Abstract: Based on eight engineering departments in Tsinghua University, this paper tries to investigate how social capital affect the research output and the associations between different dimensions of social capital. The results indicate scientists with higher structural dimensions in co-authorship networks have higher citation count. Due to discipline differentiation, relational capital and cognitive capital are positively related to citation count in some departments. The associations between relational, cognitive capital and structural capital are positive to some extent, which may help scientists to obtain advantage positions in co-authorship network.

摘要： 本文从社会资本理论出发，以清华大学8个工科院系为对象，研究了社会资本是如何影响学术产出成果以及不同社会资本维度之间的相互关系。研究结果表明：社会资本的结构性维度对于学术成果产出具有正向的促进作用，由于学科特征差异，关系性维度和认知性维度对于学术成果的正向影响在部分院系显著。关系性维度和认知性维度在一定程度上对结构性维度有着正向的显著影响，从而帮助科学家获得有利的网络位置。
