摘要:

以县域面板数据为研究样本,利用卫星监测的夜间灯光数据表征城市化水平,就城市化对地区农业机械化水平的影响及其作用机制进行考查,并检验不同地形下城市化对农业机械化水平的异质性影响。研究发现:就全国整体而言,城市化发展促进了地区农业机械化水平的提高,稳健性检验结果强化了这一结论。分地形样本显示,平原、丘陵地区的城市化发展引起农业机械化水平的提高,而山区的城市化发展引起农业机械化水平的下降。影响机制分析表明,农村劳动力转移、种植结构调整与农村交通设施建设是城市化推进农业机械化的传导途径。

关键词: 城市化, 农业机械化, 夜间灯光数据, 地形

Abstract:

In the present study, the county-level panel data of China, as well as the lighting data at night monitored by satellite characterizing the urbanization level, was used to empirically investigate the impact of urbanization level on the agricultural mechanization level in China and to explore its action mechanism. Besides, the heterogeneous impacts of urbanization on the development of agricultural mechanization under different terrain were also tested. It was found that with the improvement of urbanization level, the agricultural mechanization level was improved, and the robustness results strengthened this conclusion. Urbanization level in plain and hilly areas had positive effect on agricultural mechanization level, yet urbanization level in mountainous areas resulted in a negative impact on the agricultural mechanization level. Analysis of impact mechanism revealed that the transfer of labor force, the changes of planting structure and the improvement of rural transportation facilities were the main transmission ways for urbanization to promote the development of agricultural mechanization level.

Key words: urbanization, agricultural mechanization, nighttime lighting data, terrain
