摘　　要：低碳经济是应对气候变化的必然选择,如何全面客观地评价一个国家或经济体低碳经济发展水平成为低碳经济研究中迫切需要解决的问题。本文充分考虑低碳经济发展规划和目标,采取修正的TOPSIS方法构建低碳经济评价模型。针对传统TOPSIS方法中存在两个不足:一是相对贴近度计算中将被评价对象到“正理想解”和到“负理想解”的距离直接相加,正向指标和负向指标直接相加是不合理的;二是传统的TOPSIS方法忽略了被评价对象与“正理想解”和“负理想解”的距离的权重分配问题。本文提出利用密切值法对传统TOPSIS方法进行修正,解决到正负理想解两个距离的组合问题。首先,通过密切值的引入将被评价对象到“正理想解”和“负理想解”的距离转化为同向指标,保证了两个距离可以进行运算;然后,对两个距离进行归一化,保证两个距离在相同的数量级上,保证备选方案到正理想解的距离和到负理想解的距离起相当的作用,再根据决策者的偏好,对两个归一化的距离进行权重分配,保证两个距离分配的权重确实体现了决策者的意愿;最后,通过对秦皇岛市的低碳经济评价验证修正TOPSIS评价模型在低碳经济评价下的可行性和有效性,解决了评价指标有目标约束下的低碳经济评价问题。Low carbon economy is an inevitable choice to deal with climate change.How to evaluate the development level of low‐carbon economy of a country comprehensively and objectively has become an urgent issue in the research of low‐carbon economy.A low‐carbon economy evaluation model was built by the modified TOPSIS(technique for order preference by similarity to an ideal solution)method with the consideration of the development planning and goals of low-carbon economy.There are two shortcomings in traditional TOPSIS.First,the distance from the evaluated object to the“ideal solution”and to the“negative ideal solution”is added directly in the calculation of relative closeness,which is unreasonable to add the positive index and the negative index directly;second,the traditional TOPSIS method ignores the weight distribution problem of the two distances to the positive and negative ideal solution.The osculating value method was proposed to modify the combination problem of two distances to positive and negative ideal solutions in the traditional TOPSIS method.Firstly,the distance from the evaluated object to“ideal solution”and“negative ideal solution”was transformed into the same direction index through osculating value,which ensures that the two distances can be calculated.Secondly,normalized the two distances to ensure that they are in the same order of magnitude,and that the distance between the alternatives and the ideal solution is equivalent to the distance between the alternatives and the negative ideal solution.Then,according to the preference of the decision‐maker,distributed the weight of the two normalized distances to ensure that the weight distribution of the two distances really reflects the will of the decision-maker.Finally,through the low‐carbon economic evaluation of Qinhuangdao City,the feasibility and effectiveness of the modified TOPSIS evaluation model under the low‐carbon economic evaluation were verified,and the problem of low‐carbon economic evaluation with objective c
