摘要
基于单位成本分析模型对2000—2009年西安市大气环境治理的价值量进行了系统核算,并从总量与结构两方面对核算结果进行了深入和全面的分析。结果表明,从西安市历年大气环境的实际治理成本(除2002、2006、2009年)来看,该市在大气环境治理方面的投资基本上逐年增加,但是增加幅度较小,而大气环境虚拟治理成本在一般年份(除2002、2006、2009年)总体上呈现先增加后减小的变化趋势。可见,西安市为改变环境污染状况,不断增加大气环境治理方面的投资,但在初期治理资金缺口仍在增加,而随着投资的持续增加,许多大气环境治理设施的建立与作用的发挥,大气环境污染状况逐渐减轻,治理资金缺口开始变小;在核算年份中,西安市工业大气环境污染治理的重点主要放在了烟尘方面,城镇生活SO2虚拟治理成本在生活废气总虚拟治理成本中所占比例最高。最后,针对发现问题,对该市今后大气环境治理工作的方向和措施给出了建议。
Based on unit cost analysis model,the paper accounts atmospheric environmental treatment costs of Xi’an City from 2000-2009,and analyzes the accounting results from both total amount and cost structure.From the actual atmospheric environmental treatment costs over past years（except 2002,2006,2009）,it could be seen that the investment of Xi’an City on atmospheric environment pollution control was increased gradually within a small range,while the virtual cost for atmospheric environmental treatment presented an increase first then decrease tendency.In order to improve the environment pollution status,Xi’an City has increasing the investment for environment pollution control steadily,however the funding gap for earlier treatment was still increasing;on the other hand,with increasing the investment for environment pollution control,many anti-air pollution installations was established and began to take effect,the environmental air pollution in Xi’an City was reduced gradually,which narrowed the funding gap for environment treatment.In accounting years,Xi’an City has paid more attention on fume treatment in industrial atmospheric environmental pollution control,the virtual SO2 treatment cost account for the largest proportion of total virtual treatment cost of urban life waste gas.Finally,some targeted suggestions were proposed for the problems existed in atmospheric environment pollution control.
