ABSTRAKPenelitian ini bertujuan untuk menginvestigasi pengaruh unrelated diversification terhadap kinerja perusahaan dan menginvestigasi peran keberagaman direksi terhadap pengaruh unrelated diversification terhadap kinerja perusahaan. Objek penelitian yang dilakukan terdiri dari seluruh perusahaan non-keuangan yang terdaftar di BEI pada tahun 2013-2015 dengan jumlah sampel 709. Unrelated Diversification diukur menggunakan entropy index, dan keberagaman direksi menggunakan Blau Heterogeneity Index. Hasil penelitian menunjukkan bahwa unrelated diversification tidak mempengaruhi kinerja perusahaan. Namun demikian keberagaman tenure direksi terbukti memperkuat dampak negatif unrelated diversification terhadap kinerja perusahaan sedangkan keberagaman latar belakang fungsional memperlemah dampak negatif unrelated diversification terhadap kinerja perusahaan.

The research object consisted of all non financial companies listed on BEI in 2013 2015 and resulted in 709 samples. Unrelated Diversification is measured using the entropy index, and the diversity of directors using Blau Heterogeneity Index.
