新疆甜菜生产的比较效益分析

依据新疆甜菜、棉花、玉米、小麦的成本收益数据,从成本增长和结构变化、成本差异、土地产出率、纯收益和成本收益率及其农产品价格变动等方面进行比较分析.结果表明,甜菜与玉米、小麦等粮食作物相比,具有一定的竞争优势;与棉花等效益较高的经济作物相比,具有竞争劣势.甜菜生产的比较优势在适宜产区形成了竞争优势,得到了较好发展;由于棉花等高收益作物在新疆的发展,对甜菜生产形成了较大的竞争压力,抑制了甜菜产业在新疆的发展规模和速度.

Analysis on Comparative Benefit for Sugar Beet Production in Xinjiang

Comparative superiority for sugar beet production were analyzed based on cost and benefit data of sugar beet, cotton, maize and wheat from cost growth and structure change, the difference of cost, land output, pure yields benefits and costs, and the agricultural products price change, etc.. The result showed that sugar beet had a certain competitive advantage compared with food crops such as corn, wheat; op- posite had a competitive disadvantage compared with the high economic crops such as cotton. The comparative superiorty of sugar beet produc- tion in appropriate regions had formed a competitive advantage, and developed better. Due to the development of high-yielding crops such as cotton sugar beet production faced a huge competitive pressure, which was suppressed in development scale and speed in Xinjiang.
