基于2015年辽宁省“百村千户”调研数据，采用Probit模型分析加入合作社对农户农业新技术采纳行为的影响。研究发现：相对于非社员农户，社员农户采纳农业新技术的倾向更高，加入合作社显著提高了农户农业新技术采纳水平，且对种植大户和多元化种植户的促进作用更大。加入合作社对农户在种子、化肥、农药、农业机械设施、耕作方式、田间管理、储藏加工、灌溉方式、无公害生产等农业新技术采纳上都存在显著的促进作用，其中，对无公害生产技术采纳行为的影响最大，对农药新技术采纳行为的影响最小。进一步研究发现，加入合作社有助于提高技术可及性和议价能力，进而促进农户采纳农业新技术。

Based on the data of “100 Villages, 1000 Households” of Liaoning province in 2015, the effect of joining cooperative on the adoption of new agricultural technology has been analyzed through using Probit model. The study shows that compared with non-member farmers of cooperative, member farmers are more likely to adopt new agricultural technology. Joining cooperative could significantly promote the adoption of new agricultural technology, especially for the farmers of large-scale planting and diversified planting. Farmers who join the cooperative have a higher tendency to use new agricultural technologies of seeds, fertilizer, pesticide, agricultural machinery facilities, farming methods, field management, storage and processing, irrigation, and pollution-free production. Joining cooperative has the greatest impact on pollution-free production technology and the smallest influence on pesticide technology. Further research finds that joining cooperative helps to improve technology accessibility and bargaining power, and thereby promote farmers’ adoption of new agricultural technologies.
