摘要：

《民法典》第388条第1款明确扩大了担保合同的适用范围，将功能上起担保作用的交易形式纳入其中，为形式主义立法模式之下的金融担保创新留下了空间。更为重要的是，通过与统一的动产和权利担保登记公示制度的结合，《民法典》第388条第1款为担保领域内物权法定的缓和提供了解释基础，进而为我国担保制度在形式主义基础上植入了功能主义的合理元素，这为统一的顺位规则奠定了基础，为担保权利的规范互用提供了契机。

Abstract:

The Article 388(1)of Civil Code explicitly expands the scope of application of security contract，including the transaction forms with security function，which leaves room for the innovation of financial security under the formalism legislative model.More importantly，through combining with the unified secured transactions registration publicity system，the Article 388(1)of Civil Code provides the explanation basis for the relaxation of the numerus clausus principle in the field of secured transactions，and then implants the reasonable elements of functionalism on the basis of the formalism of secured transactions，which lays the groundwork for unified priority rules and provides the opportunity to guarantee the interoperability of security rights.
