论文摘要
反对派经常批评从一个选举制度转换为另一个选举制度,并被视为执政党继续执政的一种手段。特别是,当新的选举制度是一个平行投票(或单个成员的地区)时,通常怀疑该执政党以将国家划分为选举地区的有偏见的方式,这样基于先验知识,它有更多机会在最大可能的地区赢得。在本文中,我们提出了一种新方法,以确定在平行投票系统下的特定政党是否从给定的区域地图中受益。作为我们方法论的一部分,我们制定并解决了一些烦恼的问题。我们展示了我们在2019年摩尔多瓦议会选举中的应用。我们的结果表明,与先前研究的论点相反,没有明确的证据认为这些选举中使用的区域图是不公平的。
Switching from one electoral system to another one is frequently criticized by the opposition and is viewed as a means for the ruling party to stay in power. In particular, when the new electoral system is a parallel voting (or a single-member district) system, the ruling party is usually suspected of a biased way of partitioning the state into electoral districts such that based on a priori knowledge it has more chances to win in a maximum possible number of districts. In this paper, we propose a new methodology for deciding whether a particular party benefits from a given districting map under a parallel voting system. As a part of our methodology, we formulate and solve several gerrymandering problems. We showcased the application of our approach to the Moldovan parliamentary elections of 2019. Our results suggest that contrary to the arguments of previous studies, there is no clear evidence to consider that the districting map used in those elections was unfair.
