Abstract: Using I-U cooperative patents of organic chemical industry, this paper analyzes the patent map and constructs negative binomial regression models based on unbalanced panel data, the models use enterprise’s independent innovation performance(IIP) as dependent variable. Through the models, this paper study how the enterprise’s relational potential energy (RPE) influence the IIP and inspect how the geographic boundary spanning of enterprise’s cooperative network moderates the relationship between RPE and IIP. The results show that organic chemical industry has grown slowly in recent years and geographic boundary is spanning, the direct tie scale and the indirect tie strength both have positive effects on IIP, the geographic boundary spanning moderates the relationship between the indirect RPE and IIP.

摘要： 本文采用中国有机化学行业的产学合作专利数据，进行专利地图分析，并以参与产学合作的企业的自主创新绩效为因变量，构建非平衡面板数据下的负二项回归模型，研究企业的关系势能对企业自主创新绩效的影响，并考察企业合作网络的地理边界拓展对二者关系的调节作用。分析结果发现我国有机化学行业的产学合作近几年增速放缓，且已呈现出地理边界拓展的形态，回归结果支持了部分假设：企业的直接关系规模和间接关系强度与企业自主创新绩效正相关，企业合作网络的地理边界拓展正向调节间接关系规模、间接关系强度与企业自主创新绩效的关系。
