An econometric analysis of the effect of collaboration on academic research productivity

Abstract

Previous studies on collaborative research emphasize industry-university collaboration conducted in a subset of academic disciplines associated with applied engineering. These studies focus on motivations, mechanisms, financial costs and financial benefits of collaborative research while paying little attention to the impact of collaborative research on academic productivity. The purpose of this paper is to attempt to compensate for some of these shortcomings. First, we present a survey which includes responses from academic researchers of all the scientific disciplines. Second, we take into account and compare the collaborative relationships between university researchers, between university researchers and industry, and between university researchers and other institutions, especially government agencies, local governments and organized interest groups. And third, we assess the impact of these collaborative activities on the academic productivity of the university researchers.

The results of this paper show that collaboration, whether it be undertaken with universities, industries or institutions, may indeed increase researchers' productivity. We find this to be true whether or not such relationships begin early in a researcher's career. We also find this to be true whether or not the collaborators have an intellectual symmetry. The effect of collaboration on productivity varies according to both the scientists' geographical closeness to their partners and on their field of research. It was found that collaboration between researchers and industry had significantly more impact on productivity than collaborations between researchers and their peers or researchers and other institutions. Scientists in humanities were found to produce less materials in collaboration than scientists in other fields. And, scientists involved in collaboration aimed mostly at producing patented and unpatented products, scientific instruments, software and artistic production were also found to produce less.

In sum, given that collaboration contributes to the increase of scientific productivity, government decision makers and university administrators ought to encourage researchers to forge collaborative relationships.
