Macroeconomic variable combined with firm specific variable

[darren]

Hi guys. I am currently doing a research on the factors affecting 8 banks' credit risk from 2010 to 2018. For the independent variables, my model consists of macroeconomic variables (X1= GDP. X2= interest rate) and bank-specific variables (X3=ROE. X4=ROA,X5=liquidity ratio). Can I use fixed effect model to find its regression?
