This paper introduces a tool for new service development in the context of emerging economies. For this aim, two-stage decision making model is applied for measuring the new service development-enhanced sustainable growth of emerging economies. At the first stage, bipolar q-ROF M-SWARA with golden cut is used for weighting the new service development process. At the second stage, bipolar q-ROF ELECTRE with golden cut is employed for illustrating the impact-relation map of sustainable growth determinants with respect to the new service development process for emerging economies. The novelties of this study are to construct a novel decision-making approach by using the bipolar q-ROFSs and golden cut and to figure out the influencing degrees and directions of sustainable growth determinants for emerging economies. It is also determined that testing has the highest significance while creating a new service for sustainable growth. Ranking results also demonstrate that qualified organizational teams and equipment is the most critical factor regarding innovative service process-based sustainable growth. It is necessary to adapt current technological developments to new products to be developed for sustainable growth. In this context, technological advances for these products should be followed carefully. In this process, it would be appropriate for companies to reach this goal by employing qualified personnel.
