Urban green land use efficiency of resource-based cities in China: Multidimensional measurements, spatial-temporal changes, and driving factors

Abstract

The green use of urban land has become a key for the sustainable transformation of resource-based cities. This paper selects 116 Chinese resource-based cities to construct an evaluation system for urban green land use and measure its efficiency. Secondly, it identifies driving factors affecting urban green land use efficiency (UGLUE) and comprehensively analyze the heterogeneity of these factors. The important findings of this paper include: (1) The UGLUE of resource-based cities in China has experienced a trend of first fluctuating and then improving. However, there are obvious regional differences. The UGLUE in the eastern and western regions are higher than those in the central and northeastern regions. (2) Industrial upgrading, financial development and technological innovation are key factors affecting UGLUE in resource-based cities. (3) There is significant heterogeneity in the impact of different factors in different city types, different regions and different time periods. The land use in resource-based cities should transform from blind expansion in pursuit of short-term economic benefits to a green development that pursues the coordination of economic, social, and ecological benefits based on the local conditions.
