Based on the extended Hotelling linear city model this paper constructs a theoretical framework for the equilibrium analysisof online and offline consumption it is conducive to promoting the deep integration of online and offline consumption. The paper findsthat time cost and distance cost are the reasons for the coexistence of online and offline consumption after incorporating the time-costfunction the offline demand will increase with the increase of the time spent on online consumption the cost of service experience foroffline demand has a positive elasticity but the size of the elasticity depends on the combined effect of related parameters the degreeof price sensitivity of offline demand is moderated by offline service differences. Based on the above conclusions this paper focuses onhow to promote the deep integration of online and offline consumption and puts forward relevant policy recommendations to build thecomparative advantages of online and offline consumption.
