The　efficient　travel　demand　management　is　more　important　than　traffic　congestion　control.　Currently,　tour　reservation　system　(TRS)　based　on　demand　response　has　become　a　significant　part　of　travel　demand　management.　The　Integrated　Travel　Reservation　Information　(ITRI)　released　by　TRS　plays　an　important　role　in　the　decision-making　process　of　tourist＇s　holiday　travel　destination　and　departure　time　choice　behaviors,　which　is　seldom　investigated.　To　fill　this　gap,　this　paper　explored　the　feedback　mechanism　among　the　ITRI　usage,　tourism　utility　of　various　alternatives　and　tourist　decision-making　behavior　based　on　the　Engel-Kollat-Blackwell　(EKB)　consumer　purchase　decision-making　model.　To　quantify　the　impact　of　ITRI　on　travel　behavior,　a　revealed　preference　and　stated　preference　survey　were　designed　and　carried　out　in　China.　The　data　show　about　80%　of　tourists　are　concerned　about　the　information　of　tickets　sold　ratio.　Nested　Logit　(NL)　model　for　the　joint　choice　of　destination　and　departure　time　was　established,　which　accounted　for　the　impact　of　TRS　and　ITRI　on　the　utility　of　alternatives.　The　NL　model　results　reveal　that　tourist＇s　age,　education　level,　number　of　visits,　ITRI　content,　ITRI　query　method　and　the　tickets　sold　ratio　have　significant　effects　on　destination　and　departure　time　choice.　Especially,　sensitivity　analysis　results　reveal　that　when　the　tickets　sold　ratio　reaches　65%,　75%,　85%　and　95%　respectively,　every　1%　growth　of　tickets　sold　ratio　is　accompanied　by　2.858%,　2.877%,　3.015%　and　3.362%　increase　in　the　probabilities　of　traveling　during　non-holiday　periods.　Therefore,　tourists　are　encouraged　to　travel　during　non-holiday　periods　by　tickets　sold　information　release,　which　can　achieve　the　rational　allocation　of　tourism　resources　and　enable　to　make　maximum　use　of　tourism　resources.　Further,　the　results　can　provide　a　basic　data　for　development　of　the　tourism　demand　management　and　equilibrium　of　the　tourist＇s　spatial　and　temporal　distribution.
