Penelitian ini bertujuan untuk menguji pengaruh karakteristik dari bank yang meliputi ukuran (size) bank, struktur kepemilikan bank, status bank publik, profitabilitas, dan umur bank terhadap kualitas penerapan corporate governance. Tingkat kualitas penerapan corporate governance diukur berdasarkan score yang dikembangkan oleh Mahdan (2010) dengan informasi yang diambil dari laporan corporate governance bank. Pengujian hipotesis dilakukan menggunakan model regresi berganda dengan sampel sebanyak 153 bank yang terdapat di Indonesia selama tahun 2008-2010. Hasil penelitian ini membuktikan bahwa ukuran (size) bank dan kepemilikan bank oleh pemerintah berpengaruh positif dan signifikan terhadap kualitas penerapan corporate governance. Namun kepemilikan bank oleh asing berpengaruh negatif dan signifikan terhadap kualitas penerapan corporate governance. Status bank publik memiliki pengaruh negatif yang lemah terhadap penerapan corporate governance. Sedangkan profitabilitas dan umur bank tidak berpengaruh terhadap kualitas penerapan corporate governance.
