本文研究了作为野生传粉者栖息地的复杂自然土地的恢复力的阴影值。我们捕捉作物生产中的授粉服务和周围自然土地的栖息地条件与生物经济模型之间的联系。我们的案例研究是荞麦，这是在日本中部的丘陵和山区生产，并在很大程度上依赖于不同的动物授粉服务。我们模拟机制的政权转移的生态系统组成的荞麦田和周围的自然土地的阈值估计模型。然后，我们发现，农田周围的森林，作为野生传粉者的栖息地，是一个生态阈值的决定因素，导致政权的转变。我们计算出一个单位荞麦田周围的森林栖息地提供的弹性阴影值为9，796美元，这意味着复杂的自然土地的弹性总价值相当于荞麦土地股票价格的一半。这一被忽视的价值为我们提供了关于生态系统可持续利用的有用见解，包括传粉媒介介导的农田和传粉媒介的栖息地。
This article investigates the shadow value of resilience in complex natural lands acting as wild pollinator habitats. We capture the linkage between pollination services in crop production and habitat conditions in the surrounding natural land with a bioeconomic model. Our case study is buckwheat, which is produced in the hilly and mountainous region of central Japan and is greatly dependent on diverse fauna for pollination services. We model the mechanism of regime shifts in ecosystems consisting of buckwheat fields and the surrounding natural land with a threshold estimation model. We then find that the forest around the crop fields, which serves as a habitat for wild pollinators, is a determinant of an ecological threshold that causes regime shifts. We calculate the shadow value of resilience provided by forest habitat around a unit of buckwheat field to be $9,796, implying that the total value of resilience in complex natural land amounts to half of the stock price of buckwheat land. This overlooked value gives us useful insights on the sustainable use of ecosystems, including both pollinator‐mediated crop fields and habitats for pollinators.
