The goal of this article is to substantiate the reasonability of using the project financing (as a new and the most progressive form of investments) for stimulating the entrepreneurial activity in the Russian venture segment. Based on the materials stated herein, it is possible to formulate the following basic conditions: • Innovation activity and development of venture entrepreneurship are the most principle conditions that provide the macro-economic stability and balanced economic growth, • Venture entrepreneurship in Russia has not yet been sufficiently developed, which is related to including the incomplete process of forming the innovation infrastructure required for implementing progressive innovation ideas, • Insufficiency and in some cases non-availability of investment resources seriously hinders the activation of innovation activity in the entrepreneurial segment, • Project financing is an optimal form to attract investments in the innovation activity, as well as in commercially successful programs and projects offered for the implementation by venture entrepreneurs, and • Becoming of the institute of project financing requires changing approaches to crediting small and medium-sized entrepreneurship by Russian commercial banks and other financial and investment structures. Besides, project financing requires changes in the state economic and financial and credit policy, which is important to pursue now. © 2017.
