利用安徽省水稻种植农户调查数据,基于OLS估计结果表明:同传统病虫害防治方式相比,采用化学型IPM技术、生物型IPM技术可以分别使亩均粮食增收约8.42千克、14.90千克。影响粮食产量的因素还包括:户主性别、文化水平、种植规模和种子费用。对病虫害产量损失顾虑、资本和劳动力资源限制,以及不能掌握某些复杂的IPM技术操作是制约农户采纳IPM技术的主要原因。有必要通过政府政策创新和经济激励机制,诱导农户IPM技术采纳行为,在实现产量增长的经济效益的同时,实现环境保护的社会效益目标。
Based on the survey data of paddy rice farmers in Anhui Province, based on the OLS estimation results, it is shown that the chemical IPM technology and biological IPM technology can increase the average grain yield per mu by 8.42 kg and 14.90 kg, respectively, compared with the traditional pest control methods. Factors affecting food production also include: head of the gender, cultural level, planting size and cost of seeds. Concerns over loss of pests and diseases, restrictions on capital and labor resources, and the inability to master some of the complex IPM technology operations are the main constraints to farmers’ adoption of IPM technology. It is necessary to induce farmers to adopt IPM technology through government policy innovation and economic incentive mechanism and achieve the social benefits of environmental protection while realizing the economic benefits of increased output.
