文章对农作物区域产量保险费率厘定方法的参数法和非参数法的研究文献进行了综述,并对两种方法的利弊进行了简要的分析说明,指出农作物的产量受到各种因素的影响,如农民投入的可变生产要素,气象条件等。简单的通过以时间为自变量对历史数据拟合得到趋势产量的做法可能并不可取。 This paper summarizes the research methods of parametric and non-parametric methods for determining crop yield insurance rates, and briefly analyzes the advantages and disadvantages of the two methods. It points out that crop yields are affected by various factors, such as Farmers input variable production factors, weather conditions. It may not be advisable simply to get the trend yields by fitting the historical data to the time-dependent.
