The difference of the cotton production cost between the provinces in china was significant. in compare to the other countries of the planting cotton, the production cost per 666. 7m2 was high, and the cost per 50 kg lint was low, however, the composition of the cost was not reasonable. there were multiple linear regression relationships between production cost per 50 kg lint cotton and labor cost per day, planting area per family and the lint yield per 666. 7 m2
分析認為，生產成本是我國棉花成本的構成主體，人工、化肥和農藥又是生產成本的主體；我國不同產棉省區具有明顯的成本優勢差異；與國外相比，我國畝成本缺乏優勢， 50公斤皮棉成本優勢明顯，但成本結構不合理；我國50公斤皮棉成本差與要素價格差、生產規模和技術水平差具有線性關系；市場配置棉花生產資源比國家政策更高效。
