Replication Data for: Why we should use the Gini coefficient to assess punctuated equilibrium theory

Punctuated Equilibrium Theory (PET) posits that policy-making is generally characterized by long-periods of stability that are interruped by short periods of fundamental policy change. The literature converged on the measure of kurtosis and L-kurtosis to assess these change patterns. In this letter, we critically discuss these measures and propose the Gini-coefficient as a (1) comparable, but (2) more intuitive, and (3) more precise measure of ‘punctuated’ change patterns.间断均衡理论（Punctuated Equilibrium Theory, PET）认为，政策制定整体呈现长期稳定的状态，其间会被短暂的根本性政策变革所打断。学界普遍采用峰度（kurtosis）与L-峰度（L-kurtosis）来评估这类变革模式。在本学术短讯中，我们对上述两类测度方法展开批判性探讨，并提出将基尼系数（Gini-coefficient）作为兼具（1）可比较性、（2）更强直观性与（3）更高精准性的“间断式”变革模式测度指标。
