【摘要】 种植业生产集聚是实现农业现代化发展的重要路径。我国农业正处于向高质量发展转型的历史攻关期,受制于大国小农的现实国情,我国的农业发展仍然面临着生产经营分散、资源要素过度开发、应用技术落后等一系列问题,农业要实现更高质量的发展亟须寻找新动能。数字技术作为当前以及未来一段时间我国经济发展的重要驱动力,在不断渗透于农业领域的过程中也为促进种植业生产集聚提供了良好契机,因此本文主要探究数字技术如何对种植业生产集聚产生影响。具体工作如下:首先,在梳理和归纳相关文献的基础上,对数字技术以及种植业生产集聚的概念进行了界定,以明确本文的研究对象以及内容。其次,结合已有文献关于数字技术和种植业生产集聚两方面的研究,并立足于目前农村发展的现实情况,在理论层面阐释了数字技术影响种植业生产集聚的影响机制。再次,利用2012-2022年除港澳台、上海、西藏外我国29个省(市、自治区)的数据,测度了数字技术和种植业生产集聚发展水平,分析了我国数字技术以及种植业生产集聚的总体情况,并比较了我国不同地区、不同区域间数字技术和种植业生产集聚发展的情况。最后,基于理论分析和假设,构建基准回归模型、机制检验模型以及空间计量模型,实证检验了数字技术对种植业生产集聚的直接影响效应、作用机制、空间溢出效应以及区域异质性。结果表明:第一,数字技术能够显著提升种植业生产集聚水平,这一结论在经过内生性处理与稳健性检验之后仍然成立;第二,机制检验表明,数字技术能够推动土地流转以及深化农村人力资本进而促进种植业生产集聚。第三,空间计量回归结果表明,数字技术对种植业生产集聚具有空间溢出效应,且直接效应大于间接效应;异质性分析表明,数字技术对于东部、中部以及东北部地区的种植业生产集聚水平的提升有着明显的促进作用,对于西部地区作用效果不显著;从粮食产区与非粮食产区来看,数字技术对非粮食产区生产集聚的推动作用更大;进一步考察数字技术对各个省份粮、经两种作物生产集聚的促进作用,发现数字技术对经济作物生产集聚的促进作用强于粮食作物。因此,为实现种植业生产集聚,助力农业高质量发展,需要相关政府部门因地制宜促进数字技术协同发展,推动农村地区数字技术的发展与应用,打造农村数字化人才。该论文有图10幅,表21个,参考文献112篇更多还原

【Abstract】 Planting production agglomeration is an important path to realize the development of agricultural modernization.China’s agriculture is in the historical transition to high-quality development,subject to the actual national conditions of small-scale farming in a large country,China’s agricultural development is still facing a series of problems such as scattered production and operation,excessive development of natural resources,outdated technology application,etc.,and agriculture needs to find new momentum to achieve higher quality development.As an important driving force for China’s economic development at present and in the future,digital technology also provides a good opportunity to promote the production agglomeration of Planting in the process of continuously penetrating into the agricultural field.Therefore,this paper mainly explores how digital technology has an impact on the production agglomeration of planting industry,and the specific work is as follows:Firstly,on the basis of combing and summarizing the relevant literature,the concepts of digital technology and planting production agglomeration are defined,so as to clarify the research object and content of this paper.Secondly,combined with the existing literature on digital technology and planting production agglomeration,and based on the current reality of rural development,this paper theoretically explains the theoretical mechanism of digital technology affecting planting production agglomeration.Thirdly,using the data of 29 provinces(municipalities and autonomous regions)in China from 2012 to 2022,except Hong Kong,Macao,Taiwan,Shanghai and Tibet,this paper measures the development level of digital technology and planting production agglomeration,analyzes the overall situation of digital technology and planting production agglomeration in China,and compares the spatiotemporal characteristics of digital technology and the development of planting production agglomeration in different regions in China.Finally,based on theoretical analysis and assumptions,a benchmark regression model,a mechanism test model and a spatial econometric model were constructed to empirically test the driving effect,mechanism,spatial spillover effect and regional heterogeneity of digital technology on planting production agglomeration.The results show that,firstly,digital technology can significantly promote the increase of the production agglomeration level of planting industry,which is still valid after endogenous treatment and robustness test,and secondly,the mechanism test shows that digital technology can promote land circulation and deepen rural human capital,thereby promoting planting production agglomeration.Thirdly,the results of spatial econometric regression show that digital technology has a spatial spillover effect on planting production agglomeration,and the direct effect is greater than the indirect effect;heterogeneity analysis shows that digital technology has a significant promoting effect on the improvement of planting production agglomeration level in the eastern,central and northeastern regions,but has no significant effect on the western region;Through the promotion of the production agglomeration of the two crops,it is found that the promotion effect of digital technology on the production agglomeration of non-grain crops is higher than that of grain crops.Therefore,in order to achieve the agglomeration of planting production and help the high-quality development of agriculture,it is necessary for relevant government departments to promote the coordinated development of digital technology according to local conditions,promote the development and application of digital technology in rural areas,and create rural digital talents.更多还原
