Dynamic Analysis on China's Ecological Footprint Supply and Demand from 1978 to 2004

On the basis of the theory of ecological footprint, China's ecological footprint in main years from 1978 to 2004 is analyzed.Depending on the long-term data,the curve of the general demand and supply of ecological footprint is depicted,and the trend of the long-term ecological footprint is observed to judge whether it was in equilibrium.The result is that ecological deficit has been increasing in the long-term.And in the end the ecological consistency of China is analyzed using econometric model.
