Simulation of pollutant control cost and its economic impact based on China's green input-output table
The direct pollution generation coefficient and complete generation coefficient of wastewater,air pollutants and solid waste were analyzed,based on the China's green input-output table.Furthermore,the pollutant control cost and its economic impact were simulated.Some results are shown as follows.(1) The complete generation coefficient of certain industries,such as production and supply of electric power and heat power,manufacture of raw chemical materials and chemical products,smelting and pressing of ferrous metals,processing of petroleum and coking,extraction of petroleum and natural gas,was higher than that of other industries,and the industries should be taken as main regulatory targets.(2) The simulated control cost of wastewater was 6.4 yuan/t,the control cost of air pollutants was 2136 yuan/t,and the control cost of solid waste was 101 yuan/t.In comparison,the actual cost of wastewater was 3 yuan/t,the actual control cost of air pollutants was 305 yuan/t,and the actual control cost of solid waste was 30 yuan/t in 2007.The simulated control cost was 2.1 times,2.4 times and 2 times the actual cost.(3) If simulated pollutant control costs were imposed,the prices of certain industries would be impacted heavily and the prices change of certain industries were higher than 10％,such as production and supply of electric power and heat power,mining and processing of non-ferrous metal ores,mining and processing of ferrous metal ores,manufacture of paper and paper products,smelting and pressing of non-ferrous metals,smelting and pressing of ferrous metals,manufacture of non-metallic mineral products.(4) It is not feasible that the cost of environmental pollution control entirely was undertaken by the enterprises from the simulation results.On one hand,government controls environmental pollution through collection of sewage charges or emissions trading.On the other hand,environmental pollution should be treated by intensive treatment to play investment benefit and scale economic effect.Thus,"Those that make pollution should pay for its cost" could bring more benefits than "Those who make pollution should control it".
