Intellectual capital investment and firm performance of the Malaysian energy sector: a new perspective from a nonlinearity test. Energy Research Letters, 1(3). https://doi.org/10.46557/001c.1362226526433https://doi.org/10.46557/001c.13622https://hdl.handle.net/20.500.12519/826This study examines the association between intellectual capital investment and firm performance of the Malaysian energy sector. A non-linear relationship between intellectual capital investment and firm performance is established. At low levels of intellectual capital investment, increasing investments in intellectual capital improve firm performance. After a cut-off point, increments to intellectual capital investment reduce firm performance. © 2020, Asia-Pacific Applied Economics Association.
