Regional energy efficiency evaluation stands for the analysis of regional energy efficiency whose aim is to figure out the low– and high– efficient parts in energy consumption, providing most economic suggestions to improve energy efficiency. Based on the energy balance sheet, this paper decomposed the energy efficiency of one entire region into different sub-regional values and then got the energy efficiency index of each sub-region through standardized treatment. Further, the overall energy efficiency index was calculated out through weighting to lay the foundation of energy efficiency analysis and energy saving potential evaluation. Besides, this paper analyzed and compared the 2010 and 2006 energy efficiency data of China (including 30 provincial-level administrative regions) with a result that the evaluation index system of regional energy efficiency could satisfy the energy saving and managing demands, like location and analysis of regional energy efficiency level .

The energy-saving technology of the transport is still in its infancy. It has some questions about the evaluation and the promotion. Which lead to excellent energy-saving technology turn into productive forces can not be timely. In this case. The paper establishes the energy-saving technology evaluation index system by the Delphi; and calculated the evaluation index weights of each factor by the AHP. Finally, the paper proposed the evaluation method of the energy-saving technology which based on fuzzy comprehensive evaluation.

Purpose This paper aims to build a scientific evaluation index system for regional low-carbon circular economic development. Taking Sichuan Province as the empirical research object, the paper evaluates its low-carbon circular economy (LCCE) development level and proposes policy recommendations for climate change improvement based on the evaluation results. Design/methodology/approach This paper, first, built an evaluation index system with 30 indicators within six subsystems, namely, economic development, social progress, energy consumption, low-carbon emissions, carbon sink capacity and environmental carrying capacity. Second, develop an “entropy weight-grey correlation” evaluation method. Finally, from a practical point of view, measure the development level of LCCE in Sichuan Province, China, from 2008 to 2018. Findings It was found that Sichuan LCCE development had a general downward trend from 2008 to 2012 and a steady upward trend from 2012 to 2018; however, the overall level was low. The main factors affecting the LCCE development are lagging energy consumption and environmental carrying capacity subsystem developments. Research limitations/implications This paper puts forward relevant suggestions for improving the development of a low-carbon economy and climate change for the reference of policymakers. Originality/value This paper built an evaluation index system with 30 indicators for regional low carbon circular economic development. The evaluation method of “entropy weight-grey correlation” is used to measure the development level of regional LCCE in Sichuan Province, China.

Evaluation index system of traffic simulation is very important to compare the difference of several cases, which contributes to the advance of traffic simulation models and technologies. Under the concept of low-carbon, the paper establishes evaluation index system of traffic simulation. Firstly, the paper analyzes the requirements of the evaluation index system of traffic simulation from two aspects which are the application characteristics and the application under the concept of low-carbon of traffic simulation models and technologies. On the basis of analysis above, it establishes the evaluation index system of traffic simulation which concludes road network structure index, traffic operation state index, traffic environment index and traffic safety index. It proposes the application rules of evaluation index system. Then, it proposes the two-level combined evaluation method for calculating weights on the basis of comparative analysis about two methods, which are the analytic hierarchy process (AHP) method and entropy method. Finally, it applies the proposed evaluation system to calculate the comprehensive index values of two transit operation cases of Beijing Olympic Games Opening Ceremony audience evacuation. It is shown that evaluation index system of traffic simulation is practicable and effective.

A low-carbon evaluation index system for container terminals is proposed on the basis of their characteristics and the concept of low-carbon port. This system takes quantitative indexes as the core, supplemented by qualitative ones. The weight of each index is determined by AHP, and then a fuzzy comprehensive evaluation model is established according to the AHP-fuzzy comprehensive evaluation method. Finally, the proposed model is applied to a certain region of a container terminal, and the result indicates that the proposed evaluation index system and evaluation model can provide a reference for the low-carbon level evaluation of container terminals.

Facing climate change, developing low carbon economy has become an inevitable solution for China. This essay tries to establish the evaluation index system in five aspects, namely low carbon energy consuming level; low carbon technological level; economical developing level; social support level and natural environmental level. Meanwhile, by using factor analysis method and analytic hierarchy process, it comes to the conclusion that the low carbon development level of Hunan province is on a trend of increasing improvement, nonetheless there remains room for amelioration to reach the low carbon economy standard，and Finally, it propose the measures for energy saving.
