An Integration of Research Findings of Effects of Firm Size and Market Competition on Product and Process Innovations

Product and process innovations have been studied as distinct phenomena whose introduction is influenced differently by firm and market conditions. This study reviews and quantitatively integrates the findings of the empirical studies of the associations of firm size and market competition with product and process innovations. The accumulation of research results and subgroup analyses of construct measurement do not provide evidence of substantial differences in the strength of the influence of size or competition on the two innovation types. Implications of the results for future research on innovation types as distinct or integrative phenomena are discussed.
