BEIJING, Nov 11 (Reuters) - China's production of metals, fuel and power stayed at record levels last month as industrial output hit a 19-month high, but falling imports of copper and iron ore fuelled doubts whether it really needed so much material.

As so often in the past year, calendar-related blips in the data and the inexact influence of China's huge stockpiles have obscured the true picture of demand for each commodity, making it hard to judge if China's growth is solid or hollow.
