摘要
数字基础设施建设为农业绿色发展赋予了新动能,明晰数字基础设施与农业绿色全要素生产率(GTFP)之间的关系,对于推动农业高质量发展具有重要意义。文章基于2012—2022年中国30个省份的面板数据,采用熵值法和SBM-GML模型分别测算了数字基础设施建设和农业GTFP水平,并运用双向固定效应模型、中介效应模型及门槛效应模型等方法多维度实证考察数字基础设施对农业GTFP的影响及作用机制。研究发现:数字基础设施建设能够显著提高农业GTFP;数字基础设施建设可以通过提高农业绿色技术效率进而提高农业GTFP,还可以通过促进数字普惠金融发展和带动城乡市场对接间接提高农业GTFP;进一步地将农村人力资本设定为门槛变量,数字基础设施建设与农业GTFP呈现出边际效应递增的非线性趋势;数字基础设施建设对农业GTFP的提升效应在“胡焕庸线”东南侧、市场化水平高、环境规制力度强的地区更加明显。鉴于此,应加大数字基础设施建设投入,驱动农业绿色发展;促进数字普惠金融发展,深化城乡市场对接;提升农村人力资本水平,强化人才支撑作用;聚焦区域差异特性,因地制宜制定配套政策。
The construction of digital infrastructure has given new momentum to the green development of agriculture,and it is of great significance to clarify the relationship between digital infrastructure and agricultural green total factor productivity(GTFP)to promote the high-quality development of agriculture.Based on the panel data of 30 provinces in China from 2012 to 2022,this paper uses the entropy method and SBM-GML model to measure the level of digital infrastructure construction and agricultural GTFP,respectively,and comprehensively uses the two-way fixed effect model,the intermediary effect model and the threshold effect model to empirically investigate the impact and mechanism of digital infrastructure on agricultural GTFP in multiple dimensions.The results show that the construction of digital infrastructure can significantly improve agricultural GTFP.Mechanism analysis shows that digital infrastructure construction can improve agricultural GTFP by improving the efficiency of agricultural green technology,and can also indirectly improve agricultural GTFP by promoting the development of digital inclusive finance and driving the connection between urban and rural markets.Furthermore,taking rural human capital as the threshold variable,the digital infrastructure construction and agricultural GTFP show a nonlinear trend of increasing marginal effect.The promotion effect of digital infrastructure construction on agricultural GTFP is more obvious in the southeast of the"Hu Huanyong Line",and in regions with high marketization level and strong environmental regulation.In view of this,we should increase investment in digital infrastructure construction to drive the green development of agriculture,promote the development of digital inclusive finance and deepen the connection between urban and rural markets,improve the level of rural human capital and strengthen the supporting role of talents,focus on the characteristics of regional differences,and formulate supporting policies according to local conditions.
