This paper aims to create an eco-city evaluation index system for Wuhan based on a data collection and comparative analysis on a large amount of cases in Wuhan, and a questionnaire survey targeting specialist and professionals. And there should be an emphasis point about the core index selection according to the character of different construction area, creating zoning control, to discuss further about the implementation of eco-city construction in planning aspect.

The city of Qingdao as an important coastal city in Shandong Province, in the 2006-2020 city plan clearly proposed to build an ecological city goals. This paper uses the optimization evaluation index system by AHP, landscape evaluation method for the construction of ecological city of Qingdao City, the evaluation results show that: the current level of ecological city construction in Qingdao City, eco city construction has a long way to go.

Abstract The sponge city concept is a new strategy for China designed to solve its urban water problems. The tasks involved in sponge city construction (SCC) have brought new challenges regarding the urban construction process for local Chinese governments. However, there is still no comprehensive and systematic study of the government mechanisms for guiding the construction of sponge cities. This paper aims to develop an evaluation index system of government mechanisms at the whole-of-nation scale. This system covers five elements of government mechanisms. This evaluation index system covers the specific content of the government mechanism anticipated before the process of SCC. Since work systems, functions, and capacities differ with each given local government, the work mechanism of local governments can be adapted to local conditions according to the research results of this paper. By doing so it is possible to make full use of the constraint and management function of each indicator, so that all departments can constantly optimize the allocation of resources and clarify responsibilities, so as to effectively promote the construction of a sponge city.

With the update and development of technologies such as IoT, the smart city revolution is boosting construction. Several excellent CBD construction projects designed in smart city construction models have emerged around the world. Exploring the construction model of the CBD through the establishment of an evaluation index system of construction effect is of great significance for CBD’s future development. The main objective of this study is to analyze the factors that affect the effectiveness of the construction of the CBD by using the Delphi method and AHP and to provide a systematic method to establish an index evaluation system for the construction effect of the smart CBD, which reflects the influencing factors of the construction effect in the CBD district from six perspectives: construction, management, service, innovation, strategy, and users. This paper also introduces the construction and development of CBD in the Jiangbei New District in Nanjing, China, and uses the indicator system established in this study to evaluate its construction effect. This paper establishes a four-level indicator system, from general to specific, and discusses the degree of impact of each indicator on the effectiveness of smart CBD construction. In order to obtain the initial evaluation data more accurately, this study classified the survey subjects into three categories, which are managers, commercial enterprise users, and ordinary residents. Finally, through the analysis of the evaluation results, the effectiveness of the construction of the Jiangbei New District CBD was evaluated, and the focus of the future smart CBD construction was pointed out. The evaluation index system for the construction effect of the smart CBD established is considered to supply a good foundation for the CBD-related study.

Effectiveness evaluations are one of the important ways to guide grid investment and to improve investment efficiency. Improving the effectiveness of grid investment evaluations is studied based on the optimization of the investment evaluation index system and the utility evaluation model. The index system is optimized by establishing an evaluation index system of grid investment effectiveness, considering the redundancy between the indices, and constructing an ISM-DEA model. The utility function model was introduced to fully consider the different risk appetites of decision-makers, and a utility evaluation model that takes risk appetite into account was established. An improved weight integration model based on multiobjective optimization was established by considering the minimum deviation and the trend-optimal objective function when setting the index weights. The calculation results show that the feasibility of the index system optimization model and utility evaluation model constructed in this study is verified under the premise of satisfying the assumptions. By adjusting the risk preference coefficient of decision-makers, the dynamic optimization of the grid investment utility evaluation results can be realized.
