| 摘 要： 运用2006—2015年14个主要生产电解铝的省份的面板数据，研究土地要素价格扭曲和环境规制对电解铝行业产能过剩的影响并检验中介效应，考察区域异质性。研究表明：土地要素价格扭曲和环境规制分别对电解铝行业产能过剩有促进和抑制作用，二者通过投资效应对电解铝行业产能过剩产生影响；区域分析表明土地要素价格扭曲在中东部地区的影响程度相对较高，而环境规制则在西南部地区的影响程度相对较高。研究启示：完善的要素价格市场、合理的产业规划以及适当的政府干预可以减少土地要素价格扭曲对产能过剩的促进作用，并充分发挥环境规制对产能过剩的抑制作用。 |

| Abstract: By employing the panel data of 14 main production provinces of electrolytic aluminum from 2006 to 2015, the present study tests the influence of land resource price distortion and environmental regulation on the overcapacity of electrolytic aluminum industry and its mediating effect mechanism, as well as the heterogeneity effect on the overcapacity. The results show that land resource price distortion and environmental regulation are respectively promoting and inhibiting the overcapacity of electrolytic aluminum industry, and that both affect the overcapacity through the investment effect. The regional difference analysis shows that land resource price distortion has a relatively high degree of influence in the central and eastern regions, while environmental regulation has a relatively high degree of influence in the southwestern region. The research reveals that a perfect factor price market, reasonable industrial planning and appropriate government intervention can reduce the promoting effect of land resource price distortion on overcapacity, and can fully exert the restraining effect of environmental regulation on overcapacity. |
