Standardization of Exchanged Water with Different Properties in China’s Water Rights Trading

Abstract

Water rights trading is an effective way to optimize the allocation of water resources. However, the existing practice of water rights trading in China lacks any consideration of the practical value of the exchanged water. This deficiency may lead to disputes between transferor and transferee during the implementation of the water rights trading contract. This paper puts forward the concept of Standard Water (SW). First, getting the original value of exchanged water by the shadow price model based on input-output table; Second, based on the original value, building the economic profits or costs model to obtain the practical value of exchanged water; Third, establishing SW quantity measurement model according to the principle of rewarding excellence and punishing inferiority, so as to convert the water quantity of exchanged water into SW quantity. With the standardization method, this paper takes the water rights transaction between Dongyang City and Yiwu City in 2000 as an example to carry out case study, and provides policy recommendations. The results show that when the contract requires the provision of 49.999 million m3 water of Class I the quality, if the exchanged water quality provided is in Class II-V, the corresponding SW will be decreased to 48.699–37.399 million m3. The application of this research will be conducive to ensuring the fairness and durability of the water rights trading processes.

Dynamic Adjustment Model of the Water Rights Trading Price Based on Water Resource Scarcity Value Analysis

“…It can be seen from the scatter plot of and in Figure 3 that the actual trading price is not in direct proportion to WRSI, yet these two have nonlinear characteristics of “slow-fast-slow” change. This indicates that in the process of water rights trading, water resource scarcity is a gradual process, resulting in gradual “growth” of the water resource value [ 22 ]. Therefore, a typical growth curve, i.e., a logistic curve, was selected to represent the changing trend of WRTPE, along with the WRSI, as shown in model B: where are the model parameters, satisfying and .…”

Study on Influencing Factors and Simulation of Watershed Ecological Compensation Based on Evolutionary Game

“…The water rights transaction between Yiwu and Dongyang in Zhejiang Province is the first water rights transaction in China. It not only reduces the cost of obtaining water resources in Yiwu, but also helps Dongyang obtain economic benefits exceeding the cost of water savings, so as to achieve a win-win situation [39,40]. Based on the principle of cost sharing and benefit sharing, the Xin'anjiang River basin ecological compensation project has established a cross-province river basin ecological protection mechanism in Anhui and Zhejiang provinces, which has greatly improved the water quality and quantity of Xin'anjiang River.…”

Quantitative study on eco-economic compensation for water rights trading along the South-to-North Water Diversion Project in China

“…Water shortage has become a worldwide problem that affects sustainable development, ecology systems, and the environment (Liu 2020;Mu et al 2022). Water rights trading can address water shortage by optimizing the allocation and utilization of water resources, through the regulation of market mechanism (Bonnie et al 1993;Nir 1996;Shen et al 2020). After the completion and implementation of the SNWDP, water rights trading along the route has witnessed a steady rise.…”
