From the perspective of developer, and on the basis of analyzing the risk factors of real estate project prophase, this paper builds a index system and establishes the risk assessment model based on BPNN, then selects several sets of samples as the training set and trains the model in the MATLAB7.0, finally verifies the feasibility of the model in the risk evaluation of real estate project prophase by using the test set.
