摘　　要：随着5G、智能传感、数字孪生、物联网等数字技术逐步商用,万物互联将是大势所趋,实体经济与网络经济彼此分离的状况被打破。届时,“经济人”利己动机将无法解释上网免费、开源共享、网络协同等利他的“异常”消费行为。为此,在深度剖析虚实融合网络经济的消费特征基础上,根据梅特卡夫定律构建了基于虚实融合网络价值的新型效用函数,并分析其独特的边际效用变动规律及成因。研究发现,虚实融合网络经济的产品形态表现为虚实融合的实体镜像,效用函数表达为发散的二次型函数,效用最大化条件下消费量与价格之间呈正比关系。此外,受网络价值、网络外部性以及信息产品准公共性的三重作用,虚实融合网络产品具有明显的反稀缺性特征,从而导致其消费活动遵循边际效用递增规律。研究结论有助于重构虚实融合网络时代的新型消费理论,并为相应的产业政策调整提供学理依据。With the gradual commercialization of technologies such as 5G,intelligent sensing,digital twins,and the Internet of Things,the interconnection of everything will become a trend,and the separation of the real economy and the network economy will be broken.At that time,the egoistic motivation of"economic people"will not be able to explain altruistic"abnormal"consumption behaviors such as free internet access,resource sharing,and network collaboration.Therefore,on the basis of in-depth analysis of the consumption characteristics of virtual-real fusion network economy,a new utility function based on virtual-real fusion network value is constructed according to Metcalfe's law,and its unique marginal utility variation law and causes are analyzed.It is found that the product form of virtual-real fusion network economy is the entity mirror image of virtual-real fusion,the utility function can be expressed as a divergent quadratic function,and there is a proportional relationship between consumption and price under the condition of utility maximization.In addition,due to the triple effects of network value,network externality and quasi publicity of information products,virtual-real fusion network products have obvious anti scarcity characteristics,which leads to their consumption activities following the law of increasing marginal utility.The research conclusion is helpful to reconstruct the new consumption theory in the era of virtual-real fusion network,and provides scientific basis for the corresponding industrial policy adjustment.
