英文文献摘要：
This paper seeks to understand the mechanisms underlying the policies creating incentives for carbon sequestration. The key difficulty in designing carbon policies for forests is to take into account the ephemeral nature of carbon sequestration and to accurately track the carbon flow entering and exiting forests. Among a number of existing payment systems, carbon subsidy-tax system (CST) and carbon rental system are the only two systems which both consider nonpermanence and accurately track the forest carbon flow. In this paper, we derive the optimal conditions for harvests under various carbon policies and simulate the effects in a single region, multi age class timber market model. We find that carbon policy will encourage afforestation if it create additional revenue but the CST and carbon rental system are more effective than the others in extending rotation ages. Another finding is that costs of carbon rental system are much higher than that of CST system although they are efficiently equivalent.
制定森林碳政策的关键困难在于考虑到碳封存的短暂性，并准确跟踪进出森林的碳流量。在现有的支付体系中，只有碳补贴税(CST)和碳租赁制度既考虑了非永久性，又能准确地跟踪森林碳流量。在本文中，我们推导了不同碳政策下的最优收获条件，并模拟了单一地区、多年龄段木材市场模型的效果。我们发现，碳政策如果能创造额外的收入，就会鼓励植树造林，但CST和碳租赁制度在延长循环年限方面比其他制度更有效。另一个发现是碳租赁系统的成本远高于CST系统，尽管两者效率相当。
