英文文献摘要：
Motivated by the logging ban in China and its future deregulation strategy, this paper theoretically examines the dynamic problem of forest management with spatial externality. I construct a theoretical, spatially-explicit model of a forest planner who maximizes timber profits from infinite timber rotation on all stands minus the costs of water runoff, and more importantly, asymmetric depending on the relative location of the stand. The model examines a spatial model of two stands, where the age of one stand affects the cost of the other stand, but asymmetrically. Using specific functional forms, I examine the properties of spatial and temporal substitutability between the two stands and the marginal value of staggering harvesting on one stand. The simulation results illustrate the efficiency gains of a spatial, subadditive model versus an aspatial, additive model.

在中国禁伐和未来放松管制战略的激励下，本文从理论上考察了具有空间外部性的森林经营动态问题。我构建了一个理论的、空间上明确的森林规划者模型，他通过对所有林分进行无限的木材轮作，减去水径流的成本，最大化木材的利润，更重要的是，不对称取决于林分的相对位置。该模型研究了两个看台的空间模型，其中一个看台的年龄影响到另一个看台的成本，但不对称。使用特定的功能形式，我检查了空间和时间的属性之间的替代性和边际价值的惊人收获在一个林分。仿真结果表明了空间次可加性模型与空域可加性模型的效率增益。
