Peasant households＇ inclination to select improving technology for saline-alkali land and its influencing factors. A research based on 133 peasant households in the saline costal region of Jiangsu Province | 区域盐碱地改良技术的农户选择意愿及影响因素――基于江苏省滨海盐碱区133户农户的调查

chinois. 利用江苏省滨海盐碱区2个县级市4个行政村133户农户的抽样调查数据，通过建立农户盐碱地改良技术选择意愿与各自变量的Logistic回归计量模型，从农户特征、家庭特征、政策导向、社会环境4个方面分析农户选择盐碱地改良技术行为的影响因素。研究结果表明：大丰、东台2市以秸秆还田为代表的化学生物改良技术普及率较高；家庭农业人口多，农业纯收入大的农户更加意愿进行盐碱地技术改良；非农就业情况影响农户盐碱地改良的行为决策；农业政策诸如补贴、农业保险、贷款因素等对改良技术选择的影响有限；东台、大丰2市影响农户盐碱改良技术的意愿的因素大体一致，部分因子在影响方向和显著程度上稍有不同。

anglais. Based on the sample survey data of 133 peasant households of four administrative villages in two county- level cities in the saline costal region of Jiangsu Province, authors anatyzed the influencing factors of peasant households＇ behavior in selecting improving technology from four aspects, household characteristics, family characteristics, policy guidance and social environment. By a self-developed estimation model, the logistic regression metric model ,specifying relationship between peasant households＇ inclination and independent variables. The research indicated that biochemistry improving technology represented by straw returning was relatively popular in Dafeng and Dongtai. Peasant households with larger agricultural population and more agricultural income were more willing toimproving technology for treating saline-alkali land. Moreover, non-agricultural employment also had some impacts on peasant households behavioral decision. Agricultural policies like subsidies,agricultural insurance and loan had limited influences on selection of improving technology. Additionally, the factors influencing Dongtai and Dafeng＇s peasant households＇ inclination to improving technology for treating saline-alkali land were similar, except for several factors slightly different in influencing directions and impact significance.
