The methodological foundations of microeconomic analysis of the project form of innovative investment activity are developed in the article. The concept of time acquisition of economic resource properties in the process of realization of an innovation-investment project is proposed. The concept of production function of project innovation-investment activity introduced by the author has been clarified and improved. Its properties have been defined. It is determined that the choice of the owner of an investment project for the term of its realization is in fact the choice of a way of placing in the time necessary for its realization of a contracting resource under the appropriate organizational and technological scheme of work execution. This choice is influenced by subjective and objective factors. The latter form the main criterion for the above selection. This is a criterion for minimizing the economic value of the project, which should be understood as the future value of the entire cost of its implementation, including implicit ones. The structure of the economic value of the project is analyzed in detail, the formation procedure and the interdependence of its components, are determined. As a result, it is established that the economic value of the project is played by two resources - contracting and temporary, so its value depends primarily on the value parameters of these resources - specific value added and interest rate. The process of optimizing the economic value of an innovation investment project initiates its implementation and is carried out according to the criterion of consensual coordination of the approaches of the contractor and the project owner to establish the contractual values of the main parameters of its implementation, that is, the result of interaction of participants trying to achieve the project goals in the most rational way economic interests. This can be achieved by determining the cost of contracting resources, based on the ratio of supply and demand for the project and the project implementation time, taking into account the value and/or pressure of the time factor.
