Abstract:

By compiling a social accounting matrix containing environmental accounts of Jiangxi Province in 2002,we estimated impacts of different schemes of the nitrogen and phosphorus reduction on the output value of 18 sectors,which included collecting discharge fees,subsidizing emission reduction of nitrogen and subsidizing emission reduction of phosphorus.The research result indicated that different schemes had different marginal impacts on the output value of the sectors.The adjustment of criteria of fees for nitrogen and phosphorus emission had marginal impacts on the values of sectors on the whole.There was little change in the values of sectors except the tertiary sector,and the less nitrogen and phosphorus the sector discharged,the more its output value changed.However,adjustment of criteria of subsidies for emission reduction of nitrogen and phosphorus turned out to be on the contrary;the more nitrogen and phosphorus the sector discharged,the more its output value increased.It can be seen that subsidy on the emission reduction of phosphorus bears more apparent effects on the changes of output values of sectors from that of the regulation measures
