Research on Adjustment between Forest Economic Policy and Forest Environmental Policy

这项研究的目的是澄清如何调整森林的经济用途与森林的环境用途。为此，笔者构建了“森林资源-森林经济-森林环境保护模型”（森林REE模型），该模型将森林资源模型、森林经济模型和森林环境保护模型相结合。我提出了森林经济利用和森林环境利用的调整政策。阐述了日本森林资源和林业的现状，指出以森林环境保护政策来调整森林经济政策是一个迫切需要解决的问题。这一问题在传统的森林经济学框架内是无法解决的。森林经济学需要一个新的范式。在论述了传统经济学和生态经济学的思想基础上，提出了基于生态经济学框架的新森林经济学。为了调整森林经济政策和森林环境保护政策，有必要构建基于生态经济学观点的森林REE模型。建立一个以系统动力学为基础的模型来处理与森林有关的活动的多尺度时间框架，即，一个长期的森林生产过程和一个短期的木材砍伐和加工生产过程。我们使用STELLA软件来构建系统动力学模型。本文讨论了利用STELLA构建森林REE模型时需要考虑的问题。构建了森林REE模型的STELLA模型，将森林资源模型、森林经济模型和森林环境保护模型整合在一起。我打算发表一些关于模拟模型和结果的文章，并讨论在不久的将来森林经济和森林环境的调整政策。

The aim of this research is to clarify how to adjust economic uses of forests with environmental uses of forests. To achieve this, I construct a "forest resources-forest economy-forest environmental conservation model (REE model of forest)", which integrate a forest resources model, a forest economy model, and a forest environmental conservation model. I propose an adjustment policy for economic uses of forests and environmental uses of forests.I clarify the current states of Japanese forest resources and forestry, and that it is an urgent problem to adjust an economic policy for forests with an environmental conservation policy of forests. It is impossible to solve this problem in the frame of traditional forest economics. A new paradigm is necessary for forest economics. After discussing the ideas of traditional economics and ecological economics, I argue new forest economics based on the frame of ecological economics. To adjust economic policies for forests and environmental conservation policies for forests, it is necessary to construct a REE model of forest based on the view of ecological economics. It is appropriate to construct a model based on system dynamics for handling multi-scales of time frame of activities concerning with forests, i.e., a long term production process for growing forests and a short term production process for cutting and processing of timbers.We use STELLA,the software for constructing system dynamics models. I discuss many issues to be considered during constructing a REE model of forest with STELLA.Constructing a STELLA model for a REE model of forest, I integrate three model, a forest resources model, a forest economy model, and a forest environmental conservation model.I intend to present articles concerning with simulation models and those results, and discussing adjustment policies for forest economy and forest environment in the near future.
