甘肃省城市化与生态环境关系的计量分析

结合甘肃省的统计数据,采用计量经济学的方法来分析甘肃省城市化与生态环境变化之间的关系,发现甘肃省城市化进程缓慢,各个环境压力要素和城市化耦合的规律与特征相关性高,耦合曲线呈现出"U"型或直线型规律,还表现出阶段性特征,而不是倒"U"型。因此可以说,只有广义技术进步的速度达到或超过经济总量增长速度时,城市化与环境压力要素耦合的倒"U"型曲线才可能形成。

Measurement Analysis of Relationship between Urbanization and Ecological Environment of Gansu Province

Taking Gansu Province's statistical data as the support,this paper analyzes the dynamic relationship between urbanization and the ecological environment by the econometrics method.The research discovers that Gansu Province' urbanization advancement is slow.The relevance of each environment pressure essential factor the rule of urbanized coupling and the characteristic are high,and the coupling curve presents "U"-shape or the straight line,also displays stage characteristics,but is not inverse"U"-shape.It is obtainedas the conclusion that when the generalized technology advancement speed achieves GDP growth,the coupling inverse "U" curve of urbanization and environment pressure essential factor may form.
