江苏省是我国油菜籽生产的主要省份，是农业部规划的优势“双低”油菜产品的重要生产区之一，油菜是江苏省仅次于水稻、小麦的第三大农作物，在农业生产中占有重要的地位。现阶段，江苏省油菜籽的生产过程中存在着种植规模小、生产分散、机械化程度低以及劳动力投入成本高等一系列问题，导致油菜籽生产的综合成本较高，同时也使得成本纯收益受到影响。 本文的研究主要是建立在相关农产品理论的基础上，通过对成本驱动因素与单位产量之间的偏相关分析，得出目前江苏省油菜籽生产过程中的成本驱动因素与产量之间的偏相关程度，在偏相关相关分析的基础上采用CD生产函数对江苏省油菜籽生产函数模型设计和检验，并采用双变量交互分析方法对江苏和河南等省的油菜籽生产成本进行比较优势分析，同时通过对江苏省主要油菜籽种植区成本与收益进行的分析，概述了目前各成本驱动因素在油菜籽生产成本中的比重与各个样本县市油菜籽经济效益现状，在此基础上找出目前江苏省油菜籽生产成本控制中存在的问题，从而提出江苏省油菜籽生产成本控制和经济效益提高的建议，提高江苏省油菜籽生产的竞争力。 本文通过分析发现，由于受到油菜籽销售市场价格、农业生产资料价格变化、自然灾害、病虫害以及生产方式和生产技术的进步影响，江苏省油菜籽生产单位面积各项成本与各项经济效益指标在年份之间均存在着极显著的差异，并且不同地区之间也存在着较大的差异。另一方面，通过分析还发现江苏省油菜籽种植的成本纯收益率虽然在全国居于前列，具有比较强的竞争优势，但是与临近的河南省相比仍然存在着一定的差距，这主要是由于在江苏省油菜籽的生产过程中存在着没有根据实际情况选取优良品种进行科学播种、肥料费的投入过多、机械化作业程度不高以及人工费用过高等问题。 因此，本文认为要提高江苏省油菜籽生产的成本与收益水平，首先需要政府加大对油菜籽种植生产的扶持力度，同时对各地的油菜籽生产结构进行宏观上调整，并且合理控制农业生产资料价格的过快上涨以及促进油菜籽市场供求平衡和稳定油菜籽的市场价格。另一方面，在生产过程中需要加快对良种的培育和推广，科学施肥，大力推行机械化，减低劳动力成本，以此在控制油菜籽生产成本的基础上提高油菜籽种植的经济效益的稳步增长。

Jiangsu is one of the main rapeseed production provinces, and it is one of the important production areas where the Ministry of Agriculture plans advantaged "double low" rape products. Rape after rice and wheat is the third largest crop in Jiangsu, and it plays an important role in the agricultural production. At present, a series of problems in the process of rapeseed production, such as planting at a small scale, decentralized production, low level of mechanization, high labor cost and so on, are not only lead to high comprehensive costs of rapeseed production, but also affect the net income of costs. The study shows that based on relevant theories of agricultural products, driving factors of costs and yields are analyzed by partial correlation analysis, and the result indicates the degree of partial correlation between driving factors of costs and yields in the process of Rapeseed production in Jiangsu. Based on partial correlation analysis, this paper adopts CD production function to design and test for rapeseed production function model of Jiangsu, and rapeseed production costs in Jiangsu and Henan are analyzed by the dual-variables interactive analysis. At the same time, analyzing the production costs and benefits of the main rapeseed planting areas in Jiangsu, the result shows the proportion of driving factors of costs in the process of rapeseed production and the current economic situation of rapeseed production in the sample counties and cities. According to this, the existing problems of cost control are found, and some suggestions about cost control of rapeseed production in Jiangsu and improving economic situation are put forward in order to improve the competitiveness of rapeseed production in Jiangsu. This paper shows that, one hand, due to being affected by rapeseed market prices, changes in the prices of agricultural production resouces, natural disasters, pests and diseases and ways of production and advances of production technology, there is a significant difference between all kinds of costs per unit area of rapeseed production in Jiangsu and all economic situation indices, and there is also a larger difference between different areas. On the other hand, the result through the analysis indicates that the net income rate of costs of rapeseed planting in Jiangsu is at the forefront of the country, and Jiangsu has strong competitive advantages, but there is still a gap comparing with Henan. The problems in the process of rapeseed production in Jiangsu are mainly summed up as selecting varieties to scientifically sow without actual situation, the high fertilizer costs, low level of mechanization, the high of labor costs and so on. Thus, in this paper, we conclude that in order to improve the level of Costs and benefits of rapeseed production in Jiangsu. First of all, the government supports rapeseed planting production, and takes measures for rapeseed production structure of many areas macroscopically. The government controls the sharp increase of price of agricultural production resources reasonably, and accelerates balance of supply and demand of the Rapeseed market and stability of the market price of Rapeseed. Also, in the production process, expedite the cultivation and generalization of well-bred seed, scientific fertilizer, vigorously promote the mechanization and reduce Labor costs, as on the basis of controlling production costs of Rapeseed, improving growth of the economic efficiency of Rapeseed cultivation
