【摘要】：选择煤炭利润为研究对象,应用SVAR模型进行去产能改革前后对比实证研究,探究其与煤炭产能、煤炭供给、煤炭需求、煤炭价格及国际煤炭价格长期均衡关系与短期波动关系的变化。研究结果表明:改革前后煤炭利润与影响因素之间都存在着长期均衡关系,与改革前相比,改革后煤炭产能增长率对煤炭利润增长率有引导作用,但其他因素仍无引导作用,更无对称引导关系。改革后煤炭利润增长率被各项因素冲击的响应幅度增大,各项因素在煤炭利润增长的预测误差方差中的贡献度都有所增大,从而证明了去产能改革取得了一定成效,但还有继续深化推进的必要,并在此基础上提出了改革建议。
[Abstract]:Choose coal profit as the research object, use SVAR model to carry on the comparative research before and after the reform of deproductivity, explore its and coal production capacity, coal supply, coal demand, The change of long-term equilibrium relation and short-term fluctuation relation between coal price and international coal price. The results show that there is a long-term equilibrium relationship between coal profits and influencing factors before and after the reform. Compared with before and after the reform, the coal productivity growth rate has a guiding effect on the coal profit growth rate, but other factors still have no guiding role. Moreover, there is no symmetrical guide relation. After the reform, the response range of coal profit growth rate is increased by the impact of various factors, and the contribution of each factor to the variance of forecast error of coal profit growth is increased, which proves that the deproductivity reform has achieved certain results. But there is a need to continue to deepen the push, and on this basis put forward reform proposals.
