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.
