Abstract In this paper, we present a framework for the analysis of effects of language policies on the competition between languages. At the core of this framework is a language competition model that takes into account four pivotal factors for the evolution of the linguistic composition of a society: intergenerational language transmission, formal language education, adult language learning and migration. In contrast to the majority of models available in the literature, our model operates with parameters that can be estimated from empirical socio-linguistic data. It allows the reconstruction of past and simulate future dynamics. Language policies can be modeled as changes in model parameters. Therefore, projections derived from the model can be utilized to compare the effects of different policy options. We use Basque and Spanish within the Basque Autonomous Community in Spain to illustrate the application of the model.

语言竞争建模与语言政策评估

摘要 在本文中，我们提出了一个框架，用于分析语言政策对语言之间竞争的影响。该框架的核心是一个语言竞争模型，该模型考虑了社会语言构成演变的四个关键因素：代际语言传播、正规语言教育、成人语言学习和迁移。与文献中可用的大多数模型相比，我们的模型使用可以从经验社会语言数据中估计的参数运行。它允许重建过去并模拟未来的动态。语言策略可以建模为模型参数的变化。因此，可以利用从模型得出的预测来比较不同政策选项的效果。
