西部资源型城市绿色发展效率时空分异与驱动力

绿色发展是资源型城市高质量转型的重要体现。通过构建绿色发展效率评价体系，基于MinDs模型、泰尔指数、地理探测器等方法，测算2001—2019年西部资源型城市绿色发展效率时空分异特征，分析其驱动因素。结论如下：（1）西部资源型城市绿色发展效率以2015年为界，呈“先升后降”变化，西北、广西的资源型城市整体上升，西南和内蒙古的资源型城市近年呈下降趋势，成长型城市发展较为稳定，成熟型和再生型城市2017年后下降明显，衰退型城市呈上升趋势；（2）西部资源型城市绿色发展效率表现为极低和极高区间数量少、中间得分数量多的正态分布特征；（3）绿色发展效率空间非均衡的问题较为严重，其中，西北与西南地区的成熟型城市的变化是导致绿色发展效率差异扩大的主要原因；（4）经济发展、城市化、城市规模和技术创新能够显著提升西部资源型城市绿色发展效率，不同空间范围和不同生命周期下的资源型城市绿色发展效率驱动因素各有特点。研究对提升西部各类资源型城市绿色发展效率有实际意义。

Research on spatiotemporal heterogeneity and driving forces of green development efficiency in resource-based cities of Western China

Green development is an important manifestation of the high-quality transformation of resource-based cities. The study develops a green development efficiency evaluation system, using MinDs model, Theil index, Geodetector and other methods, to measure green development efficiencies in resource-based cities of Western China from 2001 to 2019, and analyzes the spatiotemporal heterogeneity characteristics and associated driving factors. The main conclusions are as follows: (1) The green development efficiency of resource-based cities in the western region is bounded by 2015, showing a trend of "rising first and then falling", the green development efficiency change trends of different types of cities are quite different, resource-based cities in Northwest China and Guangxi have shown an upward trend as a whole, resource-based cities in Southwest China and Inner Mongolia have shown a downward trend in recent years, growing cities have developed relatively stable, mature and regenerating cities have declined significantly after 2017, and declining cities have shown an upward trend. (2) The green development efficiency of resource-based cities in the western region is characterized by a normal distribution with a small number of extremely low and extremely high intervals, and a large number of intermediate scores. (3) The problem of spatial unevenness of green development efficiency is still serious. Changes in the efficiencies of mature cities in northwest and southwest regions are the dominant factors for expanding gaps in the efficiencies of resource-based cities in Western China. (4) Economic development, urbanization, city size expansion and technological innovation can significantly increase the green development efficiency of resource-based cities in the whole study area. Moreover, the driving factors of green development efficiency of resource-based cities in different spatial ranges and different life cycles have their own characteristics. The research has practical significance for improving the green development efficiency of various resource-based cities in the western region of China.
