Comprehensive evaluation and impact mechanism of high-quality development of China's resource-based cities

Promoting the transformation, upgrading, and high-quality development of resource-based cities is a key point to achieve high-quality development in China. The comprehensive evaluation of the high-quality development of resource-based cities and the analysis of its influence mechanism can not only enrich the relevant theoretical research, but also have important practical significance. Based on Marxist political economy, this paper reviews and analyzes the theoretical framework of high-quality development in the new era, and systematically constructs the index system of high-quality development of resource-based cities. On this basis, the high-quality development level of 117 resource-based cities is comprehensively estimated, and its influence mechanism is analyzed. The results show the following. (1) From 2005 to 2017, the high-quality development level of resource-based cities continued to grow, showing a significant spatial distribution pattern of "relatively high in the east, but relatively low in the west and northeast". (2) The cities with higher and lower high-quality development levels have obvious regional agglomeration characteristics, but the local imbalance of high-quality development level intensifies, and the phenomenon of spatial polarization continues to expand. (3) The high-quality development level of cities in different growth stages is quite different. Among them, the high-quality development level of regenerative cities is the highest, while that of declining cities is the lowest. (4) The distance between resource-based cities and provincial capital cities or municipalities directly under the central government, natural factors (such as location, and altitude of cities), and the open time of cities have an important impact on the high-quality development level of resource-based cities. © 2021, Science Press.
