本文以129家国家工程技术研究中心的数据为样本，通过2007-2010的运行数据，以网络构建的不同地理位置为视角，探讨了国内协同创新网络规模、国际协同创新网络规模以及两者之间的平衡度对创新绩效的影响。研究结果显示，国内协同创新网络规模和国际协同创新网络规模与创新绩效之间的关系均呈现“倒U型”结构；同时，地理位置网络平衡度对创新绩效存在显著地正向影响。本文通过国内和国际不同的协同创新网络刻画组织间的多元关系及其对创新绩效的影响，并首次验证了地理位置网络平衡度对创新绩效的正向作用。这为协同创新提供了不同的视角，也为企业如何构建协同创新网络提供了指导。

From the perspective of geographic network, we use Chinese National Engineering Research Centers (CNERCs) as sample to explore the impact of local innovation network, foreign innovation network and its balance on innovation performance. The results show that relations between local/foreign innovation network and innovation performance are “inverted U-shaped”. In addition, Geographic network balance has a positive effect on innovation performance. This paper characterizes organization’s pluralism relations by local/foreign innovation network and testes the positive effect of geographic network balance on innovation performance for the first time, which provides a different perspective for collaboration innovation study and guidance for enterprises how to choose collaboration innovation network.on innovation performance.
