【摘要】：合理有效的效率评价手段是准确认识耕地资源利用效率的关键,而分析效率的影响因素为耕地资源利用效率的提升提供了方向。本文引入四阶段DEA法对2012年湖北省耕地资源利用效率进行精确评价,并运用Tobit回归模型分析效率的影响因素。研究表明:湖北省耕地资源利用效率整体水平不高,且主要由纯技术效率偏低所致;在耕地利用过程中,武汉、宜昌两市在技术和规模上均有效,襄阳市和神龙架林区仅在技术上有效,其余13个地区不存在技术有效和规模有效;武汉和宜昌2市的耕地经营规模处于适度水平,仅襄阳市耕地经营规模过大,其余14个地区的耕地经营规模尚具一定潜力;改善农田水利条件会加剧耕地资源投入以及从事耕地生产的劳动力资源投入的相对过剩程度,而提高农民收入水平会削减耕地资源以及从事耕地生产的劳动力资源的过度供给;提高地区经济发展水平有利于提高耕地资源利用效率,而耕地机械化投入水平的提高不利于耕地资源利用效率的提高。
[Abstract]:Reasonable and effective efficiency evaluation method is the key to understand the utilization efficiency of cultivated land resources accurately. In 2012, this paper introduces the four-stage DEA method to evaluate the utilization efficiency of cultivated land resources in Hubei province. Tobit regression model was used to analyze the influencing factors of efficiency. The results showed that the overall level of utilization efficiency of cultivated land resources in Hubei Province was not high and was mainly caused by the low efficiency of pure technology. In the process of cultivated land utilization, Wuhan and Yichang are both effective in technology and scale, Xiangyang city and Shenlongjia forest area are only technically effective, and there are no technical efficiency and scale efficiency in the other 13 areas. The scale of cultivated land management in Wuhan and Yichang is at a moderate level, only Xiangyang is too large, the other 14 regions still have some potential. Improving irrigation and water conservancy conditions will aggravate the relative surplus of input of cultivated land resources and labor resources engaged in cultivated land production. Raising farmers' income level will reduce the excessive supply of cultivated land resources and labor resources engaged in cultivated land production. Raising the level of regional economic development is conducive to improving the utilization efficiency of cultivated land resources, while the increase of input level of cultivated land mechanization is not conducive to the improvement of utilization efficiency of cultivated land resources.
