The article proposes a tool for assessing the efficiency of the implementation of public-private partnership mechanisms in the high-tech industry including aerospace. The paper presents a tool to assess the efficiency of public-private mechanism and the change of the efficiency estimation. Having the predicted pathway of the change in the efficiency evaluation, it is possible to monitor the real values of the indicator in the course of a project implementation, using the public-private partnership mechanism. Such monitoring will reveal significant deviations from a pathway, which can be of two types: deviations, excessing the actual values of an indicator over the predicted values and deviations, failing to achieve the real values of the predicted indicator. © 2019 Published under licence by IOP Publishing Ltd.
