Consumer’s perceptions toward longer product use and their influence on product lifespan
Yamamoto, Haruhisa; Murakami, Shinsuke
Product lifespan extension is effective for reducing material throughput and thus turning our
resource use to a more sustainable style. It is crucial not only to design a more durable product but to
encourage consumers to actually use their products longer. Therefore, the understanding of the
influences of consumer's psychological attributes upon product lifespan is required. This paper
attempted to quantitatively assess the influences of consumer's perceptions toward longer product use
to the actual and expected lifespan through a questionnaire survey. It was shown that intention and
attitude toward longer product use both had significant influences of extending both the actual and
intended lifespan. However, the intended lifespan was influenced also by several other perceptions,
while the actual lifespan was influenced by none of the others. In addition, consumers who had a
stronger intention or attitude were more likely to experience a larger gap between the intended and
actual lifespan. The paper concludes with an implication to researchers and policymakers that work on
product lifespan.
