差異化網路服務之價值分析

This study analyzes the demand for internet services with demand characteristics and endogenized quality of services (QoS, including supply-side (technology) perspectives of internet service quality, e.g. www site technology builder, compatibility, switching type, switching capabilities, bandwidth, mobility, transmission protocols, traffic characteristics; and demand-side features of QoS, e.g. content, interactivity, usability, aesthetics, content marketing, etc.). We identify key parameters for user’s perception of service quality: What QoS dimensions truly matter for overall quality perception? Quantify correlation between application type and service demand. And we study the differentiated network services and the structure of the usage-quality combination to measure economic value which users place on identified quality dimensions. This study applies network services offered today in Taiwan to reveal the quality-technology combinations. The framework built up in this study can be used to forecast the future demand and characteristics for new internet services and network innovation. We explore to what extent the demand and scale of network innovation of internet product and services could be induced by technological changes or new technological development, and understand how network services interact with overall firm activities. The purpose of this paper is to match the QoS and technology capacity in the network with the market needs and to model the network services with differentiated service quality and technology capacity. The contribution of this paper is threefold. This study makes it possible to analyze disaggregate demand for network services that make implementation of optimal nonlinear pricing feasible. This study assesses how heterogeneous consumers value quality-differentiated internet services and modeling consumers utilization behavior. And this paper develops an econometric model of internet users' preferences over internet service attributes that calibrates unobserved preference heterogeneity. To this end, a stochastic preference model is proposed and estimated to measure economic value that users evaluate on identified quality dimensions on data from Taiwan existed network services. And the framework built up in this study can be used to forecast future demand and characteristics for new internet services and product innovation. 表 C011 共 2 頁第 2 頁 Taiwan is known as ICT competitiveness in that it is ranked the seventh in the world and the second in Asia according to the Networked Readiness Index (NRI) documented by World Economic Forum (WEF). In order to promote industrial growth via technological innovation, the government needs to take Taiwan’s technological advantage, develop service innovation, science and technology, and the knowledge-based strategies. In a broader research agenda, this study is to cultivate network innovations and search innovative business model to help the enterprise in different industries to meet the emerging challenges. And the goal is to provide policy implications for macro-policy environment, firm-strategies, and firm-level policy competency.
