Penelitian ini bertujuan untuk menginvestigasi dan memberikan bukti empiris mengenai hubungan antara mekanisme corporate governance dengan kualitas laba. Penelitian ini juga menginvestigasi hubungan kualitas laba dengan nilai perusahaan. Selanjutnya penelitian ini menginvestigasi hubungan mekanisme corporate governance dengan nilai perusahaan. Akhirnya, penelitian ini juga menginvestigasi apakah kualitas laba berperan sebagai variabel pemediasi (variable intervening) pada hubungan antara mekanisme corporate governance dan nilai perusahaan. Untuk menguji hipotesis alternatif, penelitian ini menggunakan perusahaanperusahaan manufaktur yang terdaftar di Bursa Efek Jakarta (BEJ) yang mengumumkan laporan keuangan selama tahun 2000-2004. Pengumpulan data dilakukan dengan metode purposive sampling. Jumlah perusahaan yang dijadikan sampel adalah 74 perusahaan dengan total observasi sebesar 197. Hasil penelitian menunjukkan bahwa mekanisme corporate governance berpengaruh terhadap kualitas laba. Proksi kualitas laba yang dikemukakan oleh Sloan (1996), Chan et al (2001) dan Warfield et al (1995) adalah discretionary accruals. Adapun mekanisme corporate governance yang berpengaruh terhadap kualitas laba adalah: (1) Kepemilikan manajerial secara positif dan signifikan secara statistik berpengaruh terhadap kualitas laba, (2) Proporsi dewan komisaris secara negatif dan signifikan secara statistik berpengaruh terhadap kualitas laba, (3) Keberadaaan komite audit secara positif dan signifikan secara statistik mempengaruhi kualitas laba. Hasil penelitian juga menunjukkan bahwa kualitas laba secara positif dan signifikan secara statistik mempengaruhi nilai perusahaan. Selanjutnya, hasil penelitian menunjukkan bahwa mekanisme corporate governance berpengaruh terhadap nilai perusahaan. Akhirnya, hasil penelitian ini menunjukkan bahwa kualitas laba bukan sebagai variabel pemediasi (variable intervening) pada hubungan antara mekanisme corporate governance dan nilai perusahaan.
