Research Impact

About this guide

This guide mainly introduces how bibliomentrics are used for informing research impact. You will learn how to use some useful tools for finding bibliometrics, journal rankings and different levels of impacts (author, article, journal, etc.).

The societal and economic impacts of your research activities are also significant in your research journey. In 2019, the Ministry of Business, Innovation and Employment introduced a new definition of research impact as “A change to the economy, society or environment, beyond contribution to knowledge and skills in research organisations” (p.9).

The following articles discussed the various ways to measure research impact:


Bibliometrics are indicators/metrics based on citation counts. These metrics are often used to analyse the impact of publications in a research field.

Use of Bibliometrics

  • Metrics, such as h-index, may help identify the impact of a researcher or a research output
  • Metrics may indicate research trends
  • Rankings and metrics may be used to inform decisions about journals to which you might submit your work for publication
  • Metrics may also help researchers decide which publication to be included in PBRF
  • Identify authors you might want to cite or collaborate with

Bibliometrics should always be interpreted cautiously. They are intended as a relative measure within a discipline, not as a numeric value to be taken in isolation.
