本文在明确30个省份农业农村数字经济和农业碳排放效率现状特征的基础上探讨了二者之间的关系,同时分析了农村人力资本水平在其中的门槛作用以及数字经济对农业碳排放效率影响的空间溢出效应。研究发现:(1)中国各省份农业碳排放效率和农业农村数字经济发展水平均处于稳步上升态势。样本考察期内,除上海之外,其余29个省份 农业碳排放效率均呈上升趋势且以青海增幅最大;所有省份农业农村数字经济发展水平均表现出增长态势且以浙江增幅最大。(2)数字经济对农业碳排放效率的影响存在"N"型非线性关系,即农业碳排放效率会随着数字经济发展水平的提高表现出"先增、后降、再增"的三阶段特征,且最终表现为促进作用。(3)数字经济对农业碳排放效率的影响存在农村人力资本门槛,且始终为正向非线性作用。(4)数字经济对农业碳排放效率的影响存在空间溢出效应,本地农业碳排放效率会随邻近地区数字经济发展阶段的变化而受到不同的影响。
The Impact of Digital Economy on Agricultural Carbon Emission Efficiency:Based on Threshold Effect and Spatial Spillover Effect Test
This paper explores the relationship between the digital economy in agriculture and rural areas and the efficiency of agricultural carbon emissions in 30 provinces on the basis of clari-fying their current characteristics,and also analyses the threshold role of rural human capital and the spatial spillover effects of digital economy on agricultural carbon emission efficiency.The find-ings are as follows:(1)Agricultural carbon emission efficiency and the development level of agri-cultural and rural digital economy are both on a steady rise in all Chinese provinces.During the sample period,except Shanghai,other 29 provinces show an increasing trend in agricultural carbon emission efficiency,with Qinghai showing the largest increase.All provinces show an increasing trend in the development level of agricultural and rural digital economy,with Zhejiang showing the largest increase.(2)The impact of digital economy on agricultural carbon emission efficiency has a positive"N"type non-linear relationship,that is,agricultural carbon emission efficiency will show a three-stage characteristic of"first increase,then decrease,and finally increase"with the devel-opment of digital economy,and eventually it will show a promoting effect.(3)The influence of dig-ital economy on agricultural carbon emission efficiency has a threshold of rural human capital,and the effect is always positive and non-linear.(4)Digital economy has a spatial spillover effect on agricultural carbon emission efficiency.Local agricultural carbon emission efficiency will be affected differently by the change of development stage of digital economy in neighboring regions.
