空间异质性视角下的农地租赁价格影响因素研究

A Study of Influencing Factors on Rural Land Lease Prices from the Perspective of Spatial Heterogeneity

地租的快速上涨是国内农产品生产成本居高不下的重要原因之一,尤其在经济发达的粮食主销区,经济发展对地价产生巨大的抬升作用,从而影响地租的生成。采用广东省120个县的土地租赁价格数据,从空间异质性视角,分析农地供应、劳动力密度及经济发展对农地租赁价格的影响,利用广东省120个县的土地租赁价格数据,构建OLS与GWR模型进行实证分析。实证结果表明:农地租赁价格存在明显的空间相关性且在经济发达,人口稠密的地区表现更为显著,农地供给、农地需求及经济发展三者在不同地区对地租的影响强度不一。由于存在空间异质性,地方政府应完善产销区利益补偿机制,探索农业支持补贴自筹自给的办法,并进一步发挥市场在产业升级中的作用。

The rapid increase in the cost of land rents is one of the important reasons why domestic agricultural production costs remain high,especially in the economically developed regions where grain is mainly sold,economic development has a huge uplifting effect on land prices,which will affect the generation of land rents.Based on the perspective of spatial heterogeneity,the paper explores the impact of farmland supply,labor density and economic development on land rental prices,using a set of land rental price data collected from 120 counties of Guangdong Province,and constructs an empirical analysis of OLS and GWR model.The results indicate:The spatial correlation and spatial heterogeneity in land rental prices do obviously exist,and the impact of farmland supply,farmland demand and economic development on rents varies from region to region.According to the spatial analysis results of heterogeneity,local governments should improve the compensation mechanism for production and marketing areas and explore ways to support self-sufficiency in agricultural support subsidies,and pay more attention to the role of market in industrial upgrading.
