针对转型期发电市场中相关管制政策实施后出现的问题,通过建立评价指标体系,将抽象的改革要求及政策管制目标,系统转化为可计量的考核指标,并运用系统动力学流率基本入树的建模和分析方法,量化分析相关管制政策实施效果。分析结果表明:①联动涨幅最低标准、联动比例、煤价涨幅及政策实施的及时性,是影响煤电价格联动政策实施效果的关键因素;②盈利能力分化程度、能耗高小机组生存能力和需求预测准确性,是影响标杆电价、上大压小和投资项目核准政策实施效果的重要原因;③如采用适当控制煤价及需求增长幅度、调整联动涨幅最低标准及联动比例等改进措施,可起到缓解煤电价格矛盾、改善机组盈利能力、提振投资信心和促进供求平衡的作用。
針對轉型期髮電市場中相關管製政策實施後齣現的問題,通過建立評價指標體繫,將抽象的改革要求及政策管製目標,繫統轉化為可計量的攷覈指標,併運用繫統動力學流率基本入樹的建模和分析方法,量化分析相關管製政策實施效果。分析結果錶明:①聯動漲幅最低標準、聯動比例、煤價漲幅及政策實施的及時性,是影響煤電價格聯動政策實施效果的關鍵因素;②盈利能力分化程度、能耗高小機組生存能力和需求預測準確性,是影響標桿電價、上大壓小和投資項目覈準政策實施效果的重要原因;③如採用適噹控製煤價及需求增長幅度、調整聯動漲幅最低標準及聯動比例等改進措施,可起到緩解煤電價格矛盾、改善機組盈利能力、提振投資信心和促進供求平衡的作用。

In view of the existing problem arising in the power generation market after implementing the correlated regulatory policy, a countable evaluation index system is built to systematically transfer the abstract reform request and the regulatory goals into quantifiable examination index. Then a modeling and analyzing method of rate variable based in-tree in system dynamics is used to quantitatively study the effect of correlated regulatory policy implementation. The results show that: ①the key factors influencing the implementing effect of the coupled coal-electricity policy include the lowest linkage coal price rises, the linkage ratio, the coal price increase, and the timeliness of the policy implementation; ②the main factors influencing the implementing effect of other regulatory policies, such as benchmark price, approval system of enterprise investment project, and replacing small units with large ones, include the different profitability, the loss of survival ability of the old unit, and the reliability of the power demand forecast;③if such improved measures as controlling the coal price rises and power demand, and adjusting the lowest coal price rises and the linkage ratio are taken, it may take effect in relieving the coal and power price contradiction, improving the unit profitability, inspiring the investment, and promoting the balance between power supply and demand.
