Scholarly evidence of transparency's beneficial effects on trust and perceptions of corruption remains debated and confined to the study of public administration. We contribute to this debate by extending the study of its effects to transparency legislation concerning members of parliament (MPs), political parties, and business interest groups. In an online experiment conducted in Ireland with 1373 citizens, we find that transparency in political donations improves trust in political parties, while asset declaration for conflict of interest prevention reduces perceptions of corruption toward MPs. However, transparency in lobbying is found to have no impact on attitudes toward business interest groups. This supports the common expectation that transparency improves political trust and reduces perceptions of corruption, but also confirms its complex effects. The study improves our understanding of transparency beyond open government providing an evaluation of different regulatory policies aimed at making the activities of parties, MPs, and lobby groups transparent.

透明度监管对政治信任和腐败感知的影响：调查实验的证据

关于透明度对信任和腐败认知的有益影响的学术证据仍然存在争议，并且仅限于公共行政研究。我们通过将其影响研究扩展到涉及议会成员 (MP)、政党和商业利益集团的透明度立法，为这场辩论做出贡献。在爱尔兰对 1373 名公民进行的在线实验中，我们发现政治捐款的透明度提高了对政党的信任，而用于预防利益冲突的资产申报则减少了议员对腐败的看法。然而，游说的透明度并没有影响人们对商业利益团体的态度。这支持了人们的普遍期望，即透明度可以提高政治信任并减少对腐败的看法，但也证实了其复杂的影响。该研究提高了我们对开放政府之外的透明度的理解，对旨在使政党、议员和游说团体的活动透明化的不同监管政策进行了评估。
