摘要
我国煤炭市场的买方集中程度逐年提高。当我国经济处于快速增长时期,煤炭下游(耗煤产业)市场势力与煤炭产业集中度高度正相关。同时煤炭买方(耗煤产业)市场势力与煤炭行业利润率显著正相关,主要是由经济上行期能源需求旺盛和市场集中程度增速较快决定的。动力煤生产商议价能力较弱,最主要的耗煤产业——电力工业,由5个国有发电企业寡占,电力市场势力的日趋强大对煤炭产业利润率的负面影响不大。
Measures of buyer market structure in China＇s coal industry such as DSPH and BCR are computed. The growing buyer＇s concentration has a high positive correlation with the seller concentration, and with the seller＇s profits. This can be attributed to the demand conditions and the difference between the “marginal” growth of concentration of the upstream and down-stream industries. The concentration rate of China’s electric power industry is calculated, showing that monopoly in the electric industry has insignificant impact on coal prices.
