本期为大家推荐的内容为论文“Urbanization, land conversion, and arable land in Chinese cities: The ripple effects of high-speed rail”（中国城市的城市化、土地转换和耕地变化:高速铁路的连锁反应），发表在“Applied Geography”期刊，欢迎大家学习与交流。

自2005年以来，中国交通部门在连接所有人口超过50万城市的目标驱使下，对高速铁路(HSR)基础设施方面进行了大量投资。本研究通过使用2005-2012年间发展高速铁路(HSR)基础设施的171个中国城市的面板数据，估计了高速铁路(HSR)网络扩张对农业用地转换的影响。结构方程模型(SEM)估计结果表明，高速铁路(HSR)对耕地征用有间接贡献，但对农用地转为城市用地有直接贡献。与此同时，房地产投资正在推动中国城市化进程中的农业用地减少。此外，高速铁路(HSR)网络扩展显示了一种地理模式，即西部地区对农业用地转换的影响明显强于东部城市，这表明高速铁路(HSR)驱动的土地转换更有可能发生在欠发达地区。

摘要ABSTRACT

Since 2005, Chinese transit authorities have made substantial investments in high-speed rail (HSR) infrastructure, driven by the ambition to connect all cities with over half a million people. This study estimates the impact of HSR network expansion on agricultural land conversion using a panel dataset for 171 Chinese cities that developed HSR infrastructure between 2005 and 2012. Structural equation modeling (SEM) estimation results show that HSR contributed indirectly to arable land requisition but directly to agricultural land converted for urban uses. At the same time, real-estate investments are driving agricultural land depletion in the process of China’s urbanization. In addition, HSR network expansion exhibits a geographical pattern where the effect on agricultural land conversion was considerably stronger in the western region than among eastern cities, suggesting that HSR-driven land conversion was more likely to occur in less developed places.
