This paper takes new consumption phenomena in the digital media-dominated polymedia environment as the object of study to review the theoretical history of “mediatization,” and explores new consumption’s emergence, essence, and related issues systematically through deductive reasoning. More specifically, this paper is to first interpret the mediatization theory and then analyze two dimensions(i.e., the formation of mediatized consumption and the resultant reinvention of practice rules) from the perspective of media affordances. On this basis, we conclude mediatized consumption’s essence, forms, and practice rules. This study indicates that new consumption is essentially mediatized consumption, which concerns “media-shaped consumption” and “consumption-shaped media,” and that new consumption has two representations;consumption-oriented media and banal consumption. Media affordances make new consumption fields human-oriented, connecting “people” and “things,” and are becoming a major contributor to the formation of mediatized consumption. Thus, the practice rules concerning “people, goods, and fields” in the new consumption sector are reinvented;the social interactions in the “middle region” are highlighted;the imaginative, narrative, and social characteristics of goods are emphasized;and the cross-field integration of consumption is realized.展开更多

It is a practical approach to use the guaranteed rate with statistical characteristics to analyze the output coefficient of new energy. However, there is a lack of analysis and demonstration on the value of the new energy output guaranteed rate. To solve this problem, a selection method for the new energy output guaranteed rate considering optimal energy storage configuration is proposed. First, the influence of the new energy output guaranteed rate on the new energy output coefficient is analyzed. Secondly, with the goal of minimizing the comprehensive costs, an optimal configuration model of energy storage based on the output guaranteed rate of new energy is constructed, and particle swarm optimization is used for the optimization solution. Then, according to the optimal energy storage configuration results under different guaranteed rates, a reasonable new energy output guaranteed rate is determined by maximizing the comprehensive benefits obtained from energy storage. Finally, an example applied to the power grid in an area of Guangdong in Southern China is provided to illustrate the effectiveness of the proposed method.展开更多
