我国水产养殖苗种采纳影响因素研究OA

Field surveys of 157 shrimp farmers were conducted in Hebei,Jiangsu,and Shandong Province from 2023 to 2024,and a Logit Regression Model was applied to investigate the adoption of certified seed and its determinants.Results indicate that longer farming experience and the use of factory-based aquaculture systems significantly increase the likelihood of adopting nationally certified seed,while seed accompanied by virus inspection certificates is more strongly preferred.In contrast,cooperation with leading enterprises weakens farmers'autonomy,reducing adoption incentives.Membership in industry associations,however,promotes adoption through enhanced information dissemination and technical training.These findings suggest several policy implications as bellows.Government agencies should improve quality testing and certification systems and encourage the widespread issuance of virus inspection certificates.Industry associations should strengthen training and information services.Enterprises should explore differentiated chain-based promotion models,and farmers should enhance information acquisition and learning capacities.The practical promotion of nationally certified seed requires coordinated efforts across multiple stakeholders to achieve quality assurance and efficiency improvement.
