摘要： 民商合一体例下，我国《民法总则》吸收了大量的团体法思维。职务代理是团体自治对外发生效力的媒介制度，凭此媒介团体才能参与法律上之交易。为了充分发挥职务代理之功能，要构建起职务代理规则的适用体系。以契合其内在价值——团体自治和交易安全作为评判标准，选择“区别说”采有因性原则作为职务代理规则体系的基础理论，以此确定授权行为是职务代理权之权源。同时，通过论证职务代理类型化的正当性，以类型化思维结合基础理论解释《民法总则》第170条。“法人与非法人组织”应狭义解释为“私法人与非法人组织”；职务代理权应类型化为经理权与代办权，经理权的范围是经营团体业务所必要的一切行为，代办权范围是完成相应职务所必要的一切行为，且经理权与代办权范围的认定规则均具有习惯法之效力；本条第2款中“职权范围之限制”应等同于内部指示，该款为职务代理权滥用之规则。
