摘要
文中在"贫困识别"的背景下,基于绥德县1314户农户调查数据,在可持续生计资本分析的框架下对比了不同类型农户的生计资本差异,借助DEA-BCC模型和Tobit回归模型,分析了生计资本对农业生产效率的影响。研究发现:(1)贫困户表现为自然资本和物质资本的缺乏,非贫困户表现为政策资本和金融资本的缺乏。(2)67.35%的农户缺乏人力资本,人力资本不足是制约黄土丘陵区农户生计水平提升的根本,金融资本和政策资本是导致贫困户与非贫困生计资本差异的关键。(3)黄土丘陵区的农业生产效率处于中等偏低的水平,近1/4农户的农业生产效率损失达70%以上。(4)改善自然资本、增加人力资本、缩小政策资本和金融资本在贫困户和非贫困户之间的差异,是提高黄土丘陵区农业生产效率、改善区域贫困状况的有效措施。
The characteristics of peasant household livelihood capitals are the key factors affecting agricultural production efficiency.Based on the survey data of 1314 households in Suide County,and focused on the background of precise poverty alleviation strategy,we analyzed the difference of farmers′livelihood capitals and their impacts on agricultural production efficiency.The results show that:(1)Poor households are mainly manifested in the lack of natural capital and material capital,while non poor households are manifested in the lack of policy capital and financial capital.(2)There are 67.35%of farmers who are lack of human capital,which restricts the development of farmers′livelihood level in loess hilly area.Financial capital and policy capital are the key factors that caused the difference of livelihood capital between poor and non-poor households.(3)The agricultural production efficiency in the Loess Plateau area is at a moderately low level,25%of households lost more than 70%of their agricultural efficiency.(4)Improving the natural capital,increasing human capital,reducing the differences between policy capital and financial capital between poor and non-poor households are the key measures to improve the agricultural production efficiency of loess hilly area.
