Smart grids (SGs) have been widely recognized as an enabling technology for delivering sustainable energy transitions. SGs have a positive effect on the development of the world economy and society. SG construction plays an important role in responding to global climate change and promoting the sustainable development of the world economy and society. Under such a background, this paper attempts to investigate patent collaborations of the SG field in China. Based on the application data of collaborative patents from State Intellectual Property Office (SIPO) in China, this study employs complex network theory and social network analysis (SNA) method and conducts in-depth research on the patent collaboration network of SG field in China. The trend of patent collaboration was examined, the collaboration network of SG-related patents was investigated, the network characteristics, and the network structure were also explored. The results show that the proportion of enterprises participating in patent collaboration is relatively large for SG field in China, the percentage of collaboration relationships formed by different patent applicants varies greatly, and that the State Grid Corporation of China (SGCC) plays an important role in patent collaboration in SG field currently. It can also be found that patent collaboration is an effective form of cooperative innovation among different entities. Finally, three suggestions are provided in response to the existing problems.

The article considers the principles of systematization of the outer world in the author's individual consciousness of I.A. Bunin and presents the description of personal imaginative nominations of elemental phenomena of nature. The research is based on the synthesis of traditional and modern methods of analysis for realization of a literary word: component, discourse-text analysis of names, as well as cognitive-hermeneutic text analysis, which made it possible to set up a correspondence existing between the units of the text, the information coded by them and the mental structures behind this information, or their elements by studying the character of the connections between them. The analyzed ways of verbalization of the author's meanings at the level of contact and distant connections allow to reveal the cognitive-mental and emotive spheres of the writer's consciousness, and also to interpret the phenomenon of Bunin's Universe as a complex phenomenon that determines its uniqueness and originality in Russian literature. It is noted that the textual realization of words in literary discourse leads to the integration of various aspects of reality and recreates the author's perception of the world, based on the inseparable, interpenetrating unity of the objective and subjective, the logical and sensual, the rational and emotional. The presented paradigm of the images of wind elicits the properties of its prototype and explicates new properties and attributes of the denotation on the basis of its systemic and non-systemic relationships arisen in the author's consciousness. On the basis of the considered complex of associativesingsof the element of wind, the authors reveal Bunin's understanding of the semantic multidimensionality of being, the complexity and versatile relations between man and the world.

The study of grammatical categories in the artistic context from the position of anthropocentrism is a topical issue in modern linguistics. The greatest interest from the point of view of the relationship "language" -"man" is the category of Russian language gender, which has great stylistic resources and can be motivated extra-linguistically. In this paper, the authors analyze personification as the way of gender grammatical category expression in the artistic context of Russian writer and poet works. In the article the authors consider the linguistic picture of the world, in the creation of which the embodiment is important, the semantic-grammatical properties of which are determined by the ambivalence of animacyinanimation category. Gender denotation occupies a special place in the interpretative structure of gender category, which presupposes a nominative significance of neutral gender nouns as a result of personification, stylization and the expression of symbolic meaning. Thus, extralinguistic possibilities of gender category are expanded, which are realized mainly in artistic speech. The authors of the article conclude that the grammatical personification of gender category as a vivid means of expression, expressiveness, imagery and emotionality is associated with a person's thinking, his worldview, psychological characteristics; and this judgment allows us to consider the category of gender not only as a morphological one, but also as a logical, mental category.
