Results indicate that: (1) both resource sharing, task collaboration can promote long-term cooperation intention.(2) the resource sharing, task collaboration can cause the trade conflict behavior in the late of cooperation.(3) the contract governance has a negative moderating effect for the enterprises-client interaction and inter-organizational relationships, but this effect has no significant difference between resource sharing and collaborative task. (4) Relationship governance has a negative moderating effect on the relationship between resource sharing, task collaboration and the long-term cooperation intention, but has no effect for trade conflict behavior.
