The purpose of this study is to assess the forestry management policy referring to CO2 balance and regional economy. For our purpose, we develop the integrated model that consists of the economic model and the thinning model. The thinning model is able to simulate the forest situation for 50 years under the forestry management policy at Nagara river basin where is divided into 6 areas such as Gujo, Mino, Seki, Gifu, Motosu and Hashima. At the result, the utilization of thinning timber instead of the fossil fuel is effective. Especially, the policy of using timber for construction gives the CO2 reduction and social net benefit those are maximized in all forestry management policies of using thinning timber.
