Study on Urban Sustainable Development Based on System Dynamics

Abstract

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.

Developing a Dynamic Model for Assessing Green Infrastructure Investments in Urban Areas

“…Although the development of a dynamic model of a city is not an entirely novel idea [25,[32][33][34][35], the idea of using it to study the effects of investment on green infrastructure, as a solution to the environmental threats that cities face today, is a more recent approach, which is not sufficiently settled in the literature [24,[36][37][38]. For this purpose, in this study, a cost-benefit analysis of investment nature-based solutions has been carried out, as well as the implementation of new environmental policies (i.e., reduction of pollutant emissions, waste management, etc.…”
