In Yang Xiaokai's recent writings, he criticizes neoclassical economics for its inability to handle the problems of change in economic organization. More specifically, Yang argues that the dichotomy between producers and consumers and the preclusion of corner solution in neoclassical theory cause the weakness. Trying to avoid these difficulties, Yang has begun and alternative line of research he calls "new classical microeconomics". In response to Yang's criticism, this paper attempts to show that Yang sketches an unconvincing portrait of neoclassical economics. The dichotomy hypothesis is not a useful way to understand the relationship between consumers and producers in neoclassical economics. The rationales and conditions of circumvention of corner solutions given by Yang are also incorrect. Finally, some theoretical issues related to a "new classical" model are briefly discussed, and a comparison between this "new classical" model and the standard neoclassical model is drawn. The author concludes that it is difficult to see the fundamental difference between them claimed by Yang.
