Abstract
This study used secondary data analysis to observe the relationship among knowledge source heterogeneity, knowledge flow, innovation and financial performance. We focused on three dimensions of knowledge source heterogeneity: geographical dissimilarity, technological dissimilarity, and language difference and hypothesized that knowledge source heterogeneity decrease knowledge flow because the extent of differences between the knowledge source and the recipient might increase barriers and hence make knowledge hardly to flow. On the other hand, the knowledge source heterogeneity might bring broader and nonredundant ideas or expertise for firms to facilitate innovation performance and thus we hypothesized that knowledge source heterogeneity has positive moderation effects on the relationship between knowledge flow and innovation. Furthermore, we also hypothesized that innovation increases financial performance because firms could have better development of products or service processes to benefit its growth or profitability.
Hypotheses were tested by using patent citation data from USPTO of 408 firms in semiconductor industry in the period from 1987 to 2007. We used negative binomial regression model to examine the effect of knowledge source heterogeneity on the knowledge flow. The results indicated that technological dissimilarity and language difference have negative impact on the knowledge flow, while geographical dissimilarity has no significantly effects on the knowledge flow. Besides, we examined moderation effects of knowledge source heterogeneity on the relationship between knowledge flow and innovation by using negative binomial regression model. The results showed that technological dissimilarity positively moderates the effect of knowledge flow on innovation, while geographical dissimilarity and language difference have no positive and significant moderation effects on the relationship between knowledge flow and innovation. In this study, we found that although knowledge source heterogeneity increases barriers between firms and influenced the ease of knowledge flow, it has positive moderation effects that makes knowledge flow lead to higher innovation performance.
