Abstract
As indicated by the WBCSD, the triple bottom
line should be the goal of an enterprise’s sustainable operation. PSS and past
literature related to sustainability have mostly discussed related theory or
conducted empirical research. Many recent studies have integrated the two
aspects to describe sustainable business models, but they have mostly been
based on case studies. Therefore, this research integrated qualitative and
quantitative viewpoints to construct sustainable product-service business
models and it was carried out in three phases. Phase1 referred to conceptualization,
in which past literature and focus group interviews were combined to construct
the preliminary items and the questionnaire. Phase2 referred to measurement,
in which the reliability and validity of the various questionnaire dimensions
were verified. Phase3 referred to verification, which was aimed at the integrative framework
of S-PSS models. AHP was used to analyze
the relative importance and managerial implications of each dimension. In the
main dimensions of sustainable product-service business models, the dimension
of scientific and technological sustainable development is more crucial than
the dimensions of product-service sustainable development, social sustainable
development and organizational sustainable development. In the minor
dimensions, creating value from waste, new service delivery, delivering
functionality rather than ownership, and developing scale up solutions are more
crucial.
