中文摘要：
  中国自杀率在1987—2008年间呈显著下降趋势。运用国家有关数据描述其间全国总自杀率及自杀率在性别、城乡人口中的分布，验证了全国自杀率逐年下降的显著性，并将自杀率与经济发展、流动人口等因素进行了相关分析与时间序列分析。中国的自杀率和经济水平的提高及流动人口的增长呈显著负相关关系，以此作为理论假设，用扭力情境的变化解释中国自杀率和经济发展关系，显示中国自杀率下降的主要原因在于很多原有冲突情境的弱化。
英文摘要：
  The period from 1987 to 2008 saw a substantial decrease in the suicide rate in China. This paper employs relevant national data to describe China’s total suicide rate and its gender and urbanrural distribution and proves that the yearly decrease is significant. It also conducts a relevance and time series analysis of the suicide rate and economic development and the migrant population. A significant negative correlation can be found between the suicide rate and economic development and the increase in the migrant population. With this as a theoretical hypothesis, this paper uses the change in the context of strain to explain the relationship between the suicide rate and economic development in China. It shows that the decrease in the suicide rate is largely attributable to the weakened conflict context.
