Abstract: Industrial ecologization is an important issue in the ecological civilization construction and highquality development. Understanding of the spatialtemporal evolution characteristics of industrial ecologization and its influencing factors can provide insights into watershed ecological protection and highquality development. In this study, we established a comprehensive evaluation index system of industrial ecologization from two dimensions, i.e., industrial system and ecosystem, and quantitatively measured the levels of industrial ecologization of nine provinces in the Yellow River Basin from 2005 to 2019 by using the entropy method, the coupling coordination model, the Theil index, and the Tobit regression model. The evolution characteristics of spatialtemporal pattern of industrial ecologization level were expounded, and the influencing factors were explored. The results showed that: (1) The industrial ecologization level of nine provinces generally showed an upward trend with significant spatial differentiation characteristics, and exhibited a spatial pattern of “strong in the east and weak in the west”. Specifically, the development level of downstream area was higher and growth rate was faster, while in the upstream area, especially in Qinghai and Gansu provinces, the process of industrial ecologization significantly lagged the other provinces, and the gap continued to expand. (2) The industrial system and ecosystem in various provinces had gradually developed from imbalance to the coordination, but the development rate had been slowed down, indicating that the coupling coordination degree should be further improved. (3) The coupling coordination degree of industrial ecologization differed greatly among these provinces, but the difference showed a decreasing trend over time. It is urgently needed to establish an ecological-economic system with industrial ecologization and ecological industrialization as the main body to promote the ecological protection and high-quality development of the Yellow River Basin. (4) There was a significant “U-shaped” relationship between economic development and industrial ecologization, in which the cleaner production and the degree of marketization play a positive role in improving industrial ecologization, while the end of pipe control and fiscal decentralization play a negative role, and the effect of industrial agglomeration is not obvious.
