宏观经济模型中的生态系统总产值

对经济健康的更全面评估

A more comprehensive assessment of economic health

联合研究中心是欧盟委员会的科学和知识服务机构,旨在为欧洲决策过程提供基于证据的科学支持,该中心最近发布了 “宏观经济模型中的生态系统生产总值”。该报告通过将生态系统服务的价值纳入宏观经济框架,引入了一种经济分析的变革性方法。传统的经济指标,如国内生产总值(GDP),在涵盖经济贡献的全范围方面一直存在不足,特别是那些由自然生态系统提供的贡献。本报告主张采用生态系统生产总值(GEP作为 GDP 的补充指标,旨在提供一个更全面的经济健康评估,其中包括从生态系统中带来的益处。

The Joint Research Centre, the European Commission’s science and knowledge service which aims to provide evidence-based scientific support to the European policymaking process, recently released the “Gross Ecosystem Product in Macroeconomic Modelling”. The report introduces a transformative approach to economic analysis by integrating the value of ecosystem services into macroeconomic frameworks. Traditional economic indicators such as Gross Domestic Product (GDP) have been inadequate in capturing the full range of economic contributions, particularly those provided by natural ecosystems. This report advocates for the adoption of the Gross Ecosystem Product (GEP) as a complementary metric to GDP, aiming to offer a more comprehensive assessment of economic health that includes the benefits derived from ecosystems.

生态系统生产总值

Gross Ecosystem Product (GEP)

该报告的主要创新在于创建了 GEP 指标,该指标量化了生态系统服务的经济价值。与衡量人类活动所生产的商品和服务货币价值的 GDP 不同,GEP 涵盖了自然生态系统提供的益处,如空气净化、水过滤、碳封存和生物多样性。通过将 GEP 与 GDP 相结合,政策制定者可以获得包含人力和自然资本的经济表现的整体视图。

The report’s primary innovation is the creation of the GEP metric, which quantifies the economic value of ecosystem services. Unlike GDP, which measures the monetary value of goods and services produced by human activity, GEP accounts for the benefits provided by natural ecosystems such as air purification, water filtration, carbon sequestration, and biodiversity. By integrating GEP with GDP, policymakers can gain a holistic view of economic performance that encompasses both human and natural capital.
