However, it is difficult to share information in practice, except information technology, other reasons exist. Supply chain members are pursuing maximum profit and minimum cost in trust-agent relationship, which leads to converse choice and moral risk; the odds of benefit weakens the enthusiasm of supply chain members, which makes them inactive. Information sharing increases members'cost; the structure of supply chain is very complicated, which makes information sharing more difficult; culture diversity is also a obstacle to information sharing.Information sharing needs members to construct their relationship from a strategic point and overcome obstacles in techniques and management, so that the performance of the whole supply chain can be enhanced.
