摘要
以2006年~2014年行业的相关数据为基础,构建VAR模型,通过Johansen协整分析、脉冲响应函数分析、方差分解分析的方法对煤炭行业投资效率和去产能过程中涉及的主要因素进行实证研究,结果表明,以提高产能利用率、增加资源整合度、遏制过剩产能投资为主要方式的产能出清对提高行业投资效率有显著的正向作用,是行业脱困的现实选择。
Based on the industry related data in 2006-2014,constructed a VAR model and employed Johansen co-integration analysis,impulse response function and variance decomposition analysis method in order to conduct empirical research of coal industry investment efficiency and the main factors of reducing production capacity. The result reveals that clearing capacity dominated by improving capacity utilization, increasing resource integration degree and curbing overcapacity investment has significant positive effect to improve the efficiency of investment,and it is also a realistic choice of the industry experiencing difficulties.
