【摘要】 研究目的:揭示土地市场化对于农地非农化的影响并对其作用区间进行分析。研究方法:采用综合指标评价和门槛效应模型,在确定土地市场化水平基础上,分不同区域和出让区间考察土地市场化对于农地非农化的影响机制。研究结果:(1)土地市场化水平对于农地非农化的影响是分区间性的,到达一定门槛值后,会产生较为显著的负向影响;(2)不同城镇化水平地区在出让价格提高过程中,都经历土地市场化对于农地非农化的正向作用区间;(3)"高价位陷阱"反映了较高出让价格区间下,土地市场化对于农地非农化产生促进,而导致过度非农化的情况。研究结论:通过市场化的作用减少农地过度非农化,需把握土地出让价格的上涨和作用区间,合理有效利用市场调节机制。更多还原

【Abstract】 The purpose of this paper is to reveal the land market’s impact on farmland conversion and to analyze its impact interval. Methods including index evaluation and threshold effect model are applied to investigate the responding mechanism of farmland conversion to land marketization in different regions and the price interval based on the land marketization levels. The results show that: 1)the influence of land marketization on farmland conversion changes according to the different price interval, showing a significant negative impact after reaching certain threshold value. 2)Land market plays more effectively under higher transfer price level, which is proved by three different areas’ results. 3)The "high-price level trap" situation means land marketization plays promoting role on farmland conversion among high price interval, which may lead to excessive farmland conversion. The conclusion is that reducing the excessive farmland conversion through land marketization needs to recognize the rising of land prices and its function range, and then make reasonable and effective use of market regulation mechanism.更多还原
