摘要

The data was derived from Science Citation Index-expanded of Thomson Reuters. We choose special international collabora-tion articles participated by Chinese and American from 2006 to 2011 as sample, analyze the Hong Kong's contribution to Sino-USA col-laborative articles and the dimension structure of these articles, define and find the most important subjects in China transforming from No. 4 to No. 1 in America's collaborating countries in science, and discuss the cause of transformation viewed from scientometrics using Salton Index.%以Thomson Reuters公司的Science Citation Index-expanded为数据源，选取2006-2011六年的中美合作论文为样本，从科学计量学的视角分析了香港对中美合作论文增长的贡献，中美合作论文的维度结构，并从平均增长量和平均增长速度两个方面，确定了对中美合作论文贡献最大的学科领域。最后，探讨了中国成为美国第一科学合作国的原因。
