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。
Based on the sample survey data of 133 households in 4 administrative villages of 2 county-level cities in coastal saline-alkali area of Jiangsu Province, this study established logistic regression model based on Logistic regression model of Willingness to Choose Alkali Improvement Technique and their respective variables, and from the characteristics of farmers, family characteristics, policy orientation , Social environment, analysis of four factors that affect farmer’s choice of technology to improve saline-alkali land. The results show that there is a high prevalence rate of chemical bio-technology improvement in Dafeng and Dongtai 2 cities. The farmers with large family agriculture population and big net agricultural income are more willing to improve the technology of saline-alkali land. The non-agricultural employment affects farmer households Saline-alkali land; agricultural policies such as subsidies, agricultural insurance and loan factors have a limited impact on the choice of improved technologies; Dongtai and Dafeng 2 cities generally agree on their willingness to improve their technologies for salinization. Some factors are influential in the direction and Significantly different slightly.
