| 摘 要： | 以Cobb-Douglas函数为基础，将对水稻产量起作用的种子、化肥、机（械）排（灌）电（力）和劳动力作为生产要素，建立数量经济模型.分析结果表明，机排电投入对水稻产量的影响最大，其次是化肥投入、种子投入和劳动力投入；上海郊区由于生产社会化程度普遍较高，扩大水稻的种植规模并不能明显增加水稻产量和农民纯收入，但可以提高劳动生产率，使得农民纯利润增加.

| 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. |
