Middle-managers' innovative behaviours are considered an essential determinant of firm-level innovativeness. While prior research has traditionally focused on the contextual determinants of middle-managers' innovative work behaviour (IWB), research regarding individual-level determinants continues to remain scant. Particularly lacking is research which explores how middle-managers' ownership feelings influence their IWB. This study investigates whether middle-managers' affective commitment mediates the relationship between their psychological ownership and their IWB. Data are collected from 110 middle-managers – supervisor dyads in a large Malaysian IT organisation. Findings from this study contribute to enhancing our understanding of the individual-level determinants of middle-managers' IWB.
