数字经济时代微观经济理论的探索与思考

Exploration and reflection on microeconomic theory in the digital economy era

为了厘清数字经济时代传统微观经济学理论的适用性问题,揭示微观经济学理论革新的方向和实践中的应用,旨在构建一个更加符合数字经济特点的微观经济学理论框架。采用文献分析、理论分析和案例研究相结合的方法,着重将微观经济学理论框架中的供求定理、消费者行为、生产者决策、市场结构和外部性理论五大部分,置于数字经济时代背景下进行深入剖析。研究发现,数字经济时代的供求定理需要考虑基于大数据、人工智能的供给特征和消费者需求逻辑,以及平台企业的网络外部性和规模经济效应;消费者行为呈现出优化、升级、多样化和个性化的特征,以及非占有式的分享消费逻辑,并且可能产生选择过载;生产者决策需要运用人工智能技术来匹配产供销大数据,实现数据智能化,提高生产效率和创新能力;市场结构呈现出分层式垄断竞争的特点,需要采取新的监管政策和治理机制,维护市场秩序和社会福利;外部性理论需要分析数字经济带来的正外部性和负外部性,处理信息问题和产权问题,注重维护数据隐私和网络安全。研究表明,数字经济对微观经济学提出了一系列新挑战,要求理论和实践的创新与调整,通过更新理论框架、引入新的分析方法,微观经济学能够更好地理解和适应数字经济的发展,为理解数字经济时代的经济学变革提供了一定的参考和启示。

To clarify the applicability of traditional microeconomic theory in the digital economy era,uncover the direction of microeconomic theory innovation and its practical application,and build a theoretical framework that aligns more closely with the characteristics of the digital economy,this paper employs literature analysis,theoretical analysis,and case study methods.It focuses on the five major components of the microeconomic theory framework-supply and demand theorem,consumer behavior,producer decision-making,market structure,and externality theory-within the context of the digital economy for an in-depth analysis.The study reveals that in the digital economy era,the supply and demand theorem must consider supply characteristics and consumer demand logic based on big data and artificial intelligence,as well as network externalities and economies of scale of platform enterprises.Consumer behavior is characterized by optimization,upgrading,diversification,personalization,non-possessive sharing consumption logic,and may lead to choice overload.Producer decision-making must leverage artificial intelligence to match production,supply,and marketing big data,achieve data intelligence,and enhance production efficiency and innovation capabilities.Market structure exhibits characteristics of hierarchical monopolistic competition,necessitating new regulatory policies and governance mechanisms to maintain market order and social welfare.Externality theory needs to examine the positive and negative externalities brought by the digital economy,address information problems and property rights issues,and focus on maintaining data privacy and network security.The study indicates that the digital economy introduces a series of new challenges to microeconomics,necessitating theoretical and practical innovations and adjustments.By updating the theoretical framework and introducing new analytical methods,microeconomics can better understand and adapt to the developments of the digital economy,offering valuable insights and inspirations into the economic changes of the digital economy era.
