It is important to evaluate the impact of undesirable energy output on the climate-carrying capacity of the power grid-based economy to promote the green development. Three indicators-climate natural capacity, urban climate pressure, and urban coordinated development capacity-are used as input factors to study the climate-carrying capacity. The Nemerow index method and comprehensive evaluation method based on entropy weight are employed to calculate inputs. Pollution emissions such as carbon dioxide emissions, waste gas, wastewater, and solid waste pollution are included as energy undesirable outputs, and industry output value is included as a desirable output to calculate the non-radial directional distance of the output of climate-carrying capacity that combines desirable and undesirable outputs. The total factor non-radial directional distance function and energy-environmental non-radial directional distance function are used to obtain the efficiency index of total factor climate-carrying capacity and the efficiency of climate-carrying capacity performance, respectively. These two indices are included in the analysis to estimate the impact of energy undesirable output on climate-carrying capacity. Results from empirical analysis showed that when two types of undesirable outputs, namely waste gas and wastewater outputs, in Shanghai are constrained, the efficiency and performance efficiency of climate environmental carrying capacity are both lower than 0.8, indicating that undesirable outputs had a substantial influence on the climate-carrying capacity. In Shanghai, the major approach to improve the regional climate-carrying capacity is to improve energy efficiency and reduce undesirable outputs of power grid-based economy.

能源不良输出对气候承载能力的影响评估:以上海为例。

评估不良能源输出对电网经济气候承载能力的影响,对促进绿色发展具有重要意义。以气候自然承载力、城市气候压力、城市协调发展能力三个指标作为输入因子研究气候承载力。采用内梅罗指数法和基于熵权的综合评价法计算投入。将二氧化碳排放、废气、废水、固体废物污染等污染排放计入能源非期望输出,将工业产值计入期望输出,计算气候承载力输出的非径向距离它结合了可取的和不可取的输出。分别利用全要素非径向方向距离函数和能源-环境非径向方向距离函数求得全要素气候承载力效率指标和气候承载力性能效率。这两个指数包含在分析中,以估计能源不良输出对气候承载能力的影响。实证分析结果表明,上海在约束废气和废水两种不良产出时,气候环境承载力的效率和绩效效率均低于0.8,表明不良产出对环境产生了显着影响。气候承载能力。在上海,
