Comprehensive carrying capacity, economic growth and the sustainable development of urban areas: A case study of the Yangtze River Economic Belt

Abstract

Abstract The sustainable development of a city should occur via the harmonious development of the urban comprehensive carrying capacity (UCC) and economic growth. To study the 84 cities in the Yangtze River Economic Belt (YREB) from 2006 to 2014, this paper uses a spatial econometrics model to evaluate the relationship between the UCC and economic growth, and explore the sustainability of urban development. The results infer some novel findings. First, the impact of economic growth on the UCC has inverted “U”-type characteristics. The economic growth pattern of the urban agglomeration weakens the UCC. Second, the impact of the UCC on economic growth has “U”-type characteristics. The development of the UCC plays a significant supporting role in the economic growth of the YREB. In 2014, 84 cities stayed in the descending phase of the inverted “U” curve, and approximately 50 cities of them lied on the rising segment of the “U” curve. Therefore, reconstructing economic growth models to enhance the UCC represents an important method of realizing a city's sustainable development.
