Results indicate relationship fairness and relationship persistence produce more economic based trust and influence cooperative innovation performance through it; Relationship intensity generates more emotion based trust and influence cooperative innovation performance through it. Interaction of economic based trust and radical innovation has positive effect on cooperative innovation performance; Interaction of emotion based trust and incremental innovation benefits to cooperative innovation performance. This study clarify the relationship between state and content dimension of bilateral relationship quality, reveal match mode between bilateral relationship quality and technology innovation, provide theoretical support to follow research on the relationship between multidimensional cooperation relationship and cooperative innovation performance.
