st:what if no data is available at all

I would like to run panel regression using firm level annual data such that
The problem here is that I have no data for x1(firm level),thus I instead,
tried to regress x1 on related variables using "industry level" data and use
the fitted values to generate x1.

More specifically,

  1st step: run X1=b0+b1*Z1+b2*Z2+... and find out fitted values of all b's (X1
and all Z's are industry level data, but not annually )

 2nd step: using fitted value b's and firm level data,
find out x1 such that x1=b0hat + b1hat*z1+b2hat*z2
(all z's are firm level annual data,  )

 3rd step: run first regression.

It look like generating proxy var. for x1.
I would like to know if anything wrong this approach under the case that there
exist no data or if there are better suggestions.
