中国高校知识合作网络演化特征与影响因素研究

利用社会网络分析、地理空间分析和随机面向对象模型，基于2006年与2016年中国高校合作论文数据，探究中国高校知识合作网络演化特征及网络演化影响因素。研究表明：中国高校间合作日益频繁，高校知识合作网络演化处于活跃期；高校知识合作网络具有小世界特征，网络呈现出核心—半边缘—边缘结构，985高校和211高校占据网络重要位置；网络联系呈现出东密西疏的空间结构，联系强度存在地理距离衰减规律；高校知识合作网络存在7个内部成员较为稳定的高校社团，社团具有空间连片式集聚特征；中国高校知识合作网络演化受网络结构、多维邻近性以及高校自身特征等因素的影响，最为关键的推动因素是地理邻近性、互联网发达程度、认知邻近性和制度邻近性。

Evolution's Characteristics and Influence Factors of China's Universities Knowledge Collaboration Network

By utilizing the methods of geospatial analysis,social network analysis,and stochastic actor-oriented model,and using the amount of papers co-authored data of Chinese university in 2006 to 2016 as the basic data,this paper probes into the evolution's characteristics and influence factors of China's universities knowledge collaboration network.The researchfound that: Cooperation have become increasingly frequent in China's universities knowledge collaboration network,it currently experiencing the active period.China's universities knowledge collaboration network has a small-world feature.China's universities knowledge collaboration network presents a core-periphery structure with hierarchies,985 project universities and 211 project universities have always taken an important position in the network.In the spatial pattern,the network connections are dense and strong in the east but sparse and weak in the west,the spatial relationship of universities shows a certain attenuation law of geographical distance.China's universities knowledge collaboration network is made up of seven relatively stable university communities,the structure of university community has the characteristics of a regional aggregation which shows spatial development and spatial distribution.The structural characteristics of the university's knowledge cooperation network,the university's own attributes and the proximity of each dimension of the university have promoted the evolution of the network.The most critical factors that promote colleges to maintain or establish knowledge partnerships are geographic proximity,internet development degree,cognitive proximity,and institutional proximity.
