邻里效应与农技推广对农户稻虾共养技术采纳的影响分析——互补效应与替代效应

稻虾共养生态农业技术可以带来良好的经济、生态和社会效应,但由于有效技术来源不足、较高的技术与经济风险给农户采纳带来多重约束。以稻虾共养技术为例,利用湖北省与江苏省605份农户调研数据,通过理论与实证分析了邻里效应与农技推广对农户稻虾共养技术采纳的影响及二者的互补与替代效应。研究发现:(1)邻里观察性学习、交流感受均显著正向促进农户稻虾共养技术采纳。(2)通过农资企业的经营性农技推广显著正向影响农户稻虾共养技术采纳。(3)对农户稻虾共养技术采纳的影响上,观察性学习、社会规范均与农技推广存在部分替代效应,邻里农户交流感受与农技推广存在部分替代与互补效应。基于上述研究结论,该文认为应该有效结合邻里效应与农技推广的互补与替代效应,提高各农技推广主体的运行效率和实际影响力,进而提高农户的采纳规范性和效率。

Analysis on the Influence of Neighbourhood Effect and Agricultural Technology Diffusion on Farmer’s Adoption of Co-farming Technology of Rice and Crayfish：Complementary Effects and Substitution Effects

Co-farming technology of rice and crayfish could contribute to good economic, ecological and social effects. whereas farmers’ adoption confronted with multiple constraints because of inadequate sources of effective technology diffusion and high technical risk and economic risk. Based on a field survey dataset of farmers in Hubei Province and Jiangsu Province, this paper analyzes the influence of neighborhood effect and agricultural technology diffusion on farmers’ adoption of co-farming technology of rice and crayfish. After that, we analyzes the complementary and substitution effect of neighbourhood effect and agricultural technology diffusion on farmers’ adoption of co-farming technnology of rice and crayfish. The main findings are as follows: 1）Neighbourhood observation learning and communicating experience are both significantly positive to promote farmers’ adoption of co-farming technnology of rice and crayfish. 2)The diffusion of agricultural technology in agricultural enterprises has a significant positive impact on farmers’ adoption of co-farming technnology of rice and crayfish. 3)About the influence on the adoption of co-farming technnology of rice and crayfish in farmers, there are some substitution effects of Neighbourhood observational learning and agricultural technology diffusion, and so does the social norms; Some substitution and complementary effect of communicating experience and agricultural technology diffusion; Based on the above conclusions, this paper puts forward some policy suggestions to improve the operation efficiency and practical influence of each agricultural technology diffusion agent by combining the complementary and substitution effects of neighborhood effect, so as to improve the normality and efficiency of farmers’ adoption behaviors.
