REGIONS OF THE COUNTRY IN THE «SHADOW» OF RUSSIAN AVIATION INDUSTRY
Аннотация
Федеративное устройство России придает регионам страны особую значимость в ее социально- экономическом развитии. Это предполагает острую необходимость укрепления всей системы межрегиональ- ных связей, где важное место принадлежит транспорту, в том числе авиации, которая для многих наших территорий выступает единственным средством перемещения грузов и пассажиров. Кризис отечественного авиапрома здесь сказывается особенно болезненно, что и требует принятия на самых верхних эшелонах нашей власти эффективных мер по радикальной корректировке стратегии развития отечественного авиастроения, используя механизм государственно-частного партнерства.
