我国煤炭产业规模、结构与技术水平分析
Analysis on the Scale, Structure and Technological Level with Regard to China’s Coal Industry
摘要
Abstract
In order to understand the characteristics of the coal industry in China in a scientiifc manner, this paper quantitatively evaluates the scale, structure and technological level with regard to China’s coal industry in accordance with statistical model and index system. The results show that although China has the world's largest coal production scale, the market structure still lags far behind advanced coal countries. From 2005 to 2012, the CR8 value of the Chinese coal industry basically stabilized between 22% and 36%, which, according to the 40% Bain standard, had a certain distance; the HHI index of the corresponding period was less than 500, meaning the Chinese coal industry was a type II market. In terms of technical level, since 2005, coal mining mechanization level, the utilization of coal gangue and mine water have increased at a high speed, yet the progress of recovery ratio, selection rate of raw coal, and coal mine gas extraction efifciency have made relatively slow.关键词
