It　is　very　difficult　and　time-consuming　to　resolve　the　conflicting　objectives　in　the　process　of　negotiation.　Although　there　are　many　automatic　negotiation　systems　based　on　Agent,　the　strategies　in　most　negotiation　models　are　static.　With　the　changing　market,　a　multi-lateral　model　based　on　market-driven　negotiation　is　proposed,　which　can　make　different　concession　through　considering　factors　such　as　time,　competition　and　the　trading　opportunity　in　the　market.　Simulation　shows　that　the　model　can　achieve　higher　success　rates　in　reaching　a　deal　and　higher　utilities　than　fixed　rate　concession　negotiation.　©　2011　IEEE.
