The concept of equivalence is present in various forms in the Solvency II framework, the EU prudential regulatory framework for insurance and reinsurance. While equivalence in Solvency II does not grant, or should not be equated to, market access for market participants that make use of the equivalence instruments within Solvency II, equivalence plays an important role in insurance, in particular in the solvency capital calculation at group level, in group supervision and for the recognition of reinsurance under Solvency II. The conclusion can be drawn that equivalence is an essential building block of the current framework. The application of equivalence in the framework and in practice is discussed in this contribution, and while the application might be complex, it is indispensable. At the same time, other mechanisms, either within the Solvency II framework or more broadly at international level, influence the current state and might affect the evolution of equivalence going forward. While, inherently, there is a political component to equivalence as well, the instruments remain firmly based in (detailed) Solvency II rules and are applied accordingly in practice.

等效概念以多种形式存在于偿付能力II框架（欧盟保险和再保险审慎监管框架）中。虽然偿付能力 II 中的等效性并不向使用偿付能力 II 中的等效工具的市场参与者授予市场准入，但等效性在保险中发挥着重要作用，特别是在集团层面的偿付能力资本计算中，在集团监管中以及根据偿付能力II认可再保险。可以得出的结论是，等效性是当前框架的重要组成部分。本文讨论了等效性在框架和实践中的应用，虽然应用可能很复杂，但它是必不可少的。与此同时，偿付能力监管体系 II 框架内或更广泛的国际层面的其他机制也会影响当前状态，并可能影响未来等效性的演变。虽然从本质上讲，对等也存在政治成分，但这些工具仍然牢固地以（详细的）偿付能力 II 规则为基础，并在实践中相应应用。
