中文摘要：

以定价理论和假设条件为前提,运用演绎的方法推理和构建生态环境约束的能源定价模型。在此基础上,以甘肃省作为经验分析对象,测算其生态环境质量和生态环境约束的能源价格;同时分析和总结生态环境约束条件下甘肃省能源价格的变化特征和变化规律。研究结果表明：同一年份中随着生态环境质量水平的下降,甘肃省煤炭、石油、天然气、电力以及综合能源均衡价格呈现出下降特征;在同一生态环境质量水平上,随着时间推移,甘肃省煤炭、石油、天然气、电力以及综合能源均衡价格呈现出上升的特征;不同年份、不同生态环境质量水平上,甘肃省煤炭、石油、天然气、电力以及综合能源的生态环境约束价格均高于实际价格。

英文摘要：

On the premise of pricing theory and by using deductive methods, the energy pricing model un- der ecological environment constraints is constructed, based on which ecological environmental quality and energy prices under ecological environment constraints in Gansu province are measured. At the same time, the characteristics and patterns of energy price changes under ecological environment constraints are ana- lyzed and synthesized. The result shows that in the same year as the level of the ecological environment qual- ity decreases, the equilibrium price of coals, oil, natural gas, electricity and integrated energy declines; on the contrary, with the level of the ecological environment quality being stable, as time advances, the equilibri- um price of coals, oil, natural gas, electricity, and integrated energy tends to rise. Regardless of the year or the level of ecological environment quality, energy prices under ecological environment constraints in Gansu province are higher than they theoretically should.
