文章采用因子分析分析方法对广西1978~2008年环境脆弱性进行测度,然后运用格兰杰因果分析方法分别对广西总体经济增长、第一、二、三产业与广西环境脆弱性进行因果分析,通过滞后期的选择,从而判定他们之间的因果信息及其形成特征.结果显示:经济增长与环境脆弱之间是否存在格兰杰因果关系,存在产业差异,并在很大程度上受到滞后期数的影响,而且经济增长与环境脆弱之间的因果关系,并且在方向上也存在着差异.“,”This paper describes the development of Guangxi's economic development.By building up Guangxi' s environmental index system and using factor analysis,it measures the environmental fragility in the period of 1978~2008 and analyzes the evolution of the environment in Guangxi.Then,by using Granger causality analysis,the paper makes a causal analysis to determine whether the causal relationships exist respectively between the environmental fragility and the overall economic growth,the primary industry,secondary industry,industry,construction,the tertiary industry,transport storage and communication industry,wholesale and retail trade and catering industry in Guangxi.The results show:between economic growth and environmental fragility Granger causal relationship exists,which is different between industries and be shaped largely by the delay,and the causal relationship between economic growth and environmental fragility is also different in direction.
