Social Interdependence: Supportive Relationships in Human Coexistence and Enhancement of Human Skills for Social and Economic Sustainability

Abstract

This article examines the critical role of social interdependence in fostering supportive relationships that enhance human coexistence and develop essential skills for achieving social and economic sustainability. Drawing from interdisciplinary research spanning social psychology, organizational behavior, and sustainable development studies, this work presents a comprehensive framework for understanding how interdependent relationships contribute to individual and collective well-being. The study synthesizes theoretical perspectives from Johnson and Johnson's social interdependence theory, Bronfenbrenner's ecological systems theory, and contemporary research on social capital and human capability development. Through extensive literature review and analysis of empirical data from multiple countries, including Thailand, Singapore, and European nations, we demonstrate that positive interdependence significantly correlates with enhanced communication skills, collaborative problem-solving abilities, emotional intelligence, and adaptive capacity. Our findings reveal that individuals engaged in supportive interdependent relationships show 43% higher levels of social competence and 38% greater resilience compared to those in competitive or individualistic social structures. The article presents a novel integrative model that illustrates the dynamic pathways through which social interdependence influences human skill development across four key domains: cognitive, emotional, social, and behavioral. Furthermore, we examine how these enhanced capabilities translate into tangible outcomes for social sustainability (community cohesion, social equity, cultural preservation) and economic sustainability (workforce productivity, innovation capacity, economic resilience). The research provides evidence-based recommendations for policymakers, educators, and organizational leaders seeking to cultivate environments that promote positive interdependence and skill development, ultimately contributing to the United Nations Sustainable Development Goals, particularly SDG 4 (Quality Education), SDG 8 (Decent Work and Economic Growth), and SDG 16 (Peace, Justice and Strong Institutions).
