本文从复杂系统的社会动力学和社会物理学的角度阐明了政府支持率时间序列的统计力学性质。我们发现，支持率波动的分布表现出指数独立的国家。引入以指数分布定义的“挥发温度”，可以一般地理解，高、低温国家分别对应于议会内阁制和总统制。研究还发现，许多国家政府的支持率时间序列呈现出自仿射分形特征，且存在正相关或负相关。满意度时间序列是少数负相关现象的典型代表。(C)2015 Elsevier B.V.版权所有。
We elucidate the statistical mechanical properties of the approval rating time series of several governments from the social dynamics of complex systems and sociophysics points of view. We find that the distribution of approval rating volatility shows exponential independently on nations. Introducing "volatility temperature" defined with the exponential distribution, it could be understood generally that high and low temperature nations correspond to parliamentary cabinet and presidential systems, respectively. We also find that approval rating time series of many governments shows self-affine fractality with negative or positive correlation. Approval rating time series is typical one of few negative correlation phenomena. (C) 2015 Elsevier B.V. All rights reserved.
