中国经济与社会发展统计数据库

《中国城市统计年鉴》是全面反映中国城市社会经济发展情况的资料性年刊。《中国城市统计年鉴2021》收录了2020年全国各级城市社会经济发展等方面的主要统计数据,数据来源于各城市的相关部门。 本年鉴内容共分四个部分:第一部分是全国城市行政区划,列有不同区域、不同级别的城市分布情况;第二、三部分分别是地级以上城市统计资料和县级城市统计资料,具体包括人口、资源环境、经济发展、科技创新、人民生活、公共服务、基础设施等方面的数据;第四部分是附录,为主要统计指标解释。需要说明的是,从1997年开始,地级以上城市和县级城市分别采用不同的统计制度,有些指标在两类城市之间不具有可比性,故本年鉴将地级以上城市和县级城市统计资料分为独立的两部分。此外,根据数据发布相关规定,经征求有关部门的意见,停止发布一些指标,如“专利申请数”“按产业、行业划分的城镇单位就业人员”等,暂停发布一些指标,如“户籍人口”“R&D内部经费支出”等,并对部分指标名称及指标解释进行了调整。 本年鉴所涉及的全国或全部城市统计资料,均未包括香港特别行政区、澳门特别行政区和台湾省。年鉴表中所列“全市”为城市的全部行政区域,包括城区、辖县、辖市;“市辖区”包括所有城区,不包括辖县和辖市。本年鉴各表中的空格表示该项统计指标数据不详或无该项数据。 本年鉴适用于各级政府管理部门、城市规划设计部门、城市社会经济研究机构、市政建设及房地产机构、各种中介服务及信息咨询机构等单位的工作者,也是大专院校师生、工商界人士、境外投资者以及关心中国城市发展的各界人士的重要参考资料。 本年鉴的编辑出版得到了国家统计局农村社会经济调查司、各省(区、市)统计局、各调查总队、各市统计局和调查队以及中国统计出版社的鼎力支持,在此表示衷心的感谢。 本年鉴编印工作量大,出版时间紧,难免有不当之处,诚恳欢迎广大读者批评指正。 China City Statistical Yearbook is an annual statistical publication.China City Statistical Yearbook 2021 reflects comprehensively the economic and social development of Cities in China.It covers the main socio-economic statistical data of cities at all levels for 2020,the data comes from the relevant departments of each city.
