Economic assessment of forest management, including tending, thinning, and clear-cut, is essential to maximize social benefits. This study investigated the economic viability of forest management in the Republic of Korea at national scale (2017–2100) by quantitative approaches. The changes in benefits of four ecosystem services (timber production, CO₂ sequestration, water yield enhancement, and disaster risk reduction) and management cost were quantified by a combination of ecosystem models and national data. The forest management scenarios, varying interval of clear-cut (40–80 years) and area of management (0.9–3.0 million ha), were applied. Net present value (NPV) was estimated as an indicator of economic viability of forest management. The NPV increased with decreasing clear-cut interval and increasing management area (7.7–50.8 billion $). Even the benefit-cost ratio (BCR), the ratio of total benefit to total cost in terms of present value, was 1.9 under the most intensive forest management scenario. This result implied that intensive forest management is economically viable in the long-term. The sensitive analysis showed that economic viability would be maintained in spite of change in macroeconomic factor. These methodological approach and result would contribute to implementing effective forest management, which can maximize social benefits.

对森林经营的经济评估，包括抚育，间伐和砍伐，对于最大化社会效益至关重要。这项研究通过定量方法调查了大韩民国国家范围（2017–2100）森林管理的经济可行性。四种生态系统服务（木材生产，CO ₂固碳，提高水产量和减少灾害风险）和管理成本是通过结合生态系统模型和国家数据进行量化的。应用了森林管理方案，不同的明确采伐间隔（40-80年）和经营范围（0.9-300万公顷）。估计净现值（NPV）可作为森林经营经济可行性的指标。净现值随着清除间隔的缩短和管理区域的增加而增加（77-50.8十亿美元）。在森林经营最密集的情况下，即使是效益成本比（BCR），即总收益与总成本的现值之比，也为1.9。该结果表明，从长远来看，集约化森林经营在经济上是可行的。敏感的分析表明，尽管宏观经济因素发生了变化，但经济生存能力仍将保持。这些方法论方法和结果将有助于实施有效的森林管理，从而最大程度地提高社会效益。
