The invention provides a method and a system for recognizing new buildings. The method comprises the following steps: acquiring engineering vehicles having stopping behaviors; marking stopping pointsof the engineering vehicles; acquiring a first driving path corresponding to each engineering vehicle having the stopping behaviors; acquiring a corresponding first driving path set; judging whether aphenomenon that driving paths are gathered in the first driving path set occurs or not; if so, acquiring a corresponding first driving region; judging whether the number of marked stopping points within the first driving region is greater than or identical to a preset stopping point number threshold or not; if so, matching the first driving region and map data, and acquiring locations of the newbuildings. With the application of the method provided by the invention, information on the new buildings in a specific region can be recognized out in a targeted mode in accordance with different requirements of a user, so that the third party, a traffic administrative department or a navigation system is facilitated.
