“…As far as the natural system and the social system, they are also a combination of various complex factors. Because of the "incompatibility principle" in complex systems, it is difficult to evaluate the value of water resources by using traditional value calculation methods such as the shadow price method [4], marginal opportunity cost model method [5], or the supply and demand price model [6]. At the same time, the water value system is a fuzzy system, and there is a great deal of uncertainty.…”

In view of the complexity and uncertainty of water resources, this paper chooses an evaluation index system of 13 indicators based on the fuzzy mathematics model in three aspects: water resources, water quality and socioeconomic status. The entropy method was used to determine the weight of the index, and the water resource value of Nanjing in 2011-2015 was dynamically evaluated. The results show that the price of water resources in Nanjing from 2011 to 2015 rose from 3.43 yuan/m 3 to 5.94 yuan/m 3 , showing a clear upward trend, but the corresponding price of water expenditure accounted for a proportion of disposable income from 2.27% to 1.87% during the same time period. This counterfactual trend proves that the current water price in Nanjing is relatively low and is not conducive to the efficient use of water resources. Given the fact that water prices have larger room for growth, the city government could initiate the reform of water pricing system and re-enact the water fee collection standards to achieve optimal allocation of water resources and sustainable development.

“…Researchers commonly believe that it is necessary to ensure both the quality and quantity of water resources, which must be done to meet the needs of human survival and social development, particularly at a certain stage of social and economic development. It means that the regional water environment integrated governance is not only an ecological and environmental issue, but also an issue involving social and economic factors [19,20]. To this end, this study began with the three dimensions of ecological, social, and economic benefits, and then comprehensively evaluated the performance of regional water environment governance.…”

The performance of the regional water environment integrated governance is affected by many factors. This study took place in Henan Province, China, as the research area, and constructed an index system through the comprehensive consideration of three target layers based on the Ecological-Social-Economic (ESE) framework. Due to advantages such as strong objectivity and operability, the improved entropy-weight technique for the order of preference by similarity to the ideal solution (TOPSIS) model can greatly overcome subjective human interference and render the evaluation results more reliable. Therefore, it was introduced to evaluate the water environment integrated governance in Henan from 2007 to 2016. By applying the obstacle degree model, the obstacle factors were then diagnosed. The results of this study show that the overall performance of the integrated governance was generally improved in Henan from 2007 to 2016. Performance levels of the three target layers exhibited different trends, of which the social and economic benefits presented a linear increase year by year, but the ecological benefits presented a fluctuating downward trend. The obstacle on the Henan water environment integrated governance mainly comes from the ecological and economic benefits index. Therefore, a series of countermeasures have been proposed as a means of improving the governance performance in Henan.the new era. To promote the construction of ecological civilization, the governance of environmental pollution must be accelerated as soon as possible. In this study, research into the issue of water environment integrated governance has gradually become a focal point. The formulation of a scientific and reasonable mechanism to evaluate the performance of water environment integrated governance is currently a significant issue in both the theory and practice of water environment improvement.The shortage and serious pollution of water resources are severe obstacles to meeting the demand for clean water [5,6]. Academic research on the water environment governance from different perspectives has been emerging in an endless stream [7]. At present, the research mainly includes the vulnerability of water resources [8], evaluation of water quality [9], and methods of urban water governance [10]. The construction of evaluation indexes has gradually changed from the traditional viewpoint of 'water ecological' to the more comprehensive evaluation of ecology, society and economics [11,12]. For example, Fekete and Stakhiv studied the establishment of such indicators for a performance evaluation index system, and outlined a conceptual framework for indicators suitable to guiding both the water management planning as well as implementation evaluation [13]. On the basis of the ILBM (Lake Basin Management Initiative), Chidammodzi and Muhandiki built an indicator system from two aspects, namely the water resource subsystems and socioeconomic subsystems for the evaluation of water environment governance in the Lake Malawi Basin [14].The existing rese...

Abstract:Increasing distributed generation and intermittencies, along with the increasing frequency of extreme weather events, impose a serious challenge for electric power supply security. Understanding the costs of interruption is vital in terms of enhancing the power system infrastructure and planning the distribution grid. Furthermore, customer rights and demand response techniques are further reasons to study the worth of power reliability. In this paper, the authors make use of directional distance function and shadow pricing methods in a case study of Finland. The aim is to calculate the cost of one minute of power interruption from the perspective of the distribution network operator. The sample consists of 78 distribution network operators from Finland, and uses cost and network information between 2013 and 2015.
