该文旨在测度天文学领域主要国家在国际合作网络中的影响力。文章定义了合作网络中影响力的两个维度——合作广度与合作强度,利用赋权网络点度中心度算法,提出了综合评估合作广度和合作强度的网络影响力指数,对天文学主要国家的影响力进行测度。研究发现,国际合作是天文学领域的主要研究模式;参与大型天文观测设备合作建设是智利、南非等国家迅速融入学术共同体的“捷径”;天文学领域的国际合作在向广度和强度两个方面并行发展;中国在天文学领域越来越多地融入了国际交流中,但仍需大力加强国际合作研究。

This paper aims to measure the impact of major countries in the field of astronomy based on international collaboration network. Firstly, the two dimensions were defined as amplitude and intensity to describe the impact for countries within collaboration network. Then on the basis of weighted network centrality algorithm, this paper designed a combined index (amplitude and intensity) to evaluate the impact of the country in collaboration network. The main conclusions of this study is below: (1)International collaboration is the main research pattern in astronomy field; (2)For Chile, South Africa, constructing large astronomical facilities is the shortcut to come into the academic community rapidly; (3)International collaboration in the field of astronomy developed from two parallel directions- amplitude and intensity; (4)Though Chinese researchers participated more international collaborations, compare to other developed countries, the international collaboration need to be continued strengthen.
