摘要
[目的]经济集聚对农业环境效率具有双重影响,研究经济集聚与农业环境效率的关系对于改善中国农业生产环境、促进农业高质量发展意义重大.[方法]基于2001-2020年中国280个地级及以上城市的面板数据,通过构建非线性模型实证分析了经济集聚对农业环境效率的影响及作用机制.[结果]①经济集聚对农业环境效率的影响呈现出倒"U"型特征,该结论在进行一系列稳健性检验后依然成立.②经济集聚对农业环境效率的影响在环境规制强、地形起伏小的地区更加显著.③城市创新能力和农村人力资本水平是经济集聚影响农业环境效率的两个渠道.④进一步研究发现,经济集聚对周边地区农业环境效率在空间上呈现出正"U"型影响.[结论]研究为提高农业环境效率提供了一定的政策依据和经验参考.
Abstract
[Objective]Economic agglomeration has a dual impact on agricultural environmental effi-ciency,and the study of the relationship between economic agglomeration and agricultural environmental efficiency is of great significance for improving China's agricultural production environment and promot-ing high-quality agricultural development.[Method]Based on the panel data of 280 prefecture-level and above cities in China from 2001 to 2020,this paper empirically analyzes the impact of economic agglomeration on agricultural environmental efficiency and the mechanism of its action by constructing a nonlinear model.[Result]①The impact of economic agglomeration on agricultural environmental efficiency is characterized by an inverted"U"shape,and the conclusion still holds after a series of robustness tests.②The impact of economic agglomeration on agri-environmental efficiency is more significant in areas with strong environmental regulations and small topographic relief.③Urban innova-tion capacity and rural human capital level are two channels through which economic agglomeration affects agri-environmental efficiency.④Further research finds that economic agglomeration has a posi-tive"U"-shaped impact on the spatial efficiency of agricultural environment in the neighboring areas.[Conclusion]The research in this paper provides certain policy basis and empirical references for im-proving agro-environmental efficiency.
