In this article is considered the status and problems of timber industry of USSR during the period of perestroika (1985-1990), the period which became a kind of alternative to the Soviet economies development and, in particular, in timber industry. Special attention is paid to the development of forest machinery, as a factor that restrained the realization of potential of native scientists, engineers and producers. The result was realized in ever-increasing backlog of home machinery from abroad. This backlog caused further irreparable blow to the Onezjskji and Altaiskij factories in post-perestroika years, when loggers began to prefer foreign machines for logging operations, created mainly by firms from Scandinavian countries, which pursued an aggressing marketing policy.

Keywords: historical experience, forest sector, mechanical engineering, perestroika, innovative development.
