Univariate linear regression mainly studies the linear correlation between two variables. This article mainly selects Shandong Province’s total social fixed asset investment and regional gross product (GDP) as variables to explore the relationship between the two from 1975 to 2017, and performs a regression analysis. The results show that there is a positive correlation between the two, and Shandong Province’s whole-society fixed asset investment has a positive prediction effect on Shandong Province’s GDP.
