英文文献：On the Productive Value of Biodiversity-关于生物多样性的生产价值
英文文献作者：Chavas, Jean-Paul
英文文献摘要：
The paper investigates the value of biodiversity as it relates to the productive value of services provided by an ecosystem. It analyzes how the value of an ecosystem can be "greater than the sum of its parts." First, it proposes a general measure of the value of biodiversity. Second, this measure is decomposed into four components, reflecting the role of complementarity, scale, convexity, and catalytic effects. This provides new information on the sources and determinants of biodiversity value. Third, the paper examines the role of uncertainty. In this context, the role of risk and of downside-risk exposure and their effects on the value of biodiversity are explored. This provides useful insights on how management and policy decisions can affect the value of biodiversity.
本文研究了生物多样性的价值，因为它与生态系统提供的服务的生产价值有关。它分析了生态系统的价值如何“大于其各部分的总和”。首先，它提出了生物多样性价值的一般衡量标准。其次，将该措施分解为四个要素，体现互补、规模、凸性和催化作用。这为生物多样性价值的来源和决定因素提供了新的信息。第三，本文考察了不确定性的作用。在这方面，探讨了风险和下行风险暴露的作用及其对生物多样性价值的影响。这为管理和政策决定如何影响生物多样性的价值提供了有用的见解。
