Ushbu tezisda O'zbekiston bank tizimida raqobat darajasi Panzar-Rosse H-statistikasi va Boone indikatori asosida panel ekonometrik tahlil yordamida baholangan. 2016–2025 yillar uchun 20 ta tijorat bankining rasmiy hisobotlari asosida shakllantirilgan 200 kuzatishli panel ma'lumotlar to'plamida Arellano-Bond GMM modeli qo'llanildi. H-statistikasining 0,514 qiymati O'zbekiston bank sektorining monopolistik raqobat zonasida joylashganini, Boone indikatorining 2016 yildagi −0,18 dan 2025 yilda −0,46 ga o'zgarishi esa raqobatning sezilarli kuchayganini empirik isbotlaydi.

Kalit soʻzlar:
