内容提要 《民法总则》第9条的绿色原则并非仅有环境保护一端，而是有环境保护与节约资源双重面向。环境保护诚然是绿色原则的重点，但无论是在公法层面还是在私法层面，环保意义上的绿色原则均难以有所作为，诸多应用舛误重重。节约资源有片面和全面之分，片面的节约资源在目前实践中颇为常见，但均为绿色原则之误用;全面的节约资源等同于社会成本最小化或社会财富最大化，即法经济学，而这才是绿色原则的未来。
关键词 节约资源 环境保护 社会成本最小化 民法经济分析 民法基本原则
Abstract: As a green principle, article 9 of the General Provisions of the Chinese Civil Law aims not only to protect the environment, but also to save resources. Although environmental protection is a crucial part of the green principle, the principle in this sense can rarely be applied in the context of the public law or the private law. On saving resources there are the one-sided interpretation and the comprehensive one. The one-sided interpretation is quite common in practice, but erroneous. The comprehensive interpretation is an equivalent of minimizing social cost or maximizing social wealth and leads to the Law and Economics, which must be the future of the green principle.
