Global fertility decline has become a major demographic transformation shaping contemporary societies. While prior research has focused on its implications for labor markets, aging, and welfare systems, its effects on consumption structures remain fragmented. This article develops a conceptual framework explaining how fertility decline reshapes market demand through household-level mechanisms. Drawing on demographic transition theory, household economics, and consumer behavior, the study introduces the concept of Demographic Demand Shifts, referring to structural changes in consumption patterns driven by demographic transformation. The framework proposes a multi-stage process in which declining fertility leads to smaller households, delayed parenthood, and rising childlessness, thereby transforming household structures. These changes trigger the reallocation of financial and temporal resources, shifting consumption toward adult-centered, experience-oriented, and longevity-related goods and services. Over time, these micro-level adjustments aggregate into broader transformations in market demand, increasing the prominence of service-based consumption. The framework also highlights the moderating roles of welfare institutions and digital economy infrastructure. By clarifying the mechanisms linking demographic change to consumption transformation, this study provides a theoretical foundation for future research on evolving consumption systems.
