商品林外部性问题的内在化

Internalization of Externality Problem of Commercial Forest

根据林业生产中外部正效应、负效应现象的分析,论证商品林外部性正负效应转变的条件,认为商品林外部性的作用是一种隐形的影响。根据解决外部性问题的理论依据,结合商品林生产的实际情况,提出对营林作业给予差额补偿、对林道修建作业给予适当补偿、对优化伐区设计给予适当补偿、对延长轮伐期给予适当补偿、对木材生产给予减免税费、对荒山造林给予全额投资、对现有林分进行出资购买等商品林外部性问题内在化的措施建议。

The conditions of transforming between positive external effects and negative external effects of commercial forest were demonstrated on the basis of analyzing the phenomenon of the two effects in the producing process of forestry,and the works of externalities of commercial forests were treated as concealed influences.In the light of the theoretical foundation to solve the problem of externality,the suggestions concerning to the following measures about commercial forest internalization of externalities were presented combining with the real situation of production of commercial forest： make up for the silviculture work by margin;forest road construction,the design of optimization to cutting area and the work for prolonging the rotation period should be recouped appropriately;remit or reduce the tax of wood production;invest in afforestation on the barren mountain in full;purchase the current forest,etc.
