基于两型社会研究的长株潭大气污染经济损失估算

Economic loss assessment caused by air pollution of Changsha-Zhuzhou-Xiangtan two type society

基于"两型社会"资源节约、环境友好的两条主线,对大气污染的经济损失估算方法和模式进行了研究。在对"长株潭城市群"地区大气污染资料调查和统计的基础上,结合该地区的实际情况,应用环境经济学的原理与方法(修正人力资本法、市场价值法、机会成本法、资产价值法等),从多个方面综合考虑并建立模型,估算了长株潭地区大气污染造成的对经济损失,并对大气污染造成的生态损失进行了分析。结果表明,2007年长株潭地区由大气污染造成的最低经济损失保守估算为35.66亿元,占当年GDP的1.03%,而2007年用于治理大气污染的投资只占该地区GDP的0.2%,投资力度明显不足,两型社会的建设仍有很多工作亟待进行。

Based on the resource-saving and environment-friendly society,the economic loss caused by air pollution of Changsha-Zhuzhou-Xiangtan Urban Agglomeration was estimated. According to the air pollution statistics and investiga-tion of Changsha-Zhuzhou-Xiangtan Urban Agglomeration,a comprehensive model,which based on Environmental Eco-nomics,was established with corrected human capital method,market value method,opportunity cost approach and asset value method,etc. The economic losses and ecological damage caused by air pollution were calculated. The results show that the lowest economic loss caused by air pollution of Changsha-Zhuzhou-Xiangtan Urban Agglomeration is 3.566 bil-lion in 2007,which accounts for 1.03 percent of GDP of that year. But the investment to controlling air pollution of that year only accounts for 0.2 percent of GDP,which is obviously inadequate.
