Inconclusive innovation "returns": a meta-analysis of research on innovation in new product development

Abstract

This research on studies that have empirically examined the construct innovation provides a meta-analysis of the marketing, management, and new product literatures. The study extends previous meta-analytic works by drawing on 70 independent samples from 64 studies (published from 1970 to 2006) with a total sample size of 12,921. The overall objective is to propose a synthesized model that includes technological turbulence, market turbulence, customer orientation, competitor orientation, organizational structure, innovation, and new product performance. Six baseline hypotheses were developed and tested. The goal is not only to derive empirical generalizations from these literatures but also to investigate sources of inconsistencies in the findings. Four substantive and two methodological artifacts were tested to determine whether they moderate model relationships (i.e., whether the effect sizes differ for any of the six baseline hypotheses). The potential moderators were project versus program level of analysis, the nature of change required by the innovation, service versus product, country of the data's origin, continuous versus categorical measurement, and the number of scales used. From a theoretical perspective, the results corroborated the resource-based view framework regarding the determinants and the performance outcome of innovation. New product performance (the performance outcome) is a direct consequence of innovation, and this effect is stronger when the data are collected from Western countries. This relationship holds regardless of whether the level of analysis is the new product program versus project or whether the innovation is a product or a service, a robust result relevant to researchers and managers alike. As for the determinants of innovation, the results were as follows. While market turbulence is overall not a direct antecedent to innovation, technological turbulence is overall positively related (especially when market discontinuities are considered or when the data are collected from Asian countries). Customer orientation encourages new product innovation overall, but especially at the program (as opposed to project) level in Western countries. The effect of competitor orientation is also positive. The results for either orientation construct or either turbulence construct held whether the level of analysis was project versus program or whether services versus products were examined. However, the relationship of mechanistic organizational structures to innovation, although positive in the overall sample, did vary by product (positive) versus service (negative).
