财政收入和财政支出的关系图:新建w orkfile,注意开始日期和截止日期: 把数据载入workfile 中,取名:f_ex 和 f_in
把两个变量作为一个组打开,点击view/garph 画图,直接点击ok
单位根检验表面:财政支出和财政收入都是一阶单整,可以探讨两者的协整关系
具体操作步骤: 先单独打开f_ex,点击view/unit root test
然后点击ok
接下来,要再次重复这个动作,只是选项中药选择1 st difference
如下图所示点击ok
单位根检验如下表: Null Hypothesis: F_EX has a unit root Exogenous: Constant Lag Length: 11 (Automatic - based on SIC, maxlag=14) t-Statistic Prob
