【摘要】：選擇煤炭利潤(rùn)為研究對(duì)象,應(yīng)用SVAR模型進(jìn)行去產(chǎn)能改革前后對(duì)比實(shí)證研究,探究其與煤炭產(chǎn)能、煤炭供給、煤炭需求、煤炭?jī)r(jià)格及國(guó)際煤炭?jī)r(jià)格長(zhǎng)期均衡關(guān)系與短期波動(dòng)關(guān)系的變化。研究結(jié)果表明:改革前后煤炭利潤(rùn)與影響因素之間都存在著長(zhǎng)期均衡關(guān)系,與改革前相比,改革后煤炭產(chǎn)能增長(zhǎng)率對(duì)煤炭利潤(rùn)增長(zhǎng)率有引導(dǎo)作用,但其他因素仍無(wú)引導(dǎo)作用,更無(wú)對(duì)稱引導(dǎo)關(guān)系。改革后煤炭利潤(rùn)增長(zhǎng)率被各項(xiàng)因素沖擊的響應(yīng)幅度增大,各項(xiàng)因素在煤炭利潤(rùn)增長(zhǎng)的預(yù)測(cè)誤差方差中的貢獻(xiàn)度都有所增大,從而證明了去產(chǎn)能改革取得了一定成效,但還有繼續(xù)深化推進(jìn)的必要,并在此基礎(chǔ)上提出了改革建議。
[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.
