Pluricentrism presupposes the existence of several territories under the influence of different linguistic usage norms. From a glottopolitical perspective, focused on the conflicts and tensions involved in the control and understanding of the language as a social object, the normative dynamics of Spanish and Portuguese are compared, paying attention to the differences in the colonizing processes undertaken by Spain and Portugal and the ways in which the international spaces of both languages were constituted. According to its specific characteristics, the international space of Spanish has been defined in this work as a “mixed pluricentrism” and that of Portuguese as an “unequal bicentrism.” The differences in the constitution of linguistic markets in both languages allow us to understand their conflicting social representations, such as “united” or “divided” languages, as well as political and ideological initiatives to build a notion of an international language. The political tensions over the establishment of the standard norm also depend on the differences in the participation of normative agents, linked to academies of the language in the case of Spanish, but not in the case of Portuguese, and to the establishment of diverse negotiating forums.

多中心论以在不同语言使用规范的影响下存在多个领土为前提。从全球政治角度，着眼于控制和理解作为一种社会对象的语言所涉及的冲突和紧张局势，比较了西班牙语和葡萄牙语的规范动力，并注意西班牙和葡萄牙在殖民化过程中的差异。两种语言的国际空间的构成方式。根据其特定特征，在此工作中，西班牙的国际空间被定义为“混合的多中心主义”，而葡萄牙的国际空间被定义为“不平等的双中心主义”。两种语言在语言市场的构成上的差异，使我们能够理解它们相互矛盾的社会表现形式，例如“统一”或“分开”的语言，以及建立国际语言概念的政治和意识形态举措。关于建立标准规范的政治紧张局势还取决于规范代理人参与的差异（在西班牙语中与语言学院有关，在葡萄牙语中与语言学院无关，以及建立各种谈判论坛） 。
