文章信息 题目： Air pollution in heterogenous Chinese cities: complex network, novel driver and dec oupling nexus 作者：徐冲， 李军 ，陈建东 * ，杨倩 期刊： Ecological Indicators 详细： 1 56 ， 111077 ， 2023 年 10 月 DOI ： 10.1016/j.ecolind.20 23.111077 文章摘要 T he study contributed to the existing researches by depicting the complex network and efficiency-related drivers of PM 2.5 concentration, and by proposing two production-theoretical decomposition analysis (PDA) -based spatiotemporal decoupling models that incorporate efficiency-related factors in spatiotemporal decoupling analysis for the first time. We comprehensively used social network analysis, extended PDA and the proposed spatiotemporal decoupling models, to investigate the network and driver PM 2.5 concentrations as well as the decoupling nexus with fiscal environmental expenditure ( FEE ) in a case of Chinese cities classified by population size and economic structure over
