中文摘要：

企业发展需要政府引导、市场调节,来自于政府和市场的倒逼力量对企业经济效益的作用是本文研究的重点。＂十二五＂期间,煤炭经济发展遇到的倒逼现实是：降低煤炭能源占全部能源消费的比重、控制煤炭消费碳排放、控制单位GDP能耗、来自进口煤炭的冲击等。本文将以上因素量化为倒逼机制强度指数,并计算了71户大型煤炭工业企业的指数值,计算结果显示：政府倒逼的强度大于市场;两者倒逼指数越大,煤炭经济发展受到的限制越多,煤炭工业企业经济效益越差;煤炭工业企业资产规模变动与其经济效益显著负相关;煤炭工业企业成本费用变动对经济效益具有正向密切关系,但不显著;煤炭工业企业资产周转率、资产负债率与其经济效益呈现弱反向关系,表明煤炭企业在外部环境不利情况下,资金周转有可能失灵,如果再扩大负债,经济效益会更糟糕。

The development of enterprises needs the government guidance,market regulation. The role of the government and the market;Forced power on the economic benefits of the enterprises is the focus of this paper. In this paper,the above factors are quantified as the strength index of;Forced mechanism,and the numerical results of 71 large coal industry enterprises are calculated：The government Forced strength than the market;Both Forced index is high,the more restricted the economic development of coal,the coal industry enterprises economic benefit more poor;The coal industry enterprises asset scale changes and economic benefits significantly negative correlation;The coal industry enterprises cost change has close relation to the positive economic benefits,but not significant;The assets turnover rate, asset liability ratio and the economic benefit of the coal industry enterprises are weak and reverse relationship,Show that the coal industry enterprises in the environment condition of adverse external,the capital turnover can malfunction,if further expansion of liability,the economic benefit will be worse.
