摘要
研究目的:针对快速城镇化地区农户生计分化现象,以上海市青浦区为例,对不同生计策略类型农户的耕地利用集约度进行评价,并分析其影响因素,以期为改善农户土地利用行为、实现土地资源合理高效利用与农户生计可持续发展提供政策参考。研究方法:运用价值形态测度方法核算各生计类型农户的耕地利用集约度,以两水平方差成分模型确定耕地利用集约度影响因素。研究结果:(1)不同生计策略类型农户耕地利用集约度存在差异性,大小顺序依次为专业农业型、传统农业型、农业兼业型、非农兼业型,劳动集约度与资本集约度排序与之基本一致;(2)同一生计策略类型农户的耕地利用集约度存在相似性,耕地利用集约度的总变异中有24.32%是由农户生计策略类型不同而引起的,水平一中农业收入比重、农业补贴、耕地面积、地块平均离家距离、农户离集镇距离与水平二中是否兼业等是影响农户耕地利用集约度的显著因素;(3)模型拟合效果评价表明该方法具有可行性。研究结论:耕地利用集约度不仅与农户自身禀赋有关,而且受生计类型影响,政府相关部门应结合当地实际情况引导农户对这两方面进行调整或完善。
The purpose of this study is to provide the policy reference for improving rural households' land use behaviors as well as for realizing rational and efficient land resource use and sustainable rural household livelihoods through evaluating the cultivated land use intensity of different types of rural household livelihood strategies and analyzing the impact factors. The methods of the paper used are as follows. It aimed at the phenomenon of farmers' livelihood differentiation in the rapid urbanization areas and took Qingpu District of Shanghai as an example. The cultivated land use intensity of farmers was calculated by measurement method of value form. The two level variance component model was used to determine factors affecting the cultivated land use intensity. The results show that: 1) there are differences in cultivated land use intensity of different types of rural household livelihood strategies, and the order of their size is as follows: specialized agriculture households, conventional agriculture households, agriculture-dependent households, offfarm-dependent households. The orders of labor intensive degrees and capital intensive degrees are in consistent with the order of land use intensity. 2) There exists the similarity regarding the cultivated land use intensity among the same type of rural household livelihood strategy and 24.32% of the total variation of cultivated land use intensity is caused by rural households' livelihood strategies differentiation. The proportion of agricultural income, agricultural subsidies, cultivated land area, average distance from the fields, distance from the central town(Level 1) as well as whether rural households have part-time jobs(Level 2) are the significant factors affecting the cultivated land use intensity of rural households. 3) The fitting effect evaluation of the two level variance component model indicates that this method is feasible. In conclusion, cultivated land use intensity is not only related to rural households' own endowme
