This　research　establishes　a　set　of　multi-layer　comprehensive　evaluation　index　system　through　global　entropy　method　and　conducts　comprehensive　evaluation　of　the　environmental　planning　intensity　among　Chinese　provincial　governments.　Based　on　the　above,　the　inter-regional　differences　in　environmental　regulation　intensity　among　30　Chinese　provincial　governments　are　further　analysed　with　methods　of　quartile　analysis　and　coefficient　of　variance,　revealing　the　status　of　spatial　differences　in　environmental　regulation　level　among　provincial　governments.　In　addition,　corresponding　overall　planning　countermeasures　are　proposed.　Research　results　show　that　during　2006-2014,　the　environmental　regulation　intensity　of　various　Chinese　provincial　governments　had　all　seen　certain　improvement,　but　the　inter-regional　differences　tended　to　be　widening　after　experiencing　certain　amplitude　of　narrowing;　and　there　was　obvious　difference　in　cognition　of　the　importance　of　environmental　governance　investment　among　different　provincial　regions.　To　promote　synergistic　advancement　of　environmental　regulation　in　Chinese　provincial　governments,　the　environmental　regulation　cooperation　mechanism　for　cross-administrative　regions　has　to　be　perfected,　scientific　and　reasonable　regional　government　performance　examination　mechanism　has　to　be　established,　and　muti-subject　synergistic　governance　mechanism　has　to　be　set　up　as　well.　©　2019　Technoscience　Publications.　All　Rights　Reserved.
