This study aims to update the supply-demand model of wood products (FOSMO-2013) and to forecast mid and long run supply and demand for each products. The subjects of the study include sawnwood, plywood, particle board, fiberboard(MDF), and pulp. The updated partial equilibrium model is composed of supply function, import demand function, demand function, price relation function. The long run outlooks of world prices of wood and wood products are imported from the results of Buongiorno(2012). This study also adopt Buongiorno's scenarios, which includes three scenarios of IPCC(A1B, A2, B2) and the other one with assumption of increasing fuelwood consumption of A1B scenario. The result says that the domestic productions of wood products are expecting to decrease while the imports of them increase even there are some differences among the products as well as scenarios.

This study is aimed at developing a supply-demand model of wood products, and outlook for midterm and long-term supply and demand for each products. The main wood products include sawnwood, plywood, particle board, fiberboard (MDF), and pulp. The partial equilibrium model is composed of supply function, import demand function, demand function, price relation function. With given parameters the outlook for year 2050 says that sawnwood, plywood, and fiberboard for domestic productions and imports are decreased. This may result from the increase of log prices from the inside and outside of the country because of the propensity for environment protection and the resource nationalism. On the other hand the supply of particle board and pulp will increase because they are made from wasted wood and chips.
