摘要
基于新疆昌吉州335份实地调研数据,从农户异质性特征、要素投入特征、技术信息来源三个方面选择9个指标比较棉农农业科技服务需求特征,进而探析棉农农业科技服务需求差异的影响因素。运用加权频数法、首项决定法和聚类分析法,比较棉农对农业科技服务的需求优先序;借助有序Logistic回归模型,研究棉农农业科技服务的需求意愿;采用二元Logistic回归模型,进一步探讨影响棉农采用农业科技服务的因素,再通过标准化系数公式度量农户分化对棉农农业科技服务采用程度的影响。估计结果显示,排在前三位的农业科技服务需求技术分别为新品种、病虫害防治和精量播种。农户分化、种植面积、家庭劳动力人数、农业科技服务满意度等显著影响棉农农业科技服务需求。农户分化视角下,男性(纯农户和兼业型农户)采用农业科技服务的概率更高;文化程度越高、家庭劳动力人数越多、种植面积越大的纯农户采用农业科技服务的概率越大;在40岁以上的样本中,年龄越大的兼业型农户采用农业科技服务的概率越高。
Based on 335 field survey data in Xinjiang, we compared the characteristics of cotton farmers’ agricultural science and technology services demand from three aspects: farmers’ heterogeneity characteristics,factor input characteristics, and technology information sources, and then explored the factors influencing the differences in cotton farmers’ agricultural science and technology service demand. Use weight frequency method, first decision method and cluster method to compare the priority of cotton farmers’ demand for agricultural science and technology services;with the help of ordered Logistic regression model, the willingness of cotton farmers’ demand for agricultural science and technology services was studied;a binary Logistic regression model was used, the factors affecting cotton farmers’ adoption of agricultural technology services were further explored, and then the standardized coefficient formula was used to measure the impact of farmers’ differentiation on the adoption of cotton farmers’ agricultural technology services;the estimation results showed that the top three agricultural science and technology service demand technologies were new varieties, pest control and precision seeding. The farmer differentiation, planting area, number of family dynamics and satisfaction with agricultural science and technology services significantly affected cotton farmers’ demand for agricultural science and technology services. From the perspective of farmers’ differentiation, male farmers and part-time farmers were more likely to adopt agricultural technology services;the higher the education level, the larger the labor force and the larger the scale of planting, pure farmers were more likely to adopt agricultural technology services;the higher the education level, the larger the labor force, and the larger the scale of planting, pure farmers were more likely to adopt agricultural technology services;the older part-time farmers were more likely to adopt agricultural technology services.
