    This invention discloses a catalyst system for preparing carbamate by the direct treducing carbonylation of aromatic nitro compound and CO in alcohol. Said catalyst system comprises Pd, transition metal compounds and/or rare-earth compounds, and N-containing ligand. The reaction is conducted at 20-80 atm and 120-240 (especially 160-220) deg. C for 1-4 hours. The transform rate of nitro compound is up to 100%. The selectivity of carbamate is greater than 95%. The PhNO2]/ PdCl2] reaches over 10000 (mole ratio).
