Cooperation networks are social networks consisting of a lot of collaborators to achieve better researches in science，engineering or other related fields．In cooperation networks，there are three probable attachments：random，preferential，and the mixed attachments．This paper analyzes the data of GR-QC network，and evaluates the attachment probability of the random，the preferential and the mixed．A novel collaborative network model driven by the attachment behaviors is presented．Compared with data of GR-QC，the attachment behaviors of scientists of management science and engineering in China have similar trends．Numerical simulations show that the attachment behaviors are affected by the average degree of the network，and the attachment behaviors evolves with the structure of the network．Discussing the numerical simulations and real data，the paper finds that the diversity and the homobium of attachment behaviors may cause the giant component to emerge or the distinct communities'to become cooperation networks．
