This book provides the reader with a fresh perspective on the use of theory in the body of research centred on social impacts of tourism. Theory is advanced in three primary forms within this volume. Some apply novel frameworks (e.g., theory of interaction ritual; degrowth paradigm; and mere exposure theory) to contexts involving destination residents. Others consider various uniquely complemented theoretical frameworks (e.g., social exchange theory and affect theory of exchange; Weber's theory of rationality and Foucauldian constructs; and emotional solidarity and cognitive appraisal theory). Still others develop theoretical frameworks (e.g., influence of presumed influence model, elaboration likelihood model, and social exchange theory; tourist-resident social contact; quality of life; and socio-ecological systems theory and chaos theory) for others to potentially consider and test. The chapters in this edited volume contribute to the evolving advancement of theoretical applications within the research area of social impacts of tourism.This book will be of great interest to all upper-level students and researchers in tourism, planning and related fields. The chapters in this volume were originally published as a special issue of Journal of Sustainable Tourism.
