摘　　要：种源是河蟹产业发展的关键,论文以上海河蟹主产区-崇明为例,对河蟹养殖户进行十年追踪调查,收集成蟹养殖生产和经营信息,共获得151份有效数据,分析河蟹养殖户采纳良种的意愿,并比较采纳良种与未采纳良种的上海主产区崇明河蟹养殖户在生产与经营水平上的差异,利用二元logit回归分析良种采纳率不高的主要原因。实证结果显示,成为体系示范点、获得生产补贴,更好的销售价格是影响良种采纳意愿的主要驱动力。对此,得出三方面的启示:一是吸引农户加入产业技术体系;二是提供生产补贴;三是提高河蟹品质,带动提高成蟹的售价。The crab seed is the key to the development of crab farming industry.A ten-year follow-up survey has been conducted on crab farmers in Chongming,the main crab farming area in Shanghai,and a total of 151 observations has been obtained to analyze the willingness of crab farmers to adopt the improved varieties.This paper intends to provide suggestions for promoting the application of improved aquatic varieties and explain the difference in productivity and profitability of crab farmers who adopted improved crab seed and those who did not adopt it.A logit regression has been used to identify the reasons behind the low adoption rate.The empirical results indicate that technical support,production subsidy and better market price are the significantly positive driving factors on the adoption.This study suggests that the application of new aquaculture technology could be promoted from attractingcrab farmers to join the project with technical support,providing production subsidy and enhancing the crab quality for better price.
