Куда уходят грузы? Анализ речных перевозок на Северной Двине

В докладе анализируются причины падения объемов судоходства не только в бассейне реки Северная Двина, но и в других лесных портах и географических зонах, делается общий вывод о причинах исчезновения лесных грузов на реке, о происходящих необратимых системных явлениях в этой отрасли: железнодорожной конкуренции, контейнеризации, укрупнении торговых партий, появления новой продукции и новых маршрутов.
