有害生物综合防治对农户生产经营收益的影响——基于山东省三个县级市的问卷调查

Impact of Integrated Pest Management upon Farmers' Income: A Questionnaire Survey in Three Cities of Shandong Province

有害生物综合防治(IPM)对改善环境质量具有积极作用,已被公众广泛接受,但是其对农户生产经营收益的作用效果尚无实证研究。本文对山东省莱阳、莱州和安丘三市的农户进行有害生物综合防治(IPM)相关问题的问卷调查,利用所得数据进行描述性分析及投入产出比例和柯布-道格拉斯生产函数计量分析,旨在论证农户是否能从采用这一环境友好型生产方式中受益。结果显示,整体来看农户安全生产意识较差,对IPM的了解程度不足;IPM生产方式比传统种植方式更节约劳动力、化肥、灌溉和农药费用;IPM生产方式会对农户的经营效率产生显著的正向影响。

It has been widely accepted by the public that integrated pest management （IPM） can play a positive role in improving the environmental quality; however, no empirical research on the effect of IPM to farmers＇ operating income has been carried out. In this paper, a questionnaire survey related to the integrated pest management（IPM） was conducted among the farmers in Laiyang, Laizhou and Anqiu cities of Shandong Province. The data was analyzed by descriptive analysis, input-output ratio and Cobb-Douglas production function econometric analysis, aimed at clarifying whether the farmers would benefit from the environmentally friendly production method. The results showed that the farmers＇ consciousness of production safety was poor, overall, and also lacked of understanding of IPM; IPM production method was more economical than that of the traditional planting pattern, because of a less cost for labor, fertilizer, irrigation and pesticides; the IPM production method had a significantly positive impact on the farmers＇ operating efficiency.
