The Sustainable Development

System dynamics was used to analyze the sustainable development issues of flood detention basin form the perspective of economic, population, resources and environmental. Based on the analysis of the subsystems characteristics and internal factors affect between the various subsystems constructed Dongting Lake flood detention basin’s system dynamics model of sustainable development was build. Constraint and exogenous variables analysis based on the model structure was taken. And from the perspective of economic planning, population control and River Basin Compensation, offered proposals for the promotion of Dongting Lake flood detention basin’s sustainable development.

High Quality Service

Developing countries need a large number of social infrastructure projects (e.g. schools, medical care, nursing homes). But the government’s finance to invest in these projects is limited. By using the public–private partnership (PPP) mode to attract social capital to invest in PPP projects, it can relieve the financial pressure and improve the operation efficiency. The cooperation between government and consumer can ensure the sustainable development of the project operation. A system dynamics model of tripartite evolutionary game is developed to analyze the interaction of participant’s strategies and simulate the corresponding evolution process. We employ the scenario analysis method to investigate the impact of the key parameters in relation with PPP projects based on realistic scenario assumptions. The results reveal the effect of some policies including reverse effect, blocking effect and over-reliance effect. Specifically, the results show that high penalty can prevent social capital from providing low-quality services, the low cost of government regulation can promote social capital to provide high-quality services, compensation to consumer can increase the enthusiasm of consumer participating in supervision, appropriate difference between price and cost of high-quality service as social capital’s profit can encourage social capital to provide high-quality service. These policy suggestions will contribute to the sustainable development of social infrastructures in PPP mode.

Abstract In this paper, we study the emergy evaluation index system of the sustainable development of Shenyang Economic and Technological Development Zone (SETDZ) by system dynamics model, and employ the simulation of dynamic evaluation analysis. By the simulation of system dynamics model, four SETDZ’s development scenarios are designed, including inertia scenario, economic scenario, environmental protection scenario and science and technology scenario, and the sustainable development status of each scenario is simulated and dynamically evaluated. The results show that under the background of coordinated development of economy and environment, science and technology scenario based on high-tech investment is the most dynamic, and it also is the best development strategy of SETDZ. Furthermore, SETDZ could achieve the coordinated development of economy and environment by reasonable layout of industrial enterprises, integration of public resources, effective utilization and disposal of waste, establishment of enterprise symbiosis system, development of cleaner production and other measures.

Management Policies

Jiuzhaigou scenic spot (Jiuzhaigou) is an ecological and economic system. The constraints and feedbacks between the economic subsystem and environmental subsystem are very important to the sustainable development. To study this system, the paper creates the system dynamics model about the constraints and feedbacks between economic subsystem and environmental subsystem. The model is made of one growth positive feedback loop of tourism development and two confine positive feedback loops of space constraint and pollution constraint. Then the paper brings up sustainable development management policies in Jiuzhaigou.

The City

A system dynamics model of urban sustainable development is provided, and the impact of different development modes on the city system is explored. Statistical data of Yinchuan, a city in northwest China, is utilized to build the model which shows the population-economy- environment relationship. Four development modes are proposed, and they are maintaining the status quo, developing secondary industry, developing tertiary industry, developing economy and society together. The system dynamics model is employed to analyze the interaction between population, economy and environment. According to simulation of the system dynamics model, impact of development modes on the city system is predicted. Furthermore, suggestions on improving the sustainability of urban development are put forward. In a word, the paper presents a new idea for the study on urban sustainable development in northwest China.
