Abstract

Amid the growing “complexity turn” in language research paradigms, second language (L2) interactional competence—characterized by its dynamicity, contextual dependence, and multidimensional coordination—has emerged as a central focus in fields such as second language acquisition, pragmatics, and language assessment. While existing studies have yielded valuable insights into language resource allocation, communicative strategy use, and competence evaluation, theoretical frameworks remain underdeveloped, particularly in explaining the nonlinear trajectories, system coupling mechanisms, and individual variation pathways that characterize the development of interactional competence. Drawing on Complex Dynamic Systems Theory (CDST) and integrating perspectives from language ecology and social interaction theory, this study proposes a three-tiered model of L2 interactional competence development encompassing the macro, meso, and micro levels. The model articulates key variables, including cultural ideologies, language policies, social networks, communicative settings, linguistic behaviors, and individual attributes, etc., and explores their dynamic interplay across intertwined spatial and temporal dimensions. By advancing this system-based model, the study seeks to move beyond static and linear explanatory paradigms, offering a more comprehensive understanding of the emergent and evolving nature of L2 interactional competence. It also expects to provide theoretical support and practical implications for instructional design, competence assessment, and individualized learning trajectory modeling.
