help to panel estimation result

[wolly77]

Hi guys. I'm new in estimation with panel data (I worked with time series for years). I estimates an unbalanced panel data with TSLS. The result of this output is the following reported below. Anyone can help me to suggest me which kind of tests are needed to justify this result? In the "panel option" I have to select some options in particular (for example effect specification (fixed or random), GLS weights, Coef covariance method (ordinary, white cross section, white period, etc.))?

I send you also a copy of my work file in eviews (the equation estimated is called "EQ_TSLS"). Thanks in advance.
