【摘要】 "一带一路"对世界经济及我国民生的发展和改善发挥了积极作用,自"一带一路"实施以来,中国多个相关省、自治区、直辖市围绕自身特点积极布局,发布了一系列地方性"一带一路"相关政策。文章基于关键词词频—逆文件频率(TF-IDF),对中国"一带一路"沿线各省、自治区、直辖市在2014—2020年颁布的"一带一路"相关的政策文本进行量化分析和研究,通过可视化关键词的地理分布和构建的关键词网络发现,社团内部地区间的政策相似性主要并不取决于权重较大的关键词,而是由更多较小权重关键词共同决定的。文章还利用显性比较优势(RCA)进一步量化了各地的政策关键词的显性差异,得出各省、自治区、直辖市在政策关注上具有不同侧重的结论。更多还原

【Abstract】 “The Belt and Road” initiative has played a positive role in the development and improvement of the world economy and our people’s livelihood,since the implementation of “the Belt and Road”, many relevant provinces,autonomous regions and municipalities in China have actively deployed their own characteristics and issued a series of local “Belt and Road” related policies. Based on the keyword term frequency-inverse document frequency(TF-IDF),the article conducts a quantitative analysis and research on the policy texts related to “the Belt and Road” issued by the provinces,autonomous regions,and municipalities along “the Belt and Road” in China from 2014 to 2020,through visualization The geographical distribution of keywords and the constructed keyword network found that the policy similarity between regions within the community is not mainly determined by keywords with larger weights,but by more keywords with smaller weights. The article also uses revealed comparative advantage(RCA)to further quantify the significant differences in policy keywords in various regions,and draws the conclusion that provinces,autonomous regions,and municipalities have different focus on policy concerns.更多还原
