【摘要】 在数字时代,数字经济已成为当前我国经济发展的重要着眼点,数字中国、数字政府、数字社会战略的提出足以凸显出数字化在经济、社会发展中的重要地位。2021年,国务院关于印发“十四五”数字经济发展规划的通知中明确了当前数字经济发展的重点工作是大力推动产业数字化转型,全面深化重点产业的数字化转型,推动实现产业园区和产业集群的数字化转型。企业作为数字经济发展的微观主体,推动企业数字化转型对数字经济发展战略的实现至关重要。现有文献重点研究了制造业或全行业上市公司的数字化转型所产生的的微观效应,但对农业行业的数字化转型效果问题关注较少,并且针对数字化转型的微观效应这一问题学术界仍有不同的声音。数字化转型本质上是一场技术革命,需要企业投入大量的资金、人力和物力。相较于第二、三产业来说,农业行业的数字化转型困难重重,甚至“雪上加霜”,数字化转型的效果是否同制造业或高新技术行业一样对企业价值产生立竿见影的提升效果需要验证。因此,研究农业上市公司数字化转型与企业价值之间的影响关系,以及研发投入在二者关系之间存在的作用,不仅能够坚定农业企业进行数字化转型的信心和决心,还可以为农业企业的数字化转型提供一定指导,助力农业产业数字化发展。本文通过梳理国内外相关文献,以农业行业为视角,探讨了数字化转型、研发投入和企业价值三者之间的影响关系。本文的研究内容主要包括三方面:首先,以价值创造理论和价值链理论为依据深入分析了农业企业数字化转型、研发投入和企业价值之间的内在逻辑关系,并据此提出本文的研究假设;其次,以2014-2021年60家A股农业上市公司和新三板上市公司为样本数据构建固定效应模型,进行实证分析,对本文的研究假设进行验证;最后,依据本文的研究结论提出相应对策建议。本文的研究结论为:(1)数字化转型对农业企业价值的影响存在明显滞后性,农业企业在进行数字化转型后的第三年才会对企业价值产生促进作用。(2)研发投入在数字化转型提升企业价值的关系中存在正向强化作用。(3)成熟型和非国有农业企业的数字化转型相较于成长型企业、国有企业能够显著增加企业价值。本文的创新点主要体现在两方面,一是研究结论方面的创新。本文以农业行业为研究视角,利用A股和新三板上市的农业企业相关数据验证了数字化转型对农业企业价值的提升作用存在滞后性,补充和丰富了数字化转型经济效应的研究理论,并有助于提高实证检验结果的科学性和可靠性。二是验证研发投入在其中存在正向调节作用。本文从调节效应角度出发,明确了研发投入在数字化转型影响企业价值的关系中起到正向调节效应,拓展了企业数字化转型和企业价值影响因素相关方面的研究领域。更多还原

【Abstract】 In the digital era,digital economy has become an important focus of China’s current economic development,and the proposal of digital China,digital government,and digital society strategies highlights the important position of digitalization in economic and social development.In 2021,the notice of The State Council on the issuance of the "14th Five-Year Plan" digital economy development Plan clarified that the current focus of digital economy development is to vigorously promote the digital transformation of industries,comprehensively deepen the digital transformation of key industries,and promote the digital transformation of industrial parks and industrial clusters.As the micro-main body of the development of digital economy,the promotion of digital transformation of enterprises is crucial to the realization of the development strategy of digital economy.The existing literature focuses on the micro effects of the digital transformation of the manufacturing industry or the Shanghai-Shenzhen A-share listed companies in the whole industry,but pays little attention to the effect of the digital transformation of the agricultural industry,and there are still different voices in the academic circle on the micro effects of digital transformation.Digital transformation is essentially a technological revolution that requires enterprises to invest a lot of capital,manpower and material resources.Compared with the second and third industries,the digital transformation of the agricultural industry has many difficulties,and even "worse",and whether the effect of digital transformation is the same as that of manufacturing or high-tech industries to produce immediate improvement of enterprise value needs to be verified.Therefore,studying the relationship between the digital transformation of listed agricultural companies and enterprise value,as well as the role of R&D investment in the relationship between the two can not only strengthen the confidence and determination of agricultural enterprises to carry out digital transformation,but also provide certain guidance for the digital transformation of agricultural enterprises and help the digital development of agricultural industry.By combing relevant literature at home and abroad,this paper discusses the relationship among digital transformation,R&D investment and enterprise value from the perspective of agricultural industry.The research content of this paper mainly includes three aspects: First,based on the value creation theory and the value chain theory,this paper deeply analyzes the internal logical relationship between the digital transformation of agricultural enterprises,R&D investment and enterprise value,and puts forward the research hypothesis based on this.Secondly,based on the sample data of 60 A-share agricultural listed companies and NEEQ listed companies from 2014 to 2021,A fixed-effect model was constructed to conduct empirical analysis and verify the research hypotheses of this paper.Finally,according to the conclusions of this paper,the corresponding countermeasures and suggestions are put forward.The conclusions of this paper are as follows:(1)There is a significant lag in the impact of digital transformation on the value of agricultural enterprises,and agricultural enterprises will not have a promoting effect on the value of enterprises until the third year after the digital transformation.(2)R&D investment has a positive strengthening effect on the relationship between digital transformation and enterprise value enhancement.(3)The digital transformation of mature and non-state-owned agricultural enterprises can significantly increase enterprise value compared with growth enterprises and state-owned enterprises.The innovation of this paper is mainly reflected in two aspects,one is the innovation of research perspective.From the perspective of agricultural industry,this paper analyzes the impact of digital transformation on the value of agricultural enterprises by using the relevant data of A-share and NEEQ listed agricultural enterprises,broadens the research field of the economic effect of digital transformation,and helps to improve the scientific and reliability of empirical test results.The second is the proof of the moderating effect of R&D investment.From the perspective of regulatory effect,this paper clarifies the regulatory effect of R&D investment on the relationship between digital transformation and enterprise value,enriching the research results related to the factors affecting enterprise digital transformation and enterprise value.更多还原
