Abstract: The technical and economic characteristics of each section in power industry are essential to the power system reform. With the development of distribution technology and the application of intelligent distribution technology, the technical characteristics of the distribution network have changed significantly. In order to explore the impacts of technological developments on the natural attributes of the distribution network, this paper delves into the natural monopoly attributes of the distribution network, including the sub-additivity of costs, scale economy and scope economy. On this basis, this paper analyzes the impacts of the distribution network intelligence and automation technology on the scale economy and scope economy of the distribution network, which can provide decision-making reference for the reform measures of electric grid section as well as the incremental distribution network reform.

Key words: power system reform, intelligent distribution technology, natural monopoly attribute, scale economy, scope economy
