Abstract: Based on the statistical and satellite remote sensing data of 57 regions in Liaoning Province from 2006 to 2015a， the spatial Durbin model was used to test the spatial effect of government and market environment regulation tools on the decoupling of industrial development and haze in the neighboring regions. The results of spatial autocorrelation showed that haze decoupling in Liaoning Province presents a spatial positive correlation， and most of the regions are absolutely and relatively decoupled. The empirical results show that due to the low resource tax cost and effective supervision of local governments on the environmental responsibility of large enterprises， the government′s environmental regulation effect is better than the market environmental regulation; the demonstration effect and atmospheric movement have brought positive guidance and ripple effects to the neighboring regions.

Key words: environmental regulation, haze pollution, decoupling, spatial correlation, spatial Durbin model
