Large-scale overall asset transfer of timber forest becomes the main type of collective forest property transfer under the background of encouraging scale operation,calculating and applying forest harvest quota by independent forestry operators.Based on the characteristic of output and input of overall asset of timber forest under the control of forest harvest quote,this paper proposes the method for overall asset valuation of timber forest,and empirically calculates economic value of overall timber forest asset combining with the latest forest harvest quota policy.The result of this paper could be used for economic value appraisal of overall collective timber forest asset transfer,makes the valuation more reasonable and realistic.
