上海郊区水稻生产的投入产出分析

Analysis of Input-output of Paddy Production in Shanghai Suburb

上海郊区水稻生产的投入与产出,在不同地区、不同品种、不同茬口类型和生产经营规模之间客观上存在着一定的差异性。南汇区单位面积产量最高,而嘉定由于成本投入较少单位利润和收入最高;播种面积最大的高产品种“嘉花一号”的价格较低,产值比“寒优湘晴”要低390元/hm2;甜瓜稻、菜稻等茬口水稻的成本和产量明显高于其他茬口;规模经营的优势主要体现在成本的降低与劳动生产率的提高上,而不在于单位面积产量的增加。

Some difference of Input-output of paddy production in Shanghai suburb exits objectively in different districts, varieties, stubble types and management scales, The highest paddy yield per hm^2 appeared in Nanhui, and the highest income and profit were brought in Jiading because of less cost. Jiajuayihao was higher yield of variety and had most extensive planting area, but its production value per hm^2 was 390 yuan less than Hanyouxiangqing variety because of lower price. Paddy＇ s cost and yield of melon-paddy or vegetable-paddy stubble was obviously higher than other stubbles. Advantage of scale management was mostly less cost and higher labor productivity, but not higher yield per hm^2.
