遇到同样的问题 在外网上查到的：供参考

Typically, when you do something like that you are trying
to manually recreate a fixed effects regression. If that is
what you want to do, then you should not use -regress- but
-xtreg- instead, see -help xtreg-.

There is no way to suppress part of the output, but you can
suppress the entire output and later display only some
parameters using -est table-, like so:

*-------------- begin example ---------------
sysuse auto, clear
qui reg price i.rep78 mpg foreign
est table, keep(mpg foreign) b se
*--------------- end example ----------------

Hope this helps,
