Input-Output Analysis on Ecological Footprint of Beijing
利用投入产出技术构建生态足迹模型，计算了2005年北京市的生态承载力，发现总生态足迹需求是土地面积的23倍，人均生态足迹远超生态容量，表明北京发展不可持续。
Ecological Footprint is one of the most important indicators for sustainability measurement.The EF model was built by introducing input-output technique.The paper calculated carrying capacity of Beijing by data of 2005 based on the IO-EF model.The results show that the total requirement of EF is 38538 thousand hm2,almost 23 times of the total land areas of Beijing.Per cap EF is 2.51 hm2,much higher than its ecological capacity.The development of Beijing now is unsustainable.
