Regional sustainability system as ecosystem: case study of China’s two leading economic circles from a keystone perspective

摘要: Exploring the structure, function, and dynamics of regional sustainability system (as ecosystem) can help providing insights into importance how environmental management answers to socioeconomic changes for transitioning sustainable development. The connectivity (structure) stability (function) are investigated through making radiation capability model spatial coordination index model, which is relied on keystone province influences other provinces from society, economy environment dimensions. brand new models then applied two largest urban agglomerations in China during period 2001–2014. results show that BHR distinctly weaker than YRD, reveal essential characteristics underlying drivers system. To be specific, initially, it reflects whole harbors larger difference lower YRD. Additionally, YRD has much higher better interactive function BHR. Thirdly, although development level both increases at a certain speed year by year, disparity among various shows an apparent decline contribution mainly comes intra-BHR. Finally, also provides key surrounding interact what main contributors are. Overall, taking as ecosystem well this complex provide references any worldwide.
