Supporting Sustainable Development of Water Resources: A Social Welfare Maximization Game Model

Abstract

Water can carry a boat but can also overturn it (human societal sustainable development). Governments faced aquatic ecosystem restoration and preservation challenges following the establishment of the United Nations Sustainable Development Goals. This paper proposes a social welfare maximization game model to analyze the dominant strategy equilibrium of enterprise-1 and enterprise-2 based on welfare maximization under the total sewage emission control policy. Under the aforementioned control policy, a stricter total sewage emission control of an enterprise corresponds to a lower enterprise output and a higher output of a competing enterprise; that is, the profit transfer effect occurs. When the government implements a relatively strict total sewage emission control policy for an enterprise, it is beneficial to reduce the amount of sewage emission from an enterprise but has no impact on the amount of sewage emission from a competing enterprise; however, the amount of sewage reduction of both enterprises will increase. If the government does not provide capital and technical support to enterprise-2, then enterprise-1 and enterprise-2 should implement total quantity control policies with different rigor degrees to avoid the one-size-fits-all phenomenon. To maximize social welfare, the government should adjust the total sewage emission control policy in time according to sewage stock changes and focus more on enterprises with insufficient capital and poor technical skills and provide financial and technical support.

The Study Based on Intelligent Big Data Technology for Water Resources Audit

“…(2) Promote the construction of a water-saving society e promotion of the development of a water-saving society [14] is the most effective way to address the core issue of my country's water resources. Most notably, this is manifested in the following ways: adjustment of the price system for residents' domestic water and agricultural water; technical transformation of industries with high water consumption, including the recommendation of watersaving equipment; centralized treatment of sewage; and utilization of seawater after desalination, among other things [15].…”

Improvement of the Ecological Protection Compensation Policy for Adjustment of Planting Structure in an Area of Groundwater Overexploitation: A Tripartite Evolutionary Game Study

“…Irrigation accounts for about 70% of GW abstraction annually and 40% of global total irrigation [6]. GW is facing a crisis of overexploitation and pollution due to population growth, expansion of industry and agriculture, and poor management [7][8][9][10][11]. Studies have shown that GW levels have generally declined globally, particularly in the Mid-Atlantic region of the United States, California's Central Valley, northern India, the Middle East, and the North China Plain (NCP) [12][13][14][15][16][17].…”

Mathematical modeling in the Urumari micro-watershed using Streeter-Phelps mathematical models and the enhanced Do-Bod model

“…The increasing use of applied mathematical models that can translate the behavior of variables in surface waters, especially urban ones, is important in the face of the loads of pollutants in the aquatic environment (CUNHA et al, 2006;GUO et al, 2019;TEODORO et al, 2013), and they can be used to predict future scenarios. Therefore, mathematical models can be used for instructing management actions that support decisions related to the functional perenniality of environmental services, offered by urban waters.…”
