[目的/意义]从数据层面分析我国城市政府开放数据在主题视角和区域视角下的利用现状，探究开放数据关注程度与利用程度之间的线性关系，以提高我国政府开放数据的使用效率。[方法/过程]以哈尔滨、济南、上海、武汉、广州和贵阳6地为例，对开放数据的浏览率、下载率等多个指标进行统计比较分析、聚类分析和回归分析，揭示我国城市开放数据在主题与区域视角下的利用现状，并探讨浏览率与下载率之间的线性关系。[结果/结论]我国城市政府开放数据的利用具有以下特征：在整体上开放数据浏览率与下载率呈弱相关。在主题视角下，教育科技、民生服务、经济工商等与社会民生领域相关的主题利用程度高，其浏览率与下载率呈正相关；开放数据的整体特征与部分特征具有不一致性。在区域视角下，济南、上海的浏览率和下载率呈正相关，其中上海对开放数据的利用排名首位，济南则排在末位，贵阳开放数据浏览率与下载率都较高，但二者呈弱相关；开放数据整体特征与部分特征大体上具有一致性。
[Purpose/significance] This paper aims to analyze the use status of urban government open data in China from the perspective of subject and region, and explore the linear relationship between the degree of attention and utilization of open data, so as to improve the efficiency of the use of open data by our government.[Method/process] It selects six places such as Harbin, Jinan, Shanghai, Wuhan, Guangzhou and Guiyang as examples to conduct statistical comparative analysis, cluster analysis and regression analysis on multiple indicators such as browsing rate of the government open data to reveal the utilization status of China's urban open data under the thematic and regional perspectives, and to explore the linear relationship between browsing rate and download rate.[Result/conclusion] The use of open data by urban governments in China has the following characteristics:The overall open data browsing rate is weakly related to the download rate. From the perspective of the theme, educational technology, people's livelihood services, economic and industrial, and other topics related to the social and people's livelihood are highly utilized, and their browsing rate is positively correlated with the download rate; the overall characteristics of open data are inconsistent with some features. From a regional perspective, the browsing rate and download rate of Jinan and Shanghai are positively correlated. Among them, Shanghai ranks first in the use of open data, while Jinan ranks in the bottom. Guiyang's open data browsing rate and download rate are both high, but both are Weak correlation; the overall characteristics of open data and some features are generally consistent.
