市场经济条件下,由于分散决策和信息不对称等原因,产能过剩的存在具有客观必然性。适度的产能过剩也有利于发挥竞争机制的作用。然而,现阶段,我国钢铁行业的产能过剩已经超出正常市场竞争的范围。严重产能过剩已经导致钢铁产品供大于求、价格下行,造成市场恶性竞争、行业亏损扩大、企业经营困难、职工下岗失业、不良贷款增加、资源瓶颈加剧、生态环境恶化等问题,直接危害产业健康发展和经济平稳运行,甚至可能引发系统性风险,影响民生和社会稳定大局。因此,化解严重产能过剩,是加快经济发展方式转变的重要切入点,是当前及今后一个时期推进产业结构调整的重中之重和当务之急。一、以往投资规制政策合理性探讨回顾以往出台的钢铁产业各项政策,我们可以看出,以严格的投资项目审批、市场准入为手段的投资规 Under the condition of market economy, due to the reasons such as decentralized decision-making and information asymmetry, the existence of excess capacity has the objective necessity. Moderate overcapacity is also conducive to play a role in competition mechanisms. However, at this stage, China’s steel industry overcapacity has exceeded the scope of normal market competition. Serious overcapacity has led to steel products oversupply, the price down, resulting in the vicious competition in the market, industry losses expanded, business management difficulties, laid-off workers, non-performing loans, increased resource bottlenecks, the deterioration of the ecological environment and other issues directly endanger the healthy development of the industry And the stable operation of the economy may even trigger systemic risks and affect livelihood and social stability. Therefore, resolving serious overcapacity is an important entry point to speeding up the transformation of the mode of economic development, and it is a top priority and top priority for promoting industrial restructuring in the current and future period. First, to explore the rationality of investment policies in the past Recalling the previous steel industry policies, we can see that the strict investment project approval, market access as a means of investment rules
