Penelitian ini bertujuan untuk menganalisis pengaruh credit rating terhadap struktur modal pada perusahaan non-keuangan yang terdaftar di Bursa Efek Indonesia periode 2006-2012. Pengujian ini dilakukan menggunakan metode regresi data panel, dimana variabel dependen adalah net debt issued (NetDIss) atau hutang yang diterbitkan setelah dikurangi ekuitas sebagai proksi struktur modal, sedangkan credit rating sebagai variabel independen diproksikan sebagai variabel dummy. Metodologi yang digunakan adalah Plus or Minus Test, Credit Score Test, dan Investment Grade Non-Investment Grade Test. Hasil penelitian menunjukkan bahwa credit rating berpengaruh signifikan terhadap struktur modal. Dimana, berdasarkan pengujian POM test didapatkan hasil bahwa credit rating yang mendekati peningkatan (upgrade) dan penurunan (downgrade) berpengaruh signifikan terhadap struktur modal. Investment Grade Non-Investment Grade test juga menunjukkan hasil bahwa credit rating yang berada pada batas kategori investment grade non-investment grade berpengaruh signifikan terhadap struktur modal. Sedangkan, Credit Score test menunjukkan hasil bahwa credit rating tidak berpengaruh signifikan terhadap struktur modal perusahaan non-keuangan di Indonesia.
