摘要
基于1990—2012年北京GDP数据和三次产业用水量数据,进行GDP数据与三次产业用水量的平稳性检验和协整检验,检验通过后,对四组数据构建SVAR模型,利用脉冲响应函数,分析北京GDP与三次产业用水量之间的相互关系,结果显示第一产业用水量、第二产业用水量与北京GDP的增长负相关,第三产业用水量与北京GDP的增长正相关.
Based on the various data（annual data from 1990-2012） that the research required,the GDP,the primary industry water consumption（AW）,the secondary industry water consumption（PW）,the tertiary industry water consumption（TW）,the stationary test and co-integration test were used to analyze the data. Then we constructed the Structural Vector Autoregression model（SVAR） of the GDP , AW , PW , TW . We analyzed the relationships among GDP and AW,PW,TW,with the impulse response function. The results shows that AW and PW are negatively correlated with GDP,and the TW is positively correlated with GDP.
