Abstract：This study analyzes the space-time evolution trend of green technology innovation in Chengdu-Chongqing economic circle from 2006 to 2019 by constructing the evaluation index system, which combines with SNA method and SARAR model to reveal the network structure characteristics and effects of spatial correlation of green technology innovation. The results show that: the level of green technology innovation in the economic circle fluctuates and rises, and the spatial “radiation effect” is gradually highlighted. The network structure of green technology innovation has changed from “dual-core” to “multi-core，” and the spatial network has become closer and more stable. Chengdu and Chongqing are at the core of the network and are the main spillover cities and central actors; Deyang, Mianyang，and Yibin mainly play the role of “bridge” and “intermediary.” The economic circle is closely connected between plates, and the spatial spillover of green technology innovation is mainly intra plate spillover. The overall network density and the centrality of urban nodes have significantly improved the level of urban green technology innovation, and the positive effect of proximity to centrality is the most prominent.
