Besides in actual pricing operation, from the angle of protection cost, water price characterizes the cost of controlling pollution and protecting water environment. Based on the two factors of water environment capacity and ecological water consumption embodied by the environment water price, this paper puts forward an effective environmental water price calculation model based on three elements of sewage treatment fee, ecological water price and water quality maintenance fee. And this paper takes the data of Hefei as an example, calculates reasonable environmental price, comparing which with the existing price, and finds the main existing problem which needs to be solved urgently in management.展开更多

The price of water resources can also be considered as a “water resource tax” which reflects the value and opportunity cost of water, and people will pay for the right to use water. Currently, the water resource fees’ effect of regulating resource differential revenues is not manifest and it’s not enough to reflect the principle of paid use of resources as well as regulating resources differential revenues. Due to the ambiguity and complexity of water resources price, this paper uses methods relating to fuzzy mathematics for modeling and processing. The study had a comprehensive consideration of five factors including water quality, water resources per capita, household consumption level, per capita GNP, population or population density to evaluate the water resource price.展开更多

The theory of new institutional economics which produced the environmental property theory is widely used in the research of environmental management. On the premise of total amount control of pollution, the subjects of public power distribute or sell the rights is the basic paradigm of this method. Buyers take possession of the rights and utilize, profit from or dispose of them. The coordinated development of urban agglomeration is the main direction of China’s regional development strategy. As there are differences in environmental governance in different cities, the environment property trading system of urban agglomeration needs to be established urgently. Due to environmental property’s complexity and its attributes of public goods, the transaction of environmental property is restricted by amounts of factors. This research concludes that it is necessary to define the possessor of environmental property, strengthen the construction of trading platform, improving the public participation and supervision mechanism and control transaction cost by establishing and analyzing the emission trading model of the city-cluster along the Yangtze River in Anhui Province.展开更多

It presents different characteristics in different countries or regions. In 2006, China proposed the national strategy to build an innovation-oriented nation and subsequently approved more than 60 pilot cities in the country. The research on China’s innovation-oriented city assessment system is also increasing. On the basis of predecessors, this paper constructs innovation-oriented city evaluation indicator system with more links based on innovation link. It has three categories with 44 indicators in total according to input, intermediate output and final output. It creatively introduces in two-stage DEA model on sharing input and constructs the evaluation model based on the above evaluation indicator system. This paper makes an empirical analysis on the innovation-oriented cities in Yangtze River Delta including Hefei, arrives at innovation efficiency difference and puts forward some countermeasures and suggestions for the analysis results.展开更多
