Abstract Taking open innovation situation as the research background, we explore the relationship among innovation partner heterogeneity (including organizational type heterogeneity, technological ability heterogeneity and target heterogeneity), dual organization learning and open innovation performance. On the basis of the proposed model, we tested it by means of 284 valid samples. The empirical analysis results showed that innovation partner heterogeneity and technological ability heterogeneity have an inverted U-shaped relationship with open innovation performance. Target heterogeneity has a negative effect on innovation performance. Moreover, dual organization learning plays an intermediary role in the relationship between innovation partner heterogeneity and innovation performance. However, the relationship and affecting extent between segmentated dimensions of innovation partner heterogeneity (organizational type heterogeneity, technological ability heterogeneity, and target heterogeneity) and learning style (exploratory learning and exploitative learning) is different significantly.
