چکیده
Article history: Received 19 June 2012 Received in revised form 8 March 2013 Accepted 16 August 2013 Available online xxxx This study conducts a 9-year longitudinal analysis on the effects of diversity of R&D sources, diversity of human capital, innovation infrastructure and academic knowledge on industrial performance. Here, I suggest there is an inverse U-shaped relationship between diversity of R&D sources and industrial performance. Industrial performance is also related to diversity of human capital in a curvilinear (inverted U-shaped) manner. Moreover, innovation infrastructure negatively moderates the effect of diversity of R&D sources on industrial performance, while academic knowledge also negatively moderates the effect of diversity of R&D human capital on industrial performance. The fixedand random-effects regressions are used to test the hypotheses in a panel data of 315 industry-year cases and the findings support our prediction. The results of this study can help reconciling contradictory findings fromprevious studies by demonstrating the potential impact of diversity on industrial performance. © 2013 Elsevier Inc.
