Increased emphasis on the natural capital approach in the UK has led to greater demand for methods that link economic sectors with elements of natural capital, and that can provide evidence for sustainable management of the environment. However, factors describing the supply of benefits, and their links with economic sectors, are not well defined.

This study develops a novel framework that investigates how the combination of different forms of capital (natural, financial, social, manufactured or human) provide a potential supply of benefits, and how changes in quality or extent of natural capital affects supply. Factors affecting the delivery of benefits are analysed, and indicators for each factor are selected. Indicators are ranked and weighted, and benefit supply is represented as a novel, composite index. The composite supply index is then linked as an input to a related economic sector.

This framework is applied for the first time to four benefits from the marine environment in the UK: seafood, offshore wind energy, wildlife watching and water sports. The approach is compatible with national accounts, natural capital accounts, and established ecosystem service classifications. This study shows how linking economic sectors with benefits can provide new evidence in support of marine management.

英国对自然资本方法的日益重视导致对将经济部门与自然资本要素联系起来的方法的需求增加，这些方法可以为环境的可持续管理提供证据。然而，描述福利供应的因素及其与经济部门的联系并没有明确定义。

本研究开发了一个新颖的框架，调查不同形式的资本（自然、金融、社会、制造或人力）的组合如何提供潜在的利益供应，以及自然资本的质量或范围的变化如何影响供应。分析影响福利交付的因素，并为每个因素选择指标。指标被排序和加权，福利供应被表示为一个新颖的综合指数。然后将综合供应指数作为相关经济部门的输入链接起来。

该框架首次应用于英国海洋环境的四大好处：海鲜、海上风能、野生动物观赏和水上运动。该方法与国民账户、自然资本账户和既定的生态系统服务分类兼容。这项研究表明，将经济部门与利益联系起来可以为支持海洋管理提供新的证据。
