OLS or 2SLS to run the data

[sy chia]

Dear all,

May anyone can help to answer if i have 2 model as below which is:
model 1- dependent var is time series data and independent var is both time series and cross sectional data
model 2-dependent var and independent var are both time series and cross sectional data

Model 1- CR t = PROFITit + ASSET it + GDP t
Model 2- PROFIT it = CR t +ASSET it + GDP t
May i know the 2 model as above consider as panel data or not since model 1 the dependent var is time series data?
And is it possible to run 2sls by using STATA with command ivreg2?
