By using the entropy method and the coupling assessment model, this paper constructs the comprehensive evaluation index system of industrial ecology in Guangzhou from two dimensions, i.e., the economic efficiency and ecological efficiency. Then it explores the spatial and temporal evolution of the industrial ecology in Guangzhou from 2005 to 2015, and analyzes the coordinative evolution of the economic efficiency and ecological efficiency, as well as its driving forces. The results show that: (1) According to the temporal evolution characteristics, the industrial ecological development in Guangzhou continues to improve on the whole despite of some fluctuations, with the improvement rate of ecological efficiency higher than that of economic efficiency. (2) In terms of spatial distribution, the industrial ecological development presents the distribution pattern featured by the decreasing level from the core area to the main urban area and further to the peripheral area. From the perspective of spatial evolution, the overall level difference among regions has become smaller, which remained a relatively stable distribution pattern. (3) The overall coordination degree between economic efficiency and ecological efficiency in Guangzhou is rising steadily. The level of the coordination type shows the trend of gradual improvement from the peripheral area to the core area. The evolution mode of coordination type can be divided into three types: coordinated deepening development, coordinated development and professional development. (4) Industrial development strategy, urban spatial development strategy, environmental supervision, technological innovation and application, as well as enterprises' awareness of energy conservation and emission reduction, are the important driving forces for the development of industrial ecology in Guangzhou.
