Industrial transformation and high-quality urban development have become the core issues of urban-rural coordination and the leap forward in development in the new era. The research perspective of 'pattern-process-mechanism' is needed to reveal the spatiotemporal correlation characteristics of industrial transformation and urban economic efficiency evolution, and to expand its systematic, comprehensive and regional characteristics. Based on the geographical cognitive of local effects and spatial non-stationarity, we used a quantile regression model and a geographically weighted regression model to analyze the dynamic mechanism of industrial transformation and urban economic efficiency to explain the path characteristics of urban development and industrial transformation of the Yangtze River economic belt. The conclusions are as follows: (1) From 2000 to 2015, the average economic efficiency in the Yangtze River economic belt increased from 0.05 to 0.332, and the pattern gradually changed from spatial homogeneity to spatial mosaic; (2) From 2000 to 2015, the range and intensity of industrial transformation in the Yangtze River economic belt showed an increasing trend, while the speed of industrial transformation showed a downward trend, and the high-value unit of the three showed the characteristics of gradual homogenization; (3) From the perspective of the impact of industrial transformation on urban economic efficiency, the impact of the range and speed of industrial transformation on urban economic efficiency was gradually weakened, while the impact of the intensity of industrial transformation on urban economic efficiency was gradually strengthened, and the patterns of the three show the characteristics of a spatially inverted U-shaped distribution with high values in the middle reaches and low values in the upstream and downstream areas.
产业转型与高质量城市发展已成为城乡协调和新时代跨越式发展的核心问题。需要采用“模式-过程-机制”的研究视角来揭示产业转型与城市经济效率演变的时空关联特征，并拓展其系统性、全面性和区域性特征。基于局部效应和空间非平稳性的地理认知，我们运用分位数回归模型和地理加权回归模型，分析了产业转型与城市经济效率的动态机制，以解释长江经济带的城市发展和产业转型路径特征。结论如下：（1）2000 年至 2015 年，长江经济带的平均经济效率从 0.05 增加到 0.332，模式逐渐由空间同质性转变为空间镶嵌性；（2）2000 年至 2015 年，长江经济带的产业转型范围和强度呈上升趋势，而产业转型速度呈下降趋势，三者的高值单元呈现出逐渐同质化的特征；（3）从产业转型对城市经济效率的影响来看，产业转型范围和速度对城市经济效率的影响逐渐减弱，而产业转型强度对城市经济效率的影响逐渐增强，三者的模式呈现出中间高、上下游低的空间倒 U 型分布特征。
