摘　　要：推广生态农业技术对转变农业发展模式、促进农业现代化发展意义重大。以稻虾共作技术为例,利用长江中下游地区湖北、湖南、安徽共935份农户的微观调研数据,实证分析预期收益与技术补贴对农户采纳生态农业技术的影响。结果表明:(1)预期收益与技术补贴对农户生态农业技术采纳行为均有显著的正向影响;(2)预期收益与技术补贴对农户生态农业技术采纳行为的影响存在交互效应,在技术补贴相同的情况下,农户预期收益越高,越有助于生态农业技术采纳行为的发生;(3)从人力资本数量来看,预期收益与技术补贴对农户生态农业技术采纳行为的影响存在明显的异质性;(4)从代际差异来看,预期收益对农户生态农业技术采纳行为的影响存在明显的代际差异,老一代农户生态农业技术采纳行为普遍受到预期收益的影响,而技术补贴在农户生态农业技术采纳行为方面代际差异不明显。因此,政府既要加强顶层设计,针对稻虾共作技术制定系统的补贴方案,以更好地发挥其促进作用;也要强化农户对稻虾共作技术的收益预期,以提高农户采纳积极性,进而实现稻虾共作技术可持续发展。The promotion of agroecological technology is of great significance in transforming agricultural devel-opment mode and promoting the agricultural modernization.Taking rice-crayfish co-culture technology as an exam-ple,this study empirically analyses the impact of expected return and technology subsidy on farmers'adoption of agro-ecological by using microscopic survey data of 935 farmers in Hubei,Hunan and Anhui provinces in the middle and lower reaches of the Yangtze River.The results show that the expected return and technology subsidy both have a significant positive effect on Farmers'adoption of agroecological technology.Moreover,there is an interactive effect between expected return and technology subsidys on farmers'adoption of agroecological technology.Given the same technology subsidy,the higher expected return of farmers,the more it contributes to agroecological technology adoption behaviour.In terms of the quantity of human capital,there is significant heterogeneity in the effect of expected return and technology subsidy on farmers'adoption behavior of agroecological technology.In addition,there are significant intergenerational differences in the impact of expected return on farmers adoption of agroecological technology.Adoption behaviour of older generations of farmers is generally influenced by expected returns,while intergenerational differences do not show significant intergenerational differences in farmers'adoption behaviour of agroecological technologies.Therefore,the government should strengthen the top-level design and formulate a systematic subsidy scheme for rice-crayfish co-culture technology,so as to better play its promoting role.In the meantime,it is proposed to enhance farmers'expectations of the return of rice-crayfish co-culture technology,increasing their motivation to adopt it,and thus achieve sustainable development of the rice-crayfish co-culture technology.
