考虑到农林类高校在农业科研与农业创新技术研发方面所发挥的举足轻重的作用，本文以国内41所农林类高校2005-2016年发明类专利申请数据为样本，在构造其合作网络和知识网络的基础上，深入探讨了这两个网络的结构洞和度中心性属性对高校创新绩效的影响。研究结果表明：在合作网络中，申请人的结构洞和度中心性都与高校创新绩效具有显著的倒U形关系，申请人的度中心性与结构洞平方项的交互作用对农林类高校创新绩效具有显著的负向调节作用，申请人的结构洞与度中心性平方项的交互作用对高校创新绩效具有显著的正向调节作用；在知识网络中，知识元素的结构洞和度中心性都与高校创新绩效具有显著的倒U形关系，知识元素的度中心性与结构洞二次方的交互作用对高校绩效创新具有显著的负向调节作用。

Considering the decisive role of agricultural and forestry universities in agricultural scientific and research and innovation R&D, using the 2005-2016 invention patent application data (43248 records) of 41 agricultural and forestry universities collected by the national key industry patent database, the cooperative networks and knowledge networks are constructed respectively. Moreover, the effects of structural hole and degree centrality on the innovation performance of agricultural and forestry universities in cooperative networks and knowledge networks are studied respectively. The main findings of this paper show that in the cooperative network, the applicant''s structural hole and degree centrality have a significant inverted U-shaped relationship with the innovation performance of the university. The interaction between the applicant''s degree centrality and the structural square square term is for the agricultural and forestry colleges. Innovative performance has a significant negative adjustment effect. The interaction between the applicant''s structural hole and the central squared term has a significant positive adjustment effect on the innovation performance of colleges and universities; in the knowledge network, the structural hole and degree of the knowledge element Both have significant inverted U-shaped relationship with the innovation performance of colleges and universities. The interaction between the centrality of knowledge elements and the quadratic structure of structural elements has a significant negative adjustment effect on university performance innovation.
