Coordinated Development of Energy, Environment and Economic Systems (3E) - Based On a Comparison of Regional Differences

By constructing the 3E symbiosis system model and the 3E system coordination degree evaluation model, this paper measures the coordination degree of 3E system in the three regions of Beijing-Tianjin-Hebei Urban Agglomerations(BTH), Yangtze River Delta Urban Agglomerations(YRD) and Pearl River Delta(PRD). The study found that the 3E system coordination degree in the three regions is in an intermediate coordination state, and the energy system and the environmental system are lagging behind. This paper provides assistance for understanding the coordinated development of China’s 3E system, and provides empirical support for China’s promotion of ecological civilization.
