煤电价格联动作为一种由政府定价向市场定价转化的过渡性体制安排,对于化解煤电冲突具有重要的现实意义。基于复杂网络模型,定量分析不同政策情景下的煤电价格联动机制的影响效应。研究发现:煤电价格联动政策对煤、电产业自身以及冶金、采矿和石化等资源密集型产业影响较大,该类产业可视为煤电联动政策影响效应的重点监测部门;不同政策情景下,煤电价格联动机制对宏观经济的影响有所差异,但各产业价格指数与煤、电价格变化趋势趋于一致;若煤价变幅不大,新煤电价格联动机制(α=0.9)能够降低其对物价水平的影响,反之,原煤电价格联动机制(α=0.7)能够降低煤电价格波动对物价水平的影响,而新煤电价格联动机制放大了煤、电价格波动对物价水平的影响。基于上述结论,提出健全煤电市场交易体系、动态调整煤电价格联动机制的建议,以求建立煤炭价格对电力上网定价的倒逼机制,逐步形成合理的电煤价格运行和调节机制。
Coal and electricity price linkage as a transition from government pricing to market pricing institutional arrangements, to resolve coal-electricity conflicts has important practical significance. Based on the complex network model, this paper quantitatively analyzes the impact of coal price-electricity linkage mechanism under different policy scenarios. The study found that the coal price linkage policy has a great impact on the coal and electricity industries as well as the resource-intensive industries such as metallurgy, mining and petrochemical industries. Such industries can be regarded as the key monitoring departments for the impact of coal-electricity linkage policies. Under different policy scenarios However, the effect of the coal price and electricity price linkage mechanism on the macroeconomy is different, but the trend of the price index of various industries tends to be consistent with that of coal and electricity prices. If coal prices fluctuate less, the new coal price and electricity price linkage mechanism (α = 0.9) On the contrary, the coal-electricity price linkage mechanism (α = 0.7) can reduce the impact of coal price fluctuation on the price level, while the coal-electricity price linkage mechanism has enlarged the impact of coal price fluctuation on the price level Horizontal impact. Based on the above conclusions, this paper puts forward suggestions on how to improve the trading system of coal electricity market and dynamically adjust the linkage mechanism of coal price and electricity price so as to establish the mechanism of feed-in price of coal price on power grid pricing and gradually form a reasonable coal price operation and adjustment mechanism.
