Preferably, when the carbonate of the ester exchange reaction is selected from one or more of the group consisting of dimethyl carbonate and ethylene carbonate and the monohydric alcohol is furfuryl alcohol, the metal-earth oxide composite catalyst is adopted. In this case, the mole ratio of the carbonate to furfuryl alcohol is in the range of 1:1 to 1:20, preferably in the range of 1:2 to 1:8; the ester exchange reaction is performed at a temperature in the range of 100° C. to 300° C. and under an absolute pressure in the range of 1.5 MPa to 8 MPa for 5 minutes to 300 minutes, preferably at a temperature in the range of 120° C. to 200° C. and under an absolute pressure in the range of 2 MPa to 4 MPa for 5 minutes to 100 minutes, preferably for 10 minutes to 40 minutes. Specifically, conversion rate of dimethyl carbonate in the ester exchange reaction is not lower than 85%, preferably not lower than 95%, and difurfuryl carbonate yield is not lower than 80%, preferably not lower than 90%.
