本文为测量沪宁高铁沿线主要城市2005—2013年旅游产业的集聚水平选取赫芬达尔指数和空间基尼系数,分析研究沪宁高铁开通前后沿线城市旅游产业集聚的变化情况以及相关行业产生的影响的差异化状况。研究发现:沿线城市旅游产业的集聚水平在2010年沪宁高铁开通后呈显著提升的态势;但沪宁高铁沿线城市旅游行业集聚水平所受影响差异明显;沪宁高铁沿线城市旅游产业的集聚程度在国内相对较高,增长速度较快;同时沪宁高铁沿线城市旅游产业的空间集聚程度较为不均衡。 In order to measure the concentration level of tourism industry in major cities along the Shanghai-Nanjing high-speed railway from 2005 to 2013, the Herfindahl index and space Gini coefficient were selected to analyze the changes of urban tourism industry agglomeration along the line before and after the opening of the Shanghai-Nanjing High Speed ​​Rail and the impact of related industries Differentiated status. It is found that the level of agglomeration of tourism industry along the line increased significantly after the opening of Shanghai-Nanjing high-speed railway in 2010; however, the concentration of urban tourism industry along the Shanghai-Nanjing high-speed railway was significantly affected by differences in agglomeration levels; the concentration of urban tourism industry along the Shanghai-Nanjing high- Which is relatively high in China with rapid growth; meanwhile, the spatial agglomeration degree of urban tourism industry along the Shanghai-Nanjing high-speed railway is relatively uneven.
