地质灾害防治产品价值评估及其决策支撑

Value Evaluation and Decision Support of Geological Disaster Prevention and Control Products

经济价值评估是推进市场化地质灾害防治工作的关键,也是解决自然资源领域生态修复市场化程度不足的一项基础性工作。地质灾害防治本质上是公共安全品生产过程,它与一般生产企业的“投入、加工、产出”不同,其产品使用价值以“预测建议、移民搬迁和兴建防治工程”为体现,产品价值凝结于“前期预防”和“灾后治理”两个生产阶段,价值评估包含了“机会成本”和“历史成本”两项内容。地质灾害防治决策本身具有正效益,基于防治产品价值评估得出在价值最低值时做出单个生产决策,当边际收益与其他产业平均边际收益相等时可提出区域最优生产策略。

Economic value evaluation is crucial to promote the marketization of geological disaster prevention and control,and it is also a basic work to solve the lack of marketization of ecological restoration in the field of natural resources.The prevention and control of geological disaster is essentially the production process of public safety products.It is different from the"input,processing and output"of general productive enterprises.The use value of its products is embodied in"prediction and suggestion,resettlement and construction of prevention and control projects."The product value is condensed in the two production stages of"early prevention"and"post-disaster management,"value evaluation includes"opportunity cost"and"historical cost."The decision-making itself of geological disaster prevention and control has positive benefits.Based on the value evaluation of prevention and control products,we can make a single production decision when the value is the lowest,and we can put forward the regional optimal production strategy,when the marginal revenue is equal to the average marginal revenue of other industries.
