engineering, and social science. Moreover, elite universities play a dominant role in this shift. By examining 4.2 million papers published over three decades, we found that multi- university collaborations (i) are the fastest growing type of authorship structure, (ii) produce the highest- impact papers when they include a top-tier university, and ( iii) are increasingly stratified by in- group university rank. Despite the rising frequency of research that crosses university boundaries, the intensification of social stratification in multi- university collaborations suggests a concentration of the production of scientific knowledge in fewer rather than more centers of high- impact science.
