Abstract: Based on the dynamic panel data of 30 provinces in China from 2001 to 2016, the deepening level of financial capital is measured from the scale and structure of capital supply. The quality of economic development is measured by using the five dimensions of effectiveness, stability, coordination, sustainability and sharing of economic growth. The influences of deepening the financial capital on the quality of economic growth are investigated by means of the estimation method of system GMM model. The results show that the current scale of capital supply has inhibitory effects on the quality of economic growth. The deepening of bank capital and insurance capital has positive effects on the quality of economic growth. The deepening of security capital has no significant effects on the quality of economic growth. There are regional differences in the effects of deepening financial capital on the quality of economic growth.

Abstract: To study the spatial features of regional water use and the mechanisms of economic growth and regional water use, the spatial panel STIRPAT model is introduced to analyze the relationship between the economic growth and the water use in the overall, eastern, central and western regions of China. The results show the economic growth and the water use in China are greatly spatially correlated, and they have several types of EKC curves. From the perspective of the overall level in China, the relationship between the economic growth and the water use exhibits an inverted “N-shaped” curve, with two turning points at 7358.79 and 60668.53 CNY GDP per capita, and the curve of most provinces is at the climbing stage before decline stage except a few eastern regions. The curves of the relationship between the economic growth and the water use in eastern and central regions monotonically decrease and increase, and those in the western regions also exhibit the inverted “N-shaped” ones with two turning points at 521.52 and 35225.87 CNY GDP per capita, indicating that although the water use will decline in short term, the economic development-water use dilemma will exist in long term according to the estimated results. Furthermore, there are no EKC turning points by using the traditional panel models without the consideration of the spatial correlation, implying that there will be large errors of the GDP per capita corresponding to the peak water use in China neglecting the correlation of regional water use when using the traditional approaches.

Abstract: According to the characteristics of ecological benefits of water resources, the market value method and human cost method are selected to quantify the ecological benefits of water resources from three aspects: soil and water conservation, water quality improvement and drinking water safety. The ecological benefits of water resources in China from 1990 to 2015 as well as those in Shaanxi and Jiangsu provinces are estimated. The results show that the ecological benefits of water resources in China generally increase, but compared with the economic benefits of water resources, the proportion is still low. The main problems faced by the ecology of water resources in different regions are also different. It is necessary to further strengthen the investment and construction of the ecological benefits of water resources. At the same time, measures should be taken according to the local conditions to solve the main problems in various areas.

Abstract: The actual operating costs of Eastern Route Project of South-to-North Water Diversion are the key factor in the formulation and adjustment of water supply prices. According to the specific characteristics, the accounting mode “dual-system and step-by-step” of the operating costs of Eastern Route Project is established based on the principles of full cost accounting and benefits from the perspective of accounting. It includes the operating cost accounting both in enterprise accounting system and the water supply pricing support system. In the former system, the cost collection, allocation and carry-over are carried out from five cost elements: water diversion costs, manufacturing overheads, taxes and surcharges, administrative expenses, and financial expenses. In the latter system, the cost allocation methods among different functions and sections are proposed based on the cost behavior analysis. The proposed cost accounting method can be used to develop the operation cost accounting information system of Eastern Route Project and realize the unified, standardized accounting and management of its operating costs. It may provide useful cost information for decision-making of water supply pricing and supervision and examination of government costs.

Abstract: In view of the problems of different credit evaluation cycles, long evaluation cycles and unscientific evaluation methods of the entities of the water conservancy construction market, the weights of the credit evaluation indices referring to the existing credit evaluation indices of the entities of the water conservancy construction market are determined by means of the comprehensive empowerment approach so as to ensure their rationality. The comprehensive credit evaluation values of a water conservancy construction enterprise are obtained by using the proposed fuzzy comprehensive evaluation method. Based on the historical data, the final dynamic evaluation values of credit are obtained. Finally, the dynamic prediction values of credit level are given by the Markov model. The results show that the dynamic credit evaluation model for the entities of the water conservancy construction market is effective and feasible for the credit evaluation of the water conservancy construction enterprises, and the prediction values of credit obtained by the Markov model can provide reference for the selection of water conservancy construction enterprises.

Abstract: With the increase of environmental governance in China, PPP projects of water environment governance account for a large proportion in infrastructure construction. However, due to the lack of systematic index system, evaluation methods and assessment tools, it is difficult to theoretically evaluate the status quo of urban water environment and its sustainability after treatment in China. With the help of the theory of set pair analysis, the sustainability evaluation model for PPP projects of water environment treatments is established based on the five-element connection number, and the PPP project in Xuchang City is taken as the case study. The results show that the overall sustainability of the project is strong, and there is an upward trend, but the sustainable management of the project company is in a downward trend, to which attention should be paid. Using the set pair analysis model, the sustainability and trend of the whole project as well as the trend of each evaluation index can be obtained, which provides a basis for the project to improve or maintain its sustainable decision-making.

Effectsofenvironmentaldecentralizationonwaterenvironmenttreatment:dynamicpaneltestsfromtheperspectiveoffiscaldecentralization/PAN Haiying, LU Min (Business School, Hohai University, Nanjing 211100, China)
Abstract: Based on the panel data of 30 provinces (municipalities and autonomous regions) in China from 2002 to 2015, the effects of environmental decentralization on water environment treatment are empirically tested by using the method of system GMM. The results show that the environmental decentralization has a significant and stable positive relationship with the three types of water pollution indices, namely, discharge of industrial and domestic wastewater (DID), ammonia nitrogen emission from industrial wastewater (HN_I), and chemical oxygen demand of industrial wastewater (COD_I). It means the excessive autonomy of local governments in environmental management is detrimental to water environmental governance. The fiscal decentralization also has a negative effect on water environment governance. With the improvement of the fiscal decentralization, the adverse impact of the environmental decentralization on the effects of water environment treatment is strengthened. The group tests reveal the negative effects of the fiscal decentralization on water environment governance are becoming less obvious due to the central policy intervention and the reform of environmental management system, and the moderating effects of the fiscal decentralization are also effectively weakened. To some extent, the environmental decentralization having better effects in the eastern areas than those in the central and western areas reduces the water pollution discharge in the eastern coastal areas. At the same time, the negative effects of the fiscal decentralization on water environment governance and its moderating effects are more significant in the central and western areas.

Abstract: According to the theory of catchment disaster system, firstly 9 risk evaluation indices are selected considering disaster-causing factors, disaster-pregnant environment and disaster-bearing bodies, the sample data are used to manually identify risks and to obtain training samples, and a risk assessment model for flood disasters is established by using the random forest algorithm based on the random forests. Secondly, the self-assessment tools of the random forests are employed to analyze the model errors and indexes, and the support vector machine model is established as a comparison scheme. The 5-fold cross-validation method is used to validate the above two models. Finally, the Qiuzhuang catchment of Haihe River Basin is taken as the research object to evaluate and compare the evaluation models based on the random forests and the support vector machine with the same data. The results show that the total rainfall in 12 hours, duration of floods and water content of soils are the main factors to cause floods. The training and testing accuracies of the risk assessment of flood disasters based on the random forests are both higher than those of the support vector machine.

Abstract: The risks of water resources and water environment in the exploitation process of shale gas are analyzed. On this basis, the risk assessment index system for risks of water resources and water environment in the exploitation process of shale gas is established, specifically including three categories: risk of water resources, risk of surface water pollution and risk of groundwater pollution. Then the proposed assessment system is applied to a case study, and the risks of water resources and water environment of a shale gas project in Sichuan Province of China are investigated. The results show that the overall assessment of the shale gas project is of higher risks, among which the risk of water resources is low, that of surface water pollution is lower, and that of groundwater pollution is higher.

Abstract: The three-stage DEA method is used to study the relevant data of water for production in Jiangsu Province from 2010 to 2017 by selecting the water for production, labor forces and input of fixed assets of industrial sector as the input indices, the regional gross domestic product as the output index, and annual precipitation, compliance rate of water functional areas and ownership of water resources per capita as the environmental variables. The results show that there are five years which are non-DEA effective at the first stage, mainly owing to that the unreasonable allocation of resources affects the utilization efficiency of water for production. After eliminating the influences of environmental variables, non-effective management and random interference at the second stage, the efficiency values of the third stage are improved, and the environmental variables mainly affect the water for production. Although the comprehensive efficiencies of the first and third stages are different, the overall change trend is the same, that is, the utilization efficiency of water for production from 2011 to 2015 decreases to some extent, it gradually increases after 2015 and reaches the optimum status of utilization in 2017. Finally, some suggestions are put forward for improving the utilization efficiency of water for production in Jiangsu Province.

Abstract: The oversized construction investment projects involve many stakeholders in the process of construction. It is very important for the projects to solve the conflicts of interests among different actors and the game of interests of the key stakeholders. Based on this problem, the matrix of the key stakeholders of the oversized construction investment projects is established, namely, the constructor, the project owner, the local government and the immigrants through the social network analysis. And then based on the evolutionary game theory, the conflicts of the key stakeholders are analyzed to find out the key factors that affect the equilibrium of the game by using the dynamic evolutionary game model as well as how to balance the interests between them. Finally, according to the analysis results, the countermeasures are put forward to improve the supervision and management system and to establish a reasonable immigration management system.
