Without investment in infrastructure, it is impossible to imagine the functioning of society, the economy, business, the state and its citizens. The book describes the main models of extra-budgetary investment in transport, social, medical, IT and other projects. Such projects are the domain of big money, multi-path investment models and significant interests, and almost all such projects are based on direct investments from budgets of different levels or various forms of public-private partnerships (PPP). The material in the book is presented in understandable language, with numerous examples to help you master the most important information, and provides substantive advice on starting and implementing specific projects. They are the ones who can bring significant income to business, and the authority and respect of citizens.
