Practical legislative activity in the application of Public-private partnership is based on the principles of scale for the subjects of implementation, the scope of work or services, geographical and political and economic characteristics. Currently, there is an experience of successful implementation of projects of regional, Federal and international importance. In the conditions of the applied practice, certain elements of the imperfect legislative mechanism were revealed, which subsequently underwent regulatory and legal revision. Methodical recommendations, expert opinions at the places of execution of the project stages, which have become fundamental in the adoption of certain legislative initiatives by the Executive authorities, have been developed. The principle of priority consolidates the attention of lawmakers to strategically important projects for the state, highlighting no less important areas of social activity in the field-municipalities (territorial Executive authorities), also in need of intellectual support of management tools.
