چکیده
This research was conducted in the west forest of Guilan, northern Iran. Data from various harvesting methods for 20 years were collected. Results showed that, productivity rate of round wood, pulp wood and fuel wood has had an upward trend, while rate of traditional products (lumber, sawn wood, charcoal, etc.) has had a downward trend. Production cost has been investigated in this research. The results showed that, the main cost is the opportunity cost. Due to the disability of competition between the domestic wood price with the imported wood price, domestic wood industries will face serious investment difficulty in the future.
