Influencing factor and path research on the high-quality development of the urban mining industry

Abstract

The recycling of urban mining is one of the means to alleviate resource bottlenecks and build an ecological industrial system in China. To study the characteristics of high-quality development of the urban mining industry, the high-quality development capacity of this industry from 2006 to 2020 is evaluated based on the entropy weighting – catastrophe progression method, and its development pattern and influencing factors are discussed. The analysis results show that: ①The high-quality development capacity of the urban mining industry declines slowly, with an average annual decline of about 0.399% from 2006 to 2020, and the overall development quality level is on average. The provinces with high-quality development are scattered from the east region of the Hu Line to the north and south regions, and non-high-quality development provinces are contiguous. ②The positive spatial correlation of the urban mining industry is significant, but the agglomeration degree in high-quality development provinces is low-high-low. According to the spatial agglomeration characteristics, the high-quality development pattern is divided into five zones. ③Among the factors driving the high-quality development of the urban mining industry, regional GDP per capita, R&D investment, the number of patent applications granted and Internet penetration rate are the core influencing factors. High-quality sustainable zone and high-quality restoration zone need to rely on the number of granted patent applications to achieve high-quality maintenance and restoration, high-quality compensation zone and high-quality stability maintenance zone need GDP per capita and R&D investment, high-quality development zone relies on Internet penetration rate to explore high-quality development potential.
