基于产能利用率的概念，运用超越对数成本函数估算了中国煤炭产业1994-2012年的产能利用率，并分析了其演变特征。研究发现：总体上中国煤炭产业的产能利用率较低，1994-2012年年均产能利用率仅为76．96％，提高产能利用率以降低固定成本的潜力较大；其次，中国煤炭产业产能利用率呈现出明显的周期性波动，近年来与经济波动的关联更紧密；最后，2012年中国煤炭产业产能利用率、煤炭价格和规模以上煤炭企业经济效益均大幅下降，煤炭产业产能过剩严重。进一步分析表明，产能集中释放、需求不振和煤炭进口冲击共同造成了中国煤炭产业2012年的严重产能过剩。

Based on the economic concept of capacity utilization , this paper measured capacity utilization in coal industry of China w hit translog cost function and analyzed its characteristics of evolution from 1994 to 2012 .We found :①From 1994 to 2012 ,the capacity utilization of coal industry is low ,annual average capacity utilization is only 76 .96% ,there is great potential for improving capacity utilization to reduce fixed cost ;②From 1994 to 2012 ,the capacity utilization of coal industry showed obvious cyclical fluctuation ,in recent years ,it is close to the economic fluctuation ;③ All of capacity utilization ,price of coal and the economic benefit of coal enterprises were substantially reduced in 2012 ,this means excess capacity is serious ,further study show s that concentration release of production capacity ,sluggish demand and coal import shock together caused serious excess capacity in coal industry of China in 2012 .
