中国区域大气环境承载力DEA评价

Evaluation of air environment carrying capacity based on DEA in China

将数据包络分析(DEA)模型引入大气环境承载力研究中,选取27个有代表性的省级行政区,以火电、钢铁、水泥3个重点行业,利用2009年统计数据,分析了这27个省(区)市的现状承载力、承载潜力和经济布局优化方案.结果表明,基于DEA模型的大气环境承载力评价结果,可将27个省(区)市分为3类区域,其中,第1和第2类型区潜力较大,应作为经济发展布局的重点区域;经济布局优化方案对于区域大气环境的承载潜力、地区经济发展潜力有较强的指导作用.

DEA approach was applied to evaluate the air environment carrying capacity by using 27 provinces and 3 main industries as samples to analyze the present situation, potential and optimization of carrying capacity of air environment. The results show that the 27 provinces could be divided into three groups. The first two groups have more potential of air environment capacity to carry industry development
