Objective: This paper aims to identify research trends on the influence of leadership style in the era of industrial revolution 4.0 on innovation work behaviour globally. Design/Methodology/Approach: The method used in this study is qualitative research with bibliometric analysis. The author used the Scopus database to collect empirical evidence with the keywords "innovative work behaviour" and "leadership". The data found were 189 documents obtained and analysed from 2019-2023. This dataset was converted to RIS format and imported for bibliometric analysis using VOSviwer. The analysis included publication distribution year, country, keywords and authors. Findings: The findings of this study are the need for elaboration on the influence of leadership styles in the era of the industrial revolution 4.0 on innovative work behaviour. Future research topics on leadership styles that provide great opportunities for further study in the era of the industrial revolution 4.0 are authentic leadership, digital leadership, self-leadership, and leader-member exchange. Research limitations/implications: This study only uses data from the Scopus database. Originality/Value: This paper reveals research trends on leadership style and innovation work behaviour over the past 5 years (2019-2023). The results may help researchers or scholars to understand further research opportunities with the topic. This article may also provide an alternative approach to conducting literature reviews with computer-aided analysis programmes.
