研究目的:分析耕地利用显性转型和隐性转型各形态对湖南省农业经济增长的直接效应和溢出效应。研究方法:投影寻踪模型,空间自相关,空间计量模型。研究结果:(1)农业经济增长、耕地利用显性转型和隐性转型及各形态存在空间关联性;(2)耕地空间位置相邻性导致耕地利用转型各形态对农业经济增长不仅存在直接效应,还产生了影响相邻县域的溢出效应,即本县域农业经济增长1%,相邻县域农业经济将会增长0.28%;(3)耕地利用显性转型各形态对农业经济增长的直接效应和溢出效应高于隐性转型各形态,显性转型中耕地数量形态对农业经济增长的直接效应、溢出效应分别占到总效应的96.47%、34.97%。研究结论:应在合理...

The purpose of this paper is to explore direct and spillover effects of dominant and recessive transition of cultivated land use on agricultural economic growth in Hunan Province. The method of this paper is to measure transition level and analysis of spatial correlation by using Projection Pursuit Model, and to analysis the direct and spillover effects of transition on agricultural economic growth by using Spatial Econometric Model. The results show that: 1) agricultural economic growth, dominant and recessive transition of cultivated land use and their forms present significant spatial corre...
