Abstract
Low agricultural land use efficiency (ALE) is an important issue that restricts agricultural economy. This study explores the impact of high-speed rail (HSR) on ALE in China’s counties. Calculate ALE based on a two-stage dynamic network model with shared inputs, and analyze the impact of HSR on ALE in the production stage and benefit transformation stage. Results show that: (1) HSR can promote ALE, and has a higher promoting effect on ALE in the benefit conversion stage. (2) Characteristics of HSR (including HSR speed, commuting frequency, and irreplaceability) as well as the characteristics of HSR stations (including the number of HSR stations, location advantages, and floor area) all show a positive correlation with ALE. (3) In the production stage, HSR reduces ALE by accelerating non-agricultural employment, and promotes ALE by improving agricultural technological innovation; In the benefit transformation stage, HSR promotes ALE by improving the development of rural e-commerce and agricultural product processing industry. (4) HSR has a higher promoting effect on ALE in major grain producing areas, western regions, and poverty-stricken counties. (5) HSR shows inter-regional spillover and intra-regional spillover effects. On the one hand, HSR will drive ALE in counties with a radius less than 20 km; on the other hand, HSR will also drive ALE in neighboring counties within 30 km. This study provides macro implications in transportation infrastructure construction for improving ALE.
农地利用效率低(ALE)是制约农业经济发展的一个重要问题。本研究探讨了高铁对中国县域农业土地利用效率的影响。基于共享投入的两阶段动态网络模型计算 ALE,分析高铁在生产阶段和效益转化阶段对 ALE 的影响。结果表明(1)高铁可以促进 ALE,在效益转化阶段对 ALE 的促进作用更大。(2)高铁的特征(包括高铁速度、通勤频率和不可替代性)以及高铁车站的特征(包括高铁车站数量、区位优势和建筑面积)均与 ALE 呈正相关。(3)在生产阶段,高铁通过加快非农业就业减少 ALE,通过提高农业技术创新促进 ALE;在效益转化阶段,高铁通过提高农村电子商务和农产品加工业的发展促进 ALE。(4) 在粮食主产区、西部地区和贫困县,高铁对 ALE 的促进作用更大。(5)高铁具有区域间溢出效应和区域内溢出效应。一方面,高铁会带动半径小于 20 千米的县的农业劳动生产率;另一方面,高铁也会带动半径在 30 千米以内的邻县的农业劳动生产率。本研究为交通基础设施建设提供了改善 ALE 的宏观启示。
期刊介绍:
Land Use Policy is an international and interdisciplinary journal concerned with the social, economic, political, legal, physical and planning aspects of urban and rural land use.
Land Use Policy examines issues in geography, agriculture, forestry, irrigation, environmental conservation, housing, urban development and transport in both developed and developing countries through major refereed articles and shorter viewpoint pieces.
