Based　on　the　survey　of　Beijing　tourist　travel　motivations,　the　factor　analysis　were　used　to　identify　the　underlying　dimensions　of　tourism　motivations.　The　paper　presents　a　concept　model　which　investigates　the　relevant　relationship　among　motivations　and　activities　by　structural　equation　modeling　approach.　The　results　show　that　the　social　and　consumption　factor　have　a　greater　positive　impact　on　the　non　visiting　and　recreational　factor,　while　it　have　little　effect　on　visiting　and　recreational　factors;　cultural　factor　has　a　positive　impact　on　visiting　and　recreational　factors　and　has　no　significant　effect　on　non　visiting　and　recreational　factors.　Escape　and　relax　factors　exert　negative　effect　on　non　visiting　and　recreational　factors,　and　have　less　effect　on　visiting　and　recreational　factors.　The　research　demonstrates　that　there　is　a　causal　relationship　between　the　levels　of　motivation　and　decision-making　activities,　and　it　provides　a　basis　for　study　of　tourist　activities　decision.
