Decoupling analysis and rebound effect between China's urban innovation capability and resource consumption

Based on the improved Tapio decoupling model and geographic information system spatial analysis technology, this paper studied the spatial and temporal pattern evolution law of the decoupling relationship between innovation capability and resource consumption in 283 cities in China. The non-residual complete decomposition model was used to decompose the rebound effect of resource consumption in China's urban innovation development. We found (1) during the study period, innovation capability and resource consumption in Chinese cities showed a weak decoupling state. (2) Regions with significant decoupling showed a trend of spatial agglomeration, and the gap in the degree of urban decoupling gradually narrowed. (3) The increase in urban population growth and innovation intensity in China have a positive pull effect on resource consumption. The improvement in resource efficiency has an inhibitory effect on resource consumption, but this inhibition is less than the effect of population scale and innovation intensity on resource consumption.
