“…The reason for this is that NU is urbanization with urban-rural integration, industrial interaction, conservation and intensification, ecological livability, and harmonious development as its basic features and therefore is conducive to enhancing the capacity of urban environmental regulation [110,111], promoting the green transformation of industries [112], improving the capacity of urban resource utilization [113,114], and optimizing the spatial structure of the city [115], which in turn reduces the input resources for urban operation, enhances the performance outputs of urban operation, and ultimately improves the UME [116]. At the same time, the findings of this study provide China's answer to the real-life dilemma of "how to urbanize with the goal of sustainable urban development in mind", which is faced by many countries [117][118][119], and will help countries and alliances such as the Caribbean region [120], UNESCO biosphere reserves [121], Singapore [16], India [122], and Australia [123] to better address sustainable development in the process of urbanization.…”
