Abstract:In the background of cultivating top-ranking sci-tech journals, This paper focusing on sci-tech journals and regional sci-tech innovation, by means of online research, literature research and data analysis, presents the construction and regional distribution of top-ranking sci-tech journals, analyzes the linkage between sci-tech journals and key elements of science and technology innovation, to explore the service of sci-tech journals for technological innovation. Then taking Hunan Province as an example, analyze the achievements and problems of support policies on top-ranking sci-tech journals construction to service science and technology innovation for individual provincial-level administrative regions. The research presents: the distribution of top-ranking sci-tech journals in various regions is uneven. There existed significant correlations between sci-tech journals and elements of regional innovation.Some problems exist during the policies implementation supporting the development of sci-tech journals to service science and technology innovation, such as the discourse power of the dominant subjects is not enough, and the scale of the top-ranking sci-tech periodicals is small; the effect of service industry is not significant, and the output of scientific and technological achievements is not enough; the linkage of scientific and technological innovation factors and the periodical policy support is not enough. Finally, based on data statistics and case analysis,this research proposes suggestions from three aspects of strengthening support for science and technology policies, expanding the scale of first-class sci-tech journals, promoting the output of high-quality sci-tech achievements, which would provide certain reference for regions to strengthen the construction of sci-tech journals and assist in the development of science and technology innovation.
