Research On Current Situation And Trend Of High-speed Railway Economy Based On Text Mining

Since 2008,China's high-speed rail has entered a rapid development.The domestic and international attention to the economic effects of high-speed rail has increased.Even in a large number of historical period,a large number of journal articles have emerged.In the new research field,it is of great significance to grasp the research history and context based on the scientific literature,and to sort out the research results so as to deeply understand the definition of high-speed rail economy and anticipate future research trends.This thesis takes the research literature of high-speed rail economy at home and abroad as the research object,collects the national policy documents related to high-speed rail economy for ten years as the initial text,carries out word segmentation,word cloud display and word frequency analysis and outputs high-frequency subject words,and searches for ten years based on output subject words.The high-quality high-speed rail economic related journal literature is the target literature of the research.After the preliminary analysis of the age,author,journal source,issuing organization and high-cited papers,the content of the target literature is analyzed and visualized by CiteSpace software.The keywords of the target document are used to present the co-occurrence network and clustering map,time zone view and mutation word detection.Then,through the programming language Python,the potential topic mining of the corpus formed by the LDA model on the target document abstract is realized,and the current domestic high-speed rail economy research is obtained.The hot topic,in the end,combined with the research progress of the past decade,the research direction,the combing and presentation of the results,further explored the research stage,development trend and definition of the high-speed rail economy.From the empirical results,it is found that the high-speed rail economy is forming a mature system,and in the continuous research process,it has a certain degree of intersection with other economic disciplines.The research process of the high-speed rail economy can be roughly divided into the construction of high-speed rail industry and The germination period dominated by equipment manufacturing research,the development period focusing on traffic accessibility,and the three initial stages and six hot topics that are inseparable from transport economics in the promotion period of research combined with behavioral economics theory,will be in the future.Entering the maturity period under the guidance of a richer theory.Combining with the original definition of high-speed rail economy,it is believed that the high-speed rail economy is not a simple combination of high-speed rail and economics.The high-speed rail economy is the economic form driven by the industrial chain brought by the new mode of transportation of high-speed rail.The connotation is to meet the transportation service belt in the high-speed rail industry.The economic effects of infrastructure and engineering technology are derived from the economic effects of traffic accessibility along the region and the tertiary industry.
