摘　　要：采用PSR模型构建重庆市大气污染治理政策效果评价指标体系,通过熵权法与综合指数法对政策效果综合评价,并引进障碍度模型进行障碍因子判断。结果表明,重庆市大气污染治理政策效果显著提升,大气环境质量得到明显改善,压力、状态、响应层面总体上取得了较满意的效果;工业废气排放持续有效控制尚需加强和人均机动车保有量持续增加,NO_(2)、O_(3)污染物排放控制力度需要加强;缺乏较为完善的大气环境污染协同防治体系,是制约重庆市大气污染治理政策效果的重要障碍因素。因此,加强工业氮氧化物和挥发性有机物的深度治理、加强新生产和在用汽车排放管理和完善“政-企-民”协同防治体系,是进一步提升大气污染治理政策效果主要着力点。This article used pressure-state-response(PSR)model to construct an index system for evaluating the effects of air pollution control policies in Chongqing,China.The entropy weight method and the aggregative index method were adopted to provide a comprehensive evaluation of policies’effects,and obstacle degree model was used as well to determine obstruction factor.It has concluded as follows:the effectiveness of Chongqing's air pollution control policies has been significantly improved.The quality of the atmospheric environment has been greatly improved.At aspects of pressure,state,and response,in general,it has achieved a relatively satisfactory effect.It remained necessary to strengthen the effective control of industrial exhaust emissions and NO_(2) and O_(3) pollutants emissions.Per capita motor vehicle ownership continued to rise.An important factor that constrained the effectiveness of Chongqing's air pollution control policies was the lack of a comprehensive system for control and prevention of air environmental pollution.To summarize,the focus of further enhancing the effectiveness of air pollution control policies is to strengthen the in-depth control of industrial nitrogen oxides and volatile organic compounds,to intensify the management of emissions from newly produced and in-use vehicles,and to improve the"government-business-citizen"collaborative prevention and control system.
