Abstract: Using Williamson s transaction-cost theory, the characteristics of virtual enterprise strategic behavior relationship under inconsistent bilateral regulations were analyzed. The contractual relationship model restricted by both strong contract and week contract was built. Based on graph theory, triple concept was introduced to describe the dynamic contractual relationship within virtual enterprise system, and a relationship schema based on core-teamandcooperation-objectlibrary was constructed. Applying permutation matrix, the association and the system isomorphism between contractual relationship modeling in theory and its operation in practice were verified. By applying the set of arc, the key role the transitive closure played in contractual relationship model was proved, and the recursive and reflective rules in virtual enterprise system were validated. At last, some product supply chain was presented as an example to illustrate the collaboration policy in contractual relationship, its model s actual construction and its operation process.
