| 摘要: |
| 海水养殖是海洋经济重要的组成部分。中国是世界上最大的对虾养殖国，对虾养殖净收益直接影响对虾养殖户的生产积极性，进而影响对虾养殖产业持续稳定健康发展。文章以山东省、江苏省和广东省对虾养殖户的调查数据为依据，运用多元线性回归模型，对对虾养殖净收益的影响因素进行实证分析。结果表明，影响对虾养殖净收益的3个主要因素是：①每年对虾养殖的造数;②是否参加对虾养殖农业合作社;③对虾出塘的销售价格。对虾养殖者的年龄，受教育程度，是否混养其他品种生物，养殖模式，养殖面积对对虾养殖净收益影响不显著。基于回归结果，笔者提出完善对虾养殖基础设施；发展对虾养殖农业合作社和养殖协会；建立稳定的对虾市场价格调控体系等政策建议。 |

| Abstract: |
| Aquaculture is an important part of marine economy.China is the largest shrimp farming country in the world,and the net income from shrimp farming directly affects the production enthusiasm of shrimp farmers,which in turn affects the sustainable and healthy development of the shrimp aquaculture industry.Based on the survey data of shrimp farmers in Shandong province,Jiangsu province and Guangdong province,this paper used multiple linear regression models to empirically analyze the influencing factors of shrimp net aquaculture income.The results showed that: The three main factors affecting the net income of shrimp aquaculture are (1) the annual number of shrimp aquaculture; (2) whether it participates in the shrimp farming agriculturalcommunity; and (3) the selling price of the shrimp out of the pond.The age of shrimp farmers,the degree of education,whether they breed other breeds of organisms,the mode of aquaculture,and the area of culture have no significant effect on the net income of shrimp aquaculture.Based on the regression results,the paper proposed to improve the shrimp aquaculture infrastructure,the development of shrimp farming agricultural cooperatives and aquaculture associations,and established a stable market price control system for shrimp,and other policy recommendations. |
