Based on prefecture-level panel data and social media big data, this paper investigates how industrial agglomeration, environmental regulations and technology affect intensity and spillover channels of pollutant emission by integrating social and economic networks into Spatial Durbin Models. The results from econometric models show that industrial agglomeration, environmental regulations and technology input facilitate environmental emission intensity abatement. The results also confirm the different spillover channels through which these factors affect urban pollutant emissions with different network relations. Agglomeration has negative spillover effects on pollutant emissions in cities within social media and spatial networks. Environmental regulations also affect pollutant emissions in related cities through social networks. We also find the technology can effectively lower the pollutant emission through economic network channels. The findings highlight the network linkages and spillover channels during the pollutant treatment.
