长江中游粮食主产区数字乡村建设对耕地利用生态效率的影响
The Impact of Digital Rural Construction on Cultivated Land Use Eco-efficiency in Major Grain-Producing Regions in the Middle Reaches of the Yangtze River
摘要
Abstract
As a core driver of agricultural and rural modernization,digital rural construction is profoundly reshaping cultivated land use patterns and their eco-efficiency.Based on panel data of major grain-producing regions in the middle reaches of the Yangtze River(covering 31 prefecture-level cities in Hubei,Hunan and Jiangxi)from 2009 to 2023,this paper empirically examined the impacts and underlying mechanisms of digital rural construction on cultivated land use eco-efficiency via two-way fixed-effects model,threshold model,mediation effect model and spatial Durbin model.Heterogeneity analysis was further conducted to explore differentiated impacts of digital rural construction on cultivated land use eco-efficiency.The empirical results showed that:digital rural construction exerted a significantly positive promoting effect on cultivated land use eco-efficiency with a double-threshold nonlinear characteristic,which survived multiple robustness tests.Mediation and spatial spillover analyses revealed that digital rural construction indirectly improved cultivated land use eco-efficiency by boosting digital finance penetration,advancing farmers'digital literacy,and accelerating agricultural industrial upgrading.In addition,digital rural construction could collaboratively improve the cultivated land use eco-efficiency of neighboring regions through spatial spillover effects.Heterogeneity analysis results confirmed significantly positive effects in both plain and non-plain regions,with stronger marginal gains observed in plain areas.Specifically,digital rural construction had significant positive effects on factor inputs and desirable agricultural outputs,and significant negative effects on undesirable outputs,and its marginal promoting impact intensified sequentially at higher quantiles of cultivated land use eco-efficiency.Accordingly,this papers puts forward targeted policy recommendations:promoting differentiated digital rural construction across subregions,crossing critical development thresholds,smoothing intermediate transmission channels to strengthen digital empowerment,establishing interregional coordination systems to amplify spatial spillover gains,and optimizing factor allocation for low-carbon and green cultivated land use.These measures aims to advance the coordinated green transformation and modernization of agriculture in major grain-producing regions in the middle reaches of the Yangtze River.关键词
