Abstract: The present invention relates to a method for using a combination of two kinds of thermal stabilizers in a production process in order to improve the thermal stability of biodegradable polyester resins, and to biodegradable polyester resin produced therefrom. In said method, two kinds of thermal stabilizers improve thermal stability by acting complementarily with each other. Thus, a high temperature reaction is possible, and due to an increase in the reactivity, the reaction time is shortened and the molecular weight is increased. In addition, the obtained resin can provide high quality products, since the acid value thereof is reduced to improve the hydrolysis resistance thereof, and the chromaticity thereof is enhanced to thereby be capable of preventing a yellowing phenomenon of the final product.
