通过对中国煤炭产业的买方市场势力的量度,得到趋势向上的结论。目前买方市场势力与煤炭产业集中度高度正相关、与利润率显著正相关,与后者的关系与大多数实证结论相悖,究其原因是中国目前煤炭需求的特殊性和产业“边际”集中度增速较快。通过测算煤炭细分市场———炼焦煤市场的集中度,认为其市场结构特征是寡占型;追踪最新的钢铁行业市场结构变化特征,研究结论是钢铁产业集中度的提高推动了炼焦煤市场价格。国家产业政策应鼓励电力企业后向一体化,加快钢铁、水泥等产业兼并重组,促进产业均衡良性发展,确保国民经济稳定运行。
Through the measurement of the market power of buyers in China’s coal industry, the trend is up. At present, the market power of buyers is highly positively correlated with the concentration of the coal industry and positively correlated with the profit rate. The relationship with the latter is contrary to most of the empirical conclusions. The reason is that the current demand of coal in China is very special and the industry Concentration growth rate faster. By measuring the concentration of the coal market - the coking coal market, the market structure is characterized by oligopoly. The latest structural characteristics of the steel industry are tracked. The conclusion is that the increase in the concentration of the iron and steel industry has promoted the market price of the coking coal . National industrial policies should encourage the backward integration of power enterprises, speed up the merger and reorganization of industries such as steel and cement, promote the balanced and benign development of industries, and ensure the stable operation of the national economy.
