Abstract: The lack of price supervision is a major reason for the artificially high procurement prices and it is also the resource of the impracticable legal provision that “the government procurement price should be lower than the average market price”. The paper proposed a new price supervision model which computes the procurement warning price based on procurement auction theory. Compared with the method of monitoring the procurement price using average market price, our method considers the competing factors of market environment and bid environment. The positive analysis of the goods in Tianjin Government Procurement Center from August 2012 to July 2013 reveals that the model has high fitness and robustness. A Monte Carlo simulation verifies that the model improves the detection rate of abnormal procurements. The model provides an efficient and liable precautionary and warning mechanism for the government procurement in China.
