The human immunodeficiency virus (HIV) infection rate for men who have sex with men (MSM) has rapidly increased in recent years in China and the migrant population accounts for a large proportion of this increase. The migration of MSM not only poses difficulties for government departments charged with treating the disease, but also increases the spread of HIV in geographical space, so it is important to understand the geographical distribution and migrant patterns of MSM. We searched the largest dating website in China to obtain open information from all users in the Chinese mainland from January 2006 to August 2017. For the analysis, the datasets were merged according to units of time and administrative regions. In total, 1,356,609 records were obtained for this study. The main users of the website were single males aged 18-35 years old. Most of the users were located in the large and mid-sized cities of East China. The distribution of MSM was strongly associated with the distribution of the development of service industry in geographical space. The main flow of MSM are mainly located inside the province as internal flow. For those MSM who prefer to migrate to other provinces, the Beijing-Tianjin-Hebei area, the Yangtze River Delta, the Pearl River Delta, and Sichuan and Chongqing area were their primary destinations. The interprovincial migration behavior of MSM was closely related to an increased average income. MSM prefer to migrate to cities with developed economies and open cultures. It is important to strengthen the management of migrant MSM and increase their basic understanding of HIV.
中国近年来男男性行为者（MSM）中的人类免疫缺陷病毒（HIV）感染率迅速上升，流动人口在这一增长中占很大比例。MSM 的迁移不仅给负责治疗疾病的政府部门带来困难，而且增加了 HIV 在地理空间中的传播，因此了解 MSM 的地理分布和迁移模式非常重要。我们在中国最大的交友网站上搜索，从 2006 年 1 月到 2017 年 8 月获取了中国大陆所有用户的公开信息。在分析中，根据时间单位和行政区域合并了数据集。总共有 1356609 条记录用于这项研究。该网站的主要用户是年龄在 18-35 岁的单身男性。大多数用户都位于华东地区的大城市和中型城市。MSM 的分布与地理空间中服务业发展的分布密切相关。MSM 的主要流动方向是省内流动。对于那些喜欢迁移到其他省份的 MSM，京津冀地区、长三角地区、珠三角地区和川渝地区是他们的主要目的地。MSM 的省际迁移行为与平均收入的增加密切相关。MSM 更喜欢迁移到经济发达、文化开放的城市。加强对流动人口 MSM 的管理，增加他们对 HIV 的基本认识非常重要。
