Professor Chengxun Yang has deepened study of the economics of socialism with Chinese characteristics. With “serving the people” as his goal, and “only the truth” as his sole reference point, he has extracted the essence of Lenin's thoughts on commodity production after a socialist revolution. He has proposed theories on developing socialist commodity economy in its early stages, and he has elaborated the mechanisms and forms of the “two leaps” in rural economy, which were originally proposed by Deng Xiaoping in 1990. Based on empirical studies, he has revealed profound contradictions in reforming state-owned enterprises. He has engaged in study of the economy of the Yellow River Basin. Prof. Yang also established a new discipline of the economics of science and technology under socialism with Chinese characteristics, within the framework of maintaining and advancing Marxist economics.
