摘要:

耕地利用集约度对粮食安全、生态环境和耕地保护有深刻影响。利用重庆市酉阳县、武隆县、巫山县3个县12个典型村972份有效农户调查样本,基于货币额衡量生产成本,对比分析不同类型农户的耕地利用集约度差异,同时综合价值形态指标与实物形态指标对其内部结构进行分析比较,然后运用多元线性回归模型定量分析不同类型农户内部耕地利用集约度的影响因素,以期为政府制定山区农业发展政策与措施提供科学依据。研究表明:① 不同类型农户的耕地利用集约度及其内部结构存在较大差异,劳动集约度、资本集约度与耕地利用集约度基本呈现自然资产型>人力资产型>基本型>缺失型的关系;② 研究区正经历着农村劳动力快速转移过程,农户生计多样化显著,但生计多样化并不一定意味着耕地集约度的降低;③ 农业生产补贴和经济作物播种面积比重对自然资产型农户有显著的正向影响,故农业发展政策应集中在提高农业生产补贴和调整农业产业结构方面,前提是继续采取有效措施改善农村交通水利等基础设施,建立农业发展的平台。

Abstract:

The change of cultivated land use intensity has influenced food security, ecological environment and cultivated land protection. Using 972 valid samples through household survey of 12 typical villages in Youyang county, Wulong county, Wushan county of Chongqing as study cases, we comparatively analyze cultivated land use intensity of households of different livelihood strategies based on the cost of production. And we also compare its internal structure considering comprehensive form of value index and physical form indicators. Then, we analyze the influencing factors of cultivated land use intensity of households of different livelihood strategies by adopting multivariate linear regression model. Finally, the purpose of the study is to provide scientific basis for the governments at all levels to formulate policies for agricultural development. The results are shown in the following aspects. (1) There are great differences in cultivated land use intensity and its internal structure of households of different livelihood strategies, as well as labor intensive degree, capital intensive degree and land use intensity. Ⅲ-1 (natural assets type household)>Ⅲ-2 (human assets type household)>Ⅱ (basic type household)>Ⅰ (missing type household). (2) The study area is experiencing rapid rural labor transfer process and livelihood diversification of farmers is significant. But the livelihood diversification does not necessarily mean the reduction of cultivated land use intensity. (3) Agricultural production subsidies and the proportion of cash crops planting area have significant positive effects on Ⅲ-1. Hence, government policies for agricultural development in the future should focus on the improvement of agricultural production subsidies and the adjustment of the agricultural structure, but the premise is to continue to take effective measures to improve rural infrastructure and create a good platform for agricultural development.
