Inclusive green growth for sustainable development of cities in China: spatiotemporal differences and influencing factors.

Inclusive green growth (IGG) based on coordinating the society, economy, and environment is a new way to reach sustainable development. However, there is a lack of relevant research in developing countries. To bridge this gap, based on a comprehensive index that includes economy, social, and environment, this study evaluates the urban inclusive green growth index (IGGI) of 282 in China from 2003 to 2020 and analyzes the spatiotemporal dynamics and regional differences. Moreover, the spatial Durbin model is employed to explore the plausible influencing factors of urban IGGI in China. The main results show an increasing trend of IGGI in Chinese cities and imbalanced spatiotemporal dynamics. Furthermore, the econometric regress results show that upgrade of industrial structure, opening up, human capital, and urban innovation have significant positive impact on urban IGGI, while the administrative capacity of the government and urban industrialization show negative impact on urban IGGI; human capital not only affects the local IGGI but also has significant spatial spillover effects to the surrounding cities. This finding provides new evidence for China to achieve its 2030 sustainable development goals and sheds lights on how policy can be improved to boost IGGI levels and achieve carbon neutrality in 2060.
