Since the beginning of 21st century, as China's industrialization and urbanization goes quickly, steel production climbs up largely based on a strong demand of iron ores. In particular, from 2004 to 2009, a rapid growth of imported iron ores resulted in a continuous rise in price. According to the shortterm model of mineral resources constraints on economic growth, constraints of iron ore resources to China's economic growth is measured via 2001—2009 iron ore export & import data and GDP data, demonstrating a continuedrising influence to the absolute value of economic growth, from 0.42% in 2004 to 2.92% in 2009. Iron ore resource is a big constraint to China's economic growth especially to industrial growth in a short term, but still remains a strong influence for a long time in the future.
