我们分析了人均国内生产总值(GDP)的跨国分布及其从 1970 年到 2009 年的演变。我们认为,峰值并不是衡量人均 GDP 跨国分布中明显收敛俱乐部/均衡的合适指标,因为在数据的非线性严格单调变换(例如对数变换)下,峰值的数量并不是不变的。相反,我们将分布建模为有限混合,并通过统计测试确定其成分数量。我们发现,20 世纪 90 年代中期,跨国分布中的组成部分数量从 3 个变为 2 个。
We analyze the cross‐national distribution of gross domestic product (GDP) per capita and its evolution from 1970 to 2009. We argue that peaks are not a suitable measure for distinct convergence clubs/equilibria in the cross‐country distribution of GDP per capita, because the number of peaks is not invariant under non‐linear strictly monotonic transformations of the data such as the logarithmic transformation. Instead, we model the distribution as a finite mixture, and determine its number of components via statistical testing. We find that the number of components in the cross‐country distribution changes from three to two in the mid 1990s.
