The invention relates to a new method for generating bisphenol A and dimethyl carbonate by solvent waste polycarbonate and chemical degradation waste polycarbonate material under a moderate condition to realize recycling of waste polycarbonate material. The method is characterized in that tetrahydrofuran, drewamine, N-methyl-pyrrolidone, 1, 2-dichloroethane, N, N-dimethyl formamide, diethylamine, ethylene dimine or composite material thereof which are easy to be recycled are used as reaction media, and with the presence of catalysts of sodium hydroxide, sodium carbonate, potassium hydroxide, potassium carbonate, lithium hydroxide or composite material thereof, and the like, an alcoholysis reaction is carried out under a normal pressure or a high pressure and at reaction temperature of 20 DEG C-80 DEG C; and a hydrolysis reaction is carried out at reaction temperature of 50 DEG C-160 DEG C. After the reactions, product bisphenol A is obtained (alkyl dimethyl easter product is also obtained in the alcoholysis reaction) after operation processes of solvent removing, washing, drying, and the like are carried out to the reaction liquid. The deterioration rate is over 98 percent. Compared with the traditional methods, the new method for generating bisphenol A and dimethyl carbonate by solvent waste polycarbonate and chemical degradation waste polycarbonate material under a moderate condition to realize recycling of waste polycarbonate material is characterized in that: (1) the reaction conditions are moderate; the reaction speed is high; and the operation is easy and simple; and (2) the problems of long reaction time period and strict requirements for equipment condition existing in the background technology, and the like, are overcome.
