Measuring the human capital of scientists in the principal investigator role

There is an emerging literature on scientists in the principal investigator (PI) role that identifies them as central and key actors in entrepreneurial ecosystems. PIs in leading large-scale public research programmes and teams require an array of skills and abilities to be effective in this role. The purpose of this paper is to propose a human capital (HC) measurement scale that can unearth their competencies at the micro level, since there is no specific measurement scale specifically for PIs.

The proposed model was reached relying on both qualitative and quantitative methodologies, to then apply exploratory factor analysis (EPT) and confirmatory factor analysis (AFC) to verify its suitability, as well as its internal consistency and reliability using appropriate indices.

The proposed model is composed of six PI's HC factors, such as research knowledge, open-mind research ability, research perform ability, stoic research skill, innovation skill and critical skill.

In proposing this, this paper advances micro-level understanding of the competencies that PIs require to be effective in the role, and answers the call for deeper research on these crucial actors. Shedding light on this issue is beneficial for not only the administrators of the universities, the research centres or the funding agencies to obtain further essential information in selecting the best-qualified person, but also to self-evaluate their skills, abilities and knowledge so that they can direct their efforts towards improving the weak aspects of their HC. Furthermore, it can be an additional useful criterion for defining the career plans of PIs or their promotion policies.
