数字乡村建设对农业碳排放的影响和空间效应研究

Impact and Spatial Effects of Digital Rural Construction on Agricultural Carbon Emissions

摘要:

数字乡村建设是我国农业绿色低碳发展的关键驱动因子。本研究以中国2011-2021年31个省份（除港澳台）数据为研究样本，融合静态面板回归与动态空间计量方法，系统考察数字乡村建设对农业碳排放的直接影响、中介路径、非线性影响机制及空间效应等。结果表明：（1）推动数字乡村建设可有效抑制农业碳排放，其中农业技术进步是关键。（2）不同地理区域内，数字乡村建设对农业碳排放的影响呈非均衡性分布特征。“胡焕庸线”以东、非粮食主产区内数字乡村建设的碳减排效应更显著。（3）数字乡村建设对农业碳排放的影响存在农业产业集聚门槛，呈负向非线性特征。（4）数字乡村建设在降低农业碳排放方面存在空间溢出效应，且间接效应大于直接效应。因此，应大力推进数字乡村建设，以现代信息技术赋能农业绿色生产，助力农业碳减排高效发展。

Abstract:

Digital rural construction is a key driver for green and low-carbon agricultural development in China.Using data from 31 provinces(excluding Hong Kong, Macao, and Taiwan)in China from 2011 to 2021 as a research sample,this paper integrates static panel regression and dynamic spatial econometrics to systematically investigate the direct impacts,mediating paths,non-linear threshold mechanisms,and spatial spillover effects of digital rural construction on agricultural carbon emissions.Statistical analyses confirm that:(1) Advancing digital rural development can effectively reduce carbon emissions from agricultural activities,with technological advances in agriculture as a key mechanism.(2) Regional disparities exist in how digital rural initiatives affect farming-related carbon emissions. The carbon emission reduction effect of digital rural construction is more significant in the areas east of the ′Hu Huanyong Liné and in non-major grain-producing areas.(3)Dual agricultural industry agglomeration threshold exists in digital rural construction, with negative non-linear characteristics. (4)Digital rural construction has spatial spillover effects in reducing agricultural carbon emissions, and the indirect effect is greater than the direct effect. Therefore, the construction of digital village should be vigorously promoted, and modern information technology should be used to empower green agricultural production and help the efficient development of agricultural carbon emission reduction
