Recommendation to consider the crucial impacts of trends in smaller household size on sustainable development goals

The Rio Declaration, Agenda 21, the Johannesburg Plan of Implementation on sustainable consumption and production, and the Rio+20 Declaration have consistently emphasized the essentiality of promoting sustainable patterns of consumption and production to realize objectives of and requirements for sustainable development. To support these goals, this brief makes a recommendation to consider the crucial impacts of trends in smaller household size.

摘要　
资源环境绩效水平是衡量区域可持续发展能力的重要方面，其主要受到区域经济发展水平、技术水平、人口发展状况、 经济结构等诸多因素的影响。本文运用1990-2009年全球39个主要国家的资源利用指标、污染物排放指标及人口发展各分项 指标的数据，在构建综合评价模型评估各国资源环境综合绩效水平的基础上，采用经济计量模型模拟人口数量、人口质量、 人口结构及人口分布对各国资源环境绩效变动的影响机制，研究表明：①发达国家的资源环境绩效普遍高于发展中国家，且 在1990-2009年的时间序列上，国家间资源环境综合绩效变动呈现趋同趋势。②人均GDP和服务业所占比重对各国资源环境绩 效变动的影响均为正，且对发展中国家的影响要高于发达国家。③人类发展指数（HDI）和城镇化率对发达国家资源环境绩 效变动分别具有正向和负向影响，而HDI和总和生育率对发展中国家资源环境绩效变动则分别具有负向和正向影响。中国作 为发展中国家，未来宜着重从控制人口适度增长、提升人口素质、调整人口结构、改善人口城乡分布等方面入手改善资源环 境绩效。
