Considering the valuation of forest stands based on revenue from wood sales, concession policy (such as carbon subsidies) and associated costs, the paper focuses on the stochastic control model to study the forest asset dynamic management. The key contribution is to find the optimal dynamic strategy about harvesting quantity in the continual and multiple periods in conditions of stochastic commodity price and timber growth by using portfolio approach. Finally, an analytical optimal strategy is obtained to analyze the quantification relations through which some important conclusions about the optimal forest management can be drawn.
Applying the portfolio and stochastic control theory, the paper comparatively considers tow carbon subsidies schemes: Renting and Purchasing, and focuses on the rental scheme to present a stochastic control model and obtain an analytical optimal dynamic strategy about harvesting quantity in conditions of stochastic commodity price and timber growth. Through contrasts, the conclusion shows that government will pay less under the rental scheme than under the purchasing scheme for the same negative effect on harvesting quantity.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
