摘要 基于浙江省4个县(市)的山区农户调查数据,通过运用CD生产函数方法对化肥经济投入是否过量进行分析。研究发现:被调查的浙江省4个县(市)化肥施用量均超过了经济意义上的最优施肥量,农户对粮食作物、经济作物种植中的化肥投入均过量,其中粮食作物化肥过量施用程度较严重。运用计量经济模型对化肥经济过量施用量的影响因素进行分析,结果表明农户参与非农就业的比例以及地块的质量、灌溉条件等因素是导致化肥经济过量施用行为的重要影响因素。 The impact of excessive use of chemical fertilizers on the environment is intensifying steadily nowadays. Based on the survey of farm households in four counties( cities) in the mountainous region of Zhejiang Province,CD production function method was used to analyze economically whether the application of chemical fertilizers in the region exceeds the actual need or not. It was found that the chemical fertilizer application rate prevailing in the four counties exceeded the optimal rate in the economic sense. The farmers over-fertilized food crops and cash crops, particularly food crops.Meanwhile,the econometric model was used to analyze factors stimulating over-consumption of chemical fertilizers. Results show that the proportion of the farmer population participating in non-agricultural employment,quality of the land and irrigation conditions are the major factors stimulating excessive application of chemical fertilizers. Based on the findings,some suggestions are put forth for policy-making.
