山东省城镇化对耕地压力的影响分析

Analysis on the Impact of Urbanization on Cultivated Land Pressure in Shandong Province

随着中国城镇化进入快速发展阶段,城镇化究竟如何影响耕地压力的研究具有重要的现实意义,了解两者之间的作用机制,有利于更好地处理两者的关系。为此,构建耕地压力指数指标,使用双向固定效应、两阶段最小二乘法等方法研究人口城镇化与土地城镇化对耕地压力的影响,并根据耕地压力指数大小分地区进行考察。研究表明,人口城镇化与土地城镇化分别对耕地压力具有负向和正向作用,城镇化整体对耕地压力的影响主要取决于后续对闲置土地的整合利用程度。最后根据研究结果提出针对性建议。

Since China’s urbanization’s entering a stage of rapid development,the problem of cultivated land is becoming increasingly prominent.The research on how urbanization affects the pressure of cultivated land also has important practical significance.Only by understanding the mechanism between them can we better deal with the relationship between them.Firstly,the cultivated land pressure index was constructed,and the effects of population urbanization and land urbanization on cultivated land pressure were studied by using the methods of two-way fixed effect and two-stage least square method,and investigated by regions according to the size of cultivated land pressure index.The research shows that population urbanization and land urbanization have negative and positive effects on cultivated land pressure respectively.The overall impact of urbanization on cultivated land pressure mainly depends on the subsequent integrated utilization of idle land.Finally,according to the research results,targeted suggestions are put forward.
