PURPOSE AND METHODS
The aim of this study was to investigate, with multiple regression analyses, the effect of selected characteristics on the rate of decrease of suicide rates in 21 OECD (Organisation for Economic Co-operation and Development) nations over the period 1990-2010, with initial levels of suicide rates taken into account.
RESULTS
The rate of decrease seems mainly (83%) to be determined by the initial suicide rates in 1990. In nations with relatively high initial rates, the rates decreased faster. The suicide rates also converged.
CONCLUSION
The study indicates that beta convergence alone explained most of the cross-national variations.
目的与方法
本研究旨在通过多元回归分析，考察在将1990年自杀率初始水平纳入考量的情况下，特定特征对1990 - 2010年期间21个经合组织（经济合作与发展组织）国家自杀率下降速度的影响。
结果
自杀率下降速度似乎主要（83%）由1990年的初始自杀率决定。在初始自杀率相对较高的国家，自杀率下降得更快。自杀率也趋于收敛。
结论
该研究表明，仅β收敛就解释了大部分跨国差异。
