The　inconsistence　of　SP　data　between　behavior　and　behavior　intention　is　a　serious　problem.　The　article　introduces　the　method　of　revises　the　SP　data　using　the　RP　data.　Then　take　Beijing　as　the　example,　establishes　the　RP　data　models,　the　SP　data　model　and　the　fusion　data　model,　it　carries　on　the　analysis　of　model　sensitivity.　The　results　indicate:　the　mark　of　expense　parameter　is　not　logical　in　the　RP　data　mode;　The　precision　of　SP　data　model　is　high,　but　the　effects　of　some　parameters　are　not　remarkable;　The　fusion　data　model　parameters＇　test　are　remarkable,　the　model　elasticity　is　small,　and　its＇　sensitivity　is　deactivated.
