Abstract: Based on the Cobb-Douglas function, an econometric model for paddy′s production in the suburb of Shanghai was established. In the model, seeds, fertilizer, machine, irrigation and drainage, electric power (MIE), and labor were regarded as the production elements effecting paddy′s yield. The conclusion is that the most effective factor on paddy′s yield is MIE′s input, and the inputs of nutrition, seeds, and labors are followed in order. With the increase of planted scale of paddy, farmer′s benefit can be added up, but the increase of paddy′s yield and farmer′s income is not obvious.

Key words: paddy, yield, Cobb-Douglas function, Shanghai suburbs, paddy, yield, Cobb-Douglas function
