From Cultural Differences to Consumption Equity: A Study on Multilevel Consumer Inclusive Marketing Strategies and Their Psychological Mechanisms

In today's globalized marketplace, cultural differences among consumers pose significant challenges to achieving consumption equity. While inclusive marketing has emerged as a promising approach to address diverse consumer needs, the psychological mechanisms through which cultural differences affect consumer responses and the multilevel strategies firms can employ to promote consumption equity remain underexplored. This study investigates how cross-cultural consumer psychological characteristics, including cultural trust, identity recognition, and in-group or out-group bias, influence consumption equity perceptions and examines the effectiveness of multilevel inclusive marketing strategies in bridging these cultural divides. Employing a mixed-methods approach, the study analyzes publicly available consumer behavior datasets from multinational retail platforms and existing cross-cultural survey databases. Three case studies are conducted: cultural trust and brand loyalty in cross-border e-commerce, ethnic identity recognition and consumer ethnocentrism in multicultural markets, and cultural bias and algorithmic recommendation fairness on digital platforms. The findings reveal that cultural differences shape consumer responses through distinct psychological pathways, with trust serving as a critical mediator between cultural distance and consumption equity perceptions. Multilevel inclusive marketing strategies, including product-level customization, communication-level cultural adaptation, and platform-level algorithmic fairness, demonstrate varying effectiveness across cultural contexts. This study contributes to inclusive marketing literature by illuminating the psychological mechanisms underlying cross-cultural consumer behavior and provides actionable insights for marketers seeking to design culturally sensitive strategies that advance consumption equity.
