选取2008~2012年5年间计算机领域核心期刊的刊载论文作为样本，运用社会网络分析等方法，从网络整体、合作密度、城市地理距离、城市科研能力等几个方面对我国城市间的科研合作进行研究。研究表明，中心城市在我国城市间科研合作中的地位十分重要，目前我国城市间的合作关系较为广泛，但大部分并不紧密。同时，地理距离较近的城市间的合作倾向更为明显，科研能力越强的城市与其他城市的合作也越频繁。%This paper studies inter city scientific collaborations in China by analyzing papers from core journals in the field of computer science from 2008 to 2012.Using social network analyzing approach (SNA), the disclosed characteristics of inter city scientific collaborations are network topology, density, geographic distance and scientific capacity.
