社会互动和信息获取能力对农户稻虾共作技术采纳行为的影响

doi:10.19741/j.issn.1673-4831.2021.0142

摘要/Abstract

摘要： 稻虾共作技术作为典型的生态农业技术，是缓解生态环境恶化、保障农业可持续发展的重要途径。利用长江流域878份调研数据，采用项目反应理论（IRT）模型测度信息获取能力，并在此基础上借助Heckman模型分析社会互动、信息获取能力对农户稻虾共作技术采纳行为的影响，进一步讨论信息获取能力的中介效应。结果表明：（1）利用渠道越多的农户，其信息获取能力也越强；在相同数量的渠道组合中，区分度越高的渠道可以获得更高的信息获取能力。（2）在社会互动中，社会交往、人情互惠和社会规范均可促进农户稻虾共作技术采纳决策；同时人情互惠还对采纳程度产生正向影响。（3）信息获取能力对农户稻虾共作技术采纳决策和采纳程度均有促进作用，同时社会互动可以通过信息获取能力来促进农户的采纳决策；而社会互动中的人情互惠则通过信息获取能力对农户采纳程度产生影响。因此，需要构建多层次技术信息渠道，拓宽农户的信息网络，并组建农村交流平台，开展丰富的农村文化活动，增进农户的交往并形成情感交流，促使"付出-回报"的良性循环系统正常运转。

Abstract: As a typical ecological agriculture technology, the rice-shrimp co-cultivation technology is an important way to alleviate the deterioration of the ecological environment and ensure the sustainable development of agriculture. The item response theory (IRT) model was further used to measure the information acquisition capacity. On this basis, the Heckman model was further used to analyze the impact of social interaction and information acquisition capacity on farmers' adoption of the rice-shrimp co-cultivation technology by using 878 survey data in the Yangtze River Basin. And the mediating effect of the ability to obtain information was further discussed. The results show that:(1) The more channels that farmers used, the stronger their ability to obtain information. In the same number of channel combinations, the channels with higher discrimination could lead to higher information acquisition capabilities.(2) Social interaction, reciprocity and social norms could all encourage farmers to adopt rice and shrimp co-cultivation technology. Reciprocity also had a positive impact on the degree of adoption. (3) Information acquisition capacity had a positive effect on the decision-making and the degree of adoption of farmers' rice-shrimp co-cultivation technology. Social interaction can promote the adoption and decision-making of farmers through the ability to obtain information. While the reciprocity can be achieved through the ability to obtain information which could have an impact on the degree of adoption of the technology by the farmers. Therefore, it is necessary to build a multi-level technical information channel system, broaden the information network of farmers, establish a rural exchange platform to carry out rich rural cultural activities, and enhance the interaction of farmers and form emotional exchanges, and promote the normal operation of the "pay-reward" virtuous cycle system.

Key words: social interaction, information acquisition capacity, the rice-shrimp co-cultivation technology, adoption behavior, mediating effect
