数字经济对农产品出口贸易的影响——基于省级面板数据的经验研究

The Impact of Digital Economy on Export Trade of Agricultural Products——An Empirical Study Based on Provincial Panel

基于我国2011—2020年的省级面板数据,对数字经济影响农产品出口贸易的总效应、区域异质性和门限效应进行了实证检验。研究发现:数字经济可以扩大农产品出口规模,提高农产品出口技术复杂度,在考虑了内生性后结论依然成立;数字经济对农产品出口的影响存在区域异质性,对中部地区的促进作用最强,东部地区次之,对西部地区的影响并不显著;数字经济、农村人力资本与农产品出口之间存在非线性门限关系,农村人力资本水平越高,数字经济对农产品出口的促进作用越强。

Based on the panel data at the provincial level of China from 2011 to 2020,this paper empirically tests the total effect,regional heterogeneity and threshold effect of digital economy on agricultural exports.The conclusions are as follows:first of all,digital economy can expand the scale of agricultural products export and improve the technical complexity of agricultural products export,which is still valid after considering the endophytism;then,there is regional heterogeneity in the impact of digital economy on the export of agricultural products,which has the strongest promoting effect on the central region,then on the eastern region,and having no significant impact on the western region;finally,there is nonlinear threshold relationship among digital economy,rural human capital and agricultural products,the higher the rural human capital,the stronger the role of digital economy in promoting the export of agricultural products.
