I do not have much, but here we go:
Prouction of the Congress Poland in 1900 was worth 600 milions rubels, in 1910 860 milions. More than half of it was export to Russia, mostly textile goods (worth 226 milions in 1900, 349 milions in 1910), and metal products.
Most developed was textile industry - in 1900 about 44% workers were employed there. Polish textile goods dominated the market in Ukraine, Belarus and Lithuania (all parts of the Russian Empire).
The main industrial regions were: Łódź (mostly textile industry); Zagłębie Dąbrowskie (metal and chemical industry, foundries); Warsaw (metal industry)
In 1913 the domestic product per capita was worth about 63 today USD (comparing to 44 in Russia).
