An investigation into the effects of product design on incremental and radical innovations from the perspective of consumer perceptions: Evidence from China

By integrating research on product design with ideas from marketing and consumer perceptions, this paper formulates a set of coherent hypotheses about the effects of tripartite design dimensions on consumer perceptions and responses. We conduct two surveys on incremental and radical technology innovations, respectively, and accordingly get two different samples to test the hypotheses. Empirical results reveal that the effects of aesthetic and functional dimensions on consumer purchase intention and word of mouth vary across two types of innovations. Specifically, for incrementally innovative products, aesthetic and functional dimensions influence consumer purchase intention and word of mouth, both directly and indirectly, through the mediation of consumer perceived quality. By contrast, for radically innovative products, the effects of aesthetic and functional dimensions on purchase intention and word of mouth are totally mediated by perceived quality. Additionally, the effects of symbolic dimension on consumer perceptions and responses achieve consistency across radical and incremental technology innovations. That is, the higher the level of symbolic dimension, the stronger purchase intention and the better word of mouth there will be, whereas the direct influence of symbolic dimension on perceived quality is not significant in either innovation category.
