摘要
首先对我国1978—2007年间的生态足迹进行了测算,然后对城市化与生态足迹进行单位根检验及协整检验,最后建立向量自回归模型,利用广义脉冲响应函数法对其关系进行了实证分析。研究结果表明,我国的快速城市化导致生态足迹的增加,即生态环境的恶化。
Firstly,the ecological footprint of China between 1978 and 2007 is calculated.Then,unit root test and cointegration test of urbanization and ecological footprint are conducted. Finally, VAR model are established and generalized impulse response function are applied to describe the correlation. The results show that the rapid urbanization increases the ecological footprint, which means deterioration of ecological environment.
