在多元化和比例性之间:对投票转移系统的分析

Between plurality and proportionality: an analysis of vote transfer systems

László Csató

摘要:

本文考虑了一个选举制度的一般模式,结合以地区为基础的选举与补偿机制,以创造严格多数和纯粹的比例席位分配之间的任何结果。它包含投票转移,并允许应用三种不同的修正公式。对两党制的分析表明,占主导地位的政党在其预期席位份额和获得多数席位的机会之间存在权衡。还通过关注操纵的可能性来调查投票转移规则。该模型被应用于2014年匈牙利议会选举。假设的结果表明,选票转移规则不能单独评估,只能与选区席位的份额一起评估。如果适当选择后者,这三种机制在功能上可能是等同的。

英文摘要:

The paper considers a general model of electoral systems combining district-based elections with a compensatory mechanism in order to create any outcome between strictly majoritarian and purely proportional seat allocation. It contains vote transfer and allows for the application of three different correction formulas. Analysis in a two-party system shows that a trade-off exists for the dominant party between its expected seat share and its chance of obtaining majority. Vote transfer rules are also investigated by focusing on the possibility of manipulation. The model is applied to the 2014 Hungarian parliamentary election. Hypothetical results reveal that the vote transfer rule cannot be evaluated in itself, only together with the share of constituency seats. With an appropriate choice of the latter, the three mechanisms may be functionally equivalent.
