摘　　要：从市场集中度与市场绩效的一般理论关系来看,市场集中度与产业利润率呈现正相关关系,但与市场绩效呈现负相关关系,如市场集中度低、利润率低但市场绩效好。然而,运用产业组织理论的这种关系对中国房地产业的市场集中度及市场绩效进行分析,发现中国房地产业明显地存在着市场集中度与产业利润率之间呈负相关关系、与市场绩效呈现正相关关系、表现为低集中度、高利润率、低市场绩效的现象。探讨产生这一悖论现象的原因,并提出促进中国房地产业有效发展的政策建议,目的在于实现中国房地产业发展的市场集中度与市场绩效的有效统一。By explaining the general relationship between market concentration ratio and market performance,this paper has an idea that market concentration ratio has a positive relationship with industry profit rate but a negative relationship with market performance,such as low market concentration ratio,low profit rate but good performance.On the basis of discribing the practical development of Chinese real estate industry, the paper analyzes the market concentration ratio and market performance during the period of 2002—2005 and finds out that market concentration ratio has a positive relationship with industry profit rate hut a negative relationship with market performance,low market concentration ratio,low profit but good per- formance.Moreover,the paper discusses the reasons for this paradox phenomenon from some aspects and finally puts forward the policy choices which promote efficient development of Chinese real estate industry in order to achieve the unification of the market concentration ratio and market performance.
