Since entering the 21th centuっ ら people have been paying more and more attention on green
economy for a better quality oflife and the sustainable development.The two cores of green economy
are conservation of envirolllnent and availability of natural resourcesi the forlner includes controlling

additional emissions,deto対 fying wastes and restorlng en宙 ronmental dalnages;the latter refers topЮ moting

3R(Reduce,Reusc,Recycle)'',Cnhancing fossil… hel e轟 ciency and developing greenenergles.

Govemments are supposed to play ilnpoltant roles in accelerating 3reen eCOnomy in aspects ofproviding cn宙 ronmental in■ astructure and oorrecting market failures caused bypositive or negativcextemalitics".E》 irect regulation,such as quotas,standards,regulations or la、 vs,whiCh is referred to asà(command― oontrol"approacL has been the primary instrumellt in most countries.Economic
incent市 e,such as taxes and subsidies,which is the price― based"叩 proaCh,is thought as a more cost―efflcient way to encourage cnvirorllnental liabilities by making fun use ofrnarket rnechanism.

There are many theoretical and empirical studies on green economy,having provided quite a few
valuable suggestions for policymakers.However,some studics are too oonising to be understood andsomewhat remote from reality.
This paper gives basic and essential econonlic interpretations on hovF to promote 3TCen economy
and provides a ttndamental■ amework for economic studies on designing 8reen policics.NIIoreover,it

proposes a new theory of̀̀pollution abatement stages model''so as to explain how to improve
envirolllnental quality in a more effective and efflcient way.For an intuitive understanding,we use
more graphs instead ofcomplicated mathematical equations to demonstrate ideas and the new tlleow.

2.D市 ersity of en宙 ronmental problems with the economic growth
There are a great variety of envirollmental problems, and their solutions and corresponding
nmentalabatement costs vary with respect市 e types.Therefore,it is hard to build a complex enviЮ
indicator to evaluate the quality ofen宙 ronment orthe effect ofen宙 ronmental policies.

Figure l shows that environmental problems can be 3Tasped from three dimensions: Time‐dimension(ShOrt→ long― secular), Space… dimension(communal→ regionaVnational― >global)andRange― dimension(indi宙 dual… →sectoral― )oommon).There are many combinations for describing
various types ofenvlonmental problems.Type A(shottICOmmunal+indi宙 dual,suchぉ nei3hbOrhoodnoise)and type B(Seculttglobal+oommon,such as global warlning)are tlle two extremes.With theup3rading from A to B,the problem becomes more and more seHous and hard lo be solved.Industrial
Юlllmental pЮ blem which
pollution(10ng+communa1/regional+sectoral)is the mOtt familiar en宙always happens in the local area, so it is easier to point polluters.()n the other hand, agricultural
pollution is a non― point source ponution and trans‐ regional and thus very intractable.
