Abstract: Since the half year of 2002, the tide of heavy and chemical industry in China is rising. Today this tide doesn’t retreat. Needing or not and how to develop heavy and chemical industry caused a broad argument in academic circles. Based on the real national and international condition, we think that it can not continue to develop heavy and chemical industry according to the west traditional pattern. If China follow the old western way, it will fall in "the Hoffman trap ". China developing its own heavy and chemical industry must walk on the "light" road. For doing this, it should increase the "soft" and "light" element in the input, process and output of production, and ultimately this will makes it accomplish its industrialization course smoothly.
