| Summary: | 碩士 === 國立高雄第一科技大學 === 運輸與倉儲營運系 === 89 === Based on the characteristics of digital products and service, this paper employs the classical economic analysis method to explore the differences between digital products and physical products. Furthermore, we try to discuss the assumptions proposed by the past literature from aspects of demand, supply, and network externality respectively.
Prior studies have reached some conclusions of the characteristics of digital products and service. These characteristics include experienced goods, indestructibility, transmutability, reproducibility, high fixed costs but low marginal costs, almost negligible variable costs, time value, customization, economic of scale, increasing return, network externalities, and the value of a network goes up on exponential rate as the users increased, etc. According to characteristics, we find that digital products and services which is closely related with time value, have obvious difference with physical products in the utility curve and demand curve, but slight difference in the products curve and costs curve, and variable costs can’t be negligible. In the other hand, digital products and services which is not closely related with time value, have obvious difference with physical products in the product curve and cost curve, we further find that economy of scale of digital products and services, is not only in the effect of supply but also the effect of demand.
