摘要:近年来,中国经济保持快速增长,投资对经济增长发挥了主要的拉动作用。但由于受资源和消费需求等的限制,伴随着过快的投资增长,不少行业和地区不同程度地出现了“投资过热”现象,从而引发一系列问题,如能源和原材料的紧缺、产能过剩、经济结构扭曲、重复建设等。由于过度地投资,大量的资本沉淀在生产能力过剩从而盈利能力恶化的领域,同时也减弱了经济增长吸纳劳动力的能力,制约着经济、环境与社会的协调发展。

　　　本文对产能过剩形成机理给出一个全新的解释，在界定产能过剩概念基础上，给出了衡量产能过剩的理论标准；并对产能过剩的效应进行经济学分析；文章最后就缓解产能过剩提出相关政策建议。

Abstract:In recent years, Chinese economy keeps a fleet rate of increase. And investment plays an important role in the development of Chinese economy. But because of the restrict of resource and consume demands, "hot invest" phenomenon appears in many industry and regions accompany with the excess increase of the investment, which causes series of problems, such as tight lack of energy and original materials, the excess of productive ability, the distort of economic construction, the repetition of development etc. Because of excessive investment, a flood of capital precipitates at some realms with excess production ability and poor profit ability. Excessive investment also reduces the ability of absorbing labor force in economy increase, making difficulty in the coordination development of economy, environment and society.

　　　This paper intends to explain how excess production capacity occurs. Based on defining what excess production capacity is, by using relevant literatures for reference, the paper establishes a special theory model. Enacting a new standard of weighing over-through-put, analyzing the economic effect of over-through put. Finally, some policy suggestions are put forward .
