要素错配对农业生态高质量发展的影响——以粮食主产区地级市为例

Impact of Factor Misallocation on Agricultural Ecological High-Quality in Main Grain Producing Areas——A Case Study of Prefecture-Level Cities

为探究粮食主产区地市层面要素错配对农业生态高质量发展的影响,运用空间计量模型,以2004~2020年154个地级市的面板数据为样本展开分析。研究表明,地市层面要素错配不断下降而农业生态高质量发展水平有所提升,且两者均存在空间差异。要素错配对本地和邻近地市农业生态高质量发展的抑制作用具有时空异质性,该结论经过一系列检验依然稳健。机制检验发现,农业产业升级可弱化要素错配对农业生态高质量发展的负向影响,但农业科技进步却强化了该负向影响且存在非线性特征。研究结论丰富了农业生态高质量发展影响因素的理论文献,为纠偏要素错配,制定农业高质量发展政策提供了实证借鉴。

To explore the impact of factor misallocation at the municipal level of the high-quality development of agricultural ecology in major grain producing areas,spatial econometric models were used to analyze the panel data from 154 prefecture-level cities from 2004 to 2020.The results showed that the factor misallocation at the municipal level had been continuously decreasing,while the level of high-quality development of agricultural ecology had improved,and both had spatial differences.The inhibitory effect of factor misallocation on the high-quality development of agricultural ecology in local and adjacent cities had spatiotemporal heterogeneity,and this conclusion remained robust after a series of tests.The mechanism test found that agricultural industry upgrading could weaken the negative impact of factor misallocation on the highquality development of agricultural ecology,but agricultural science and technology progress strengthened this negative impact and had non-linear characteristics.The conclusion enriched the theoretical literature on the influencing factors of high-quality agricultural ecological development,and provided empirical references for correcting factor misallocation and formulating policies for high-quality agricultural development.
