土地复垦对农业产出的影响研究
摘 要
土地复垦是缓解我国人地矛 *51今日免费论文网|www.51jrft.com +Q: ^351916072
盾,为我国经济发展提供用地保障的重要手段。鉴于此,本文运用全国31个省级行政区(除香港、澳门、台湾外)的统计数据,通过固定效应的空间滞后模型研究土地复垦对农业产出的影响机制,并检验土地复垦与农业产出之间在空间上是否存在溢出效应。据此研究发现:(1)从全国层面看,复垦新增耕地面积对农业产出具有抑制作用,即土地复垦抑制农业产出的增加;(2)从区域层面看,不同经济发展水平地区,土地复垦对农业产出的影响有差异,经济较发达地区土地复垦对农业产出的抑制作用较显著;(3)从农业投入层面看,不同的农业投入对农业产出的影响不同。第一产业从业人员数抑制了农业产出,而化肥施用量却能促进农业产出,农业机械总动力则是对其作用影响不大。根据研究结果,得出研究结论:要实现土地复垦对农业产出的促进作用,应促进复垦土地集约化、规模化,同时统筹城乡劳动力市场,合理安排农村劳动力,并实现农业的“三产融合”,构建现代化农业体系。
RESEARCH ON THE IMPACT OF LAND RECLAMATION ON AGRICULTURAL OUTPUT
ABSTRACT
Land reclamation is an important means to ease the contradiction between people and land in China and provide land security for Chinas economic development. In view of this, this paper uses the statistical data of 31 provincial administrative regions (except Hong Kong, Macau, and Taiwan) to study the impact mechanism of land reclamation on agricultural output through a fixedeffect spatial lag model, and examines whether there is a spatial spillover effects between land reclamation and agriculture outputs. According to this study, it is found that: (1) From the national level, the newly cultivated land reclamation has an inhibitory effect on agricultural output, that is, land reclamation inhibits the increase of agricultural output; (2) From the regional level, land reclamation in areas with different economic development levels, there are differences in the impact on agricultural output, and land reclamation in more economically developed regions has a significant inhibitory effect on agricultural output; (3) From the perspective of agricultural input, different agricultural inputs have different effects on agricultural output. The number of employees in the primary industry suppresses agricultural output, while the amount of fertilizer application can promote agricultural output, and the total power of agricultural machinery has little effect on its effect. Based on the research results, we draw the following conclusions: To realize the promotion of land reclamation on agricultural output, we should promote the intensification and scale of reclaimed land, and at the same time coordinate the urban and rural labor market, rationally arrange rural labor, and realize the "three "Industry integration" to build a modern agricultural system.
