Abstract: This paper first applies economics theories to study on characters of ready-mixed concrete industry. Then the market structure of the industry and the results of malignant competition are deeply studied. At last the policy implication is summarized. The analysis suggests that ready-mixed concrete industry tends to fall in malignant competition, which may cause many serious problems. Therefore, in order to maintain the healthy development of ready-mixed concrete industry in China, it is required that the government should put the development of ready-mixed concrete industry under macro-control.
