Introduction: One of The most important exchange resource in country has been oil revenues. So, the examination effect of incomes obtained by oil revenues on society welfare seems important and necessary.

Method: by using of stoical data during 1347-1388 and Vector Outo Regression method, the relationship between social welfare and oil revenues has been examined. Data was gathered by EVIEWS6 software.

Finding: we see less effect of national income on welfare. Non-oil revenues have a negative effect on welfare in longterm. Also, oil revenues have a positive effect on welfare in short term but this positive effect decreased in longterm.

Discussion: Since national income can be a good indicatore to increase of social welfare, more attention to distribution oil revenues between society people would be nice. Non-oil revenues also can have a positive effect on welfare by tax system.
