its forms , Sectoral distributions. The study aims also to estimate the relationship between private investment and a list of factors such as ( Gross Domestic Product , interest rate , government spending, money supply and taxes ).
To achieve this aim the study applied the method of Vector Auto Regression (VAR).
The study also conduct many tests which include :

the results of the study revealed that gross domestic product government spending , money supply and interest rate are Stationary at level. while the private investment is not stable at level but stable at first difference , also direct tax is not stable at level but stable at second difference.
The" Granger" test of causality showed that :
1) there was bidirectional relationship between investment and money supply, that mean each on cause the other .
2) there was unidirectional relationship from interest rate to investment.
3) there was unidirectional relationship from investment to direct taxes .
