This　paper　systematically　analyzed　the　imbalance　between　economic　development　and　ecological　environmental　protection　in　provinces　of　China.　A　coordination　degree　evaluation　method　based　on　comprehensive　economic　index　and　comprehensive　environmental　index　has　been　established　and　used　to　assess　the　coordinated　development　at　three　levels.　The　results　showed:　1)　for　all　China＇s　31　provinces,　the　environmental　conditions　have　been　lagging　behind　the　regional　economic　development.　2)　The　overall　level　of　economic　development　and　urbanization　of　most　provinces　were　relatively　high,　average　scores　of　indicators　on　GDP　per　capita,　population　urbanization,　disposable　income　of　urban　residents　were　0.6388,　0.8207,　0.9664,　respectively.　3)　Pressures　on　deepening　reform　and　expanding　opening,　and　the　gap　between　urban　and　rural　development　were　main　factors　that　led　to　the　uncoordinated　development　of　regional　economy.　4)　Most　provinces　made　good　performance　in　urban　environmental　management　and　air　pollution　control,　but　low　investment　in　industrial　pollution　control　and　undesirable　aquatic　ecological　environment　were　still　major　obstacles　to　coordinated　development　of　economy-environment　system.
