Spatial and temporal evolution of urban economic development efficiency in China’s Yangtze River economic belt from the perspective of sustainable development

Abstract: Urban economic development is crucial to regional economy and people’s life, and enhancing the efficiency of urban economic development is of great significance to boost sustainable and healthy economic and social development. In this paper, from the perspective of sustainable development, data of 104 cities in China’s Yangtze River Economic Belt (YREB) from 2004 to 2019 are selected, and the urban resource consumption index and urban pollutant emission index are synthesized as new input-output indicators usin… Show more

“…It is based on parameters such as the centre of gravity, azimuthal angle θ, and long and short axes of the ellipse to determine the centre of gravity, direction and evolutionary law of the spatio-temporal development of the research object. It reflects the degree of dispersion of the research object in space and determines the direction of distribution of its spatio-temporal development and the trajectory of migration of the centre of gravity [ 59 , 60 ]: …”

“…For instance, the Yangtze River Economic Belt covers 11 provinces and municipalities, including Shanghai, Jiangsu, Zhejiang, Anhui, Jiangxi, Hubei, Hunan, Chongqing, Sichuan, Yunnan, and Guizhou, with an area of approximately 2,052,300 square kilometers, and accounting for 21.4% of China's population and more than 40% of China's total GDP (He et al, 2022). This belt has important policy effects (Yao et al, 2022). To consider this, we divided the 31 sample provinces into two groups: the Yangtze River Economic Belt and the non-Yangtze River Economic Belt.…”
