摘要
依据2002~2015年全国及宁夏粮食、蔬菜、苹果种植成本收益数据,运用收益比较指数、主成分回归、多元回归及边际收益分析等方法,对宁夏3种农产品生产的收益及其影响因素进行了比较研究。结果表明,宁夏水稻、小麦、玉米生产与国内比较,有优势、有劣势;粮食与蔬菜、苹果间的比较效益存在很大差距并且有扩大趋势;影响粮食与蔬菜、苹果比较效益差距拉大的主要因素包括价格变动、物质与服务费用以及人工成本的提高等。在研究结论的基础上,提出了具有针对性的政策建议。
Based on 2002~2015 national and Ningxia grain, vegetable and apple planting cost and return data, the benefits of three kinds of agricultural products in Ningxia and its influencing factors were studied by using the method of comparative index, principal component regression, multiple regression and marginal income analysis. The results showed that compared with the average level in China, the rice, wheat and corn production in Ningxia had advantages and disadvantages. There were big gaps between the grain and vegetables and apples in the comparative benefits, and there were an increasing trend in the gaps. The main factors that affected the gaps between the grain and vegetables and apples included price changes,material and service costs, and labor costs. Some aiming suggestions are put forward based on the research conclusion.
