Variables and operational definition.

The arguable claims of levels of trust in politics and business situations motivated this study, which investigates the degree of trust within micro, small, and medium categories of Hungarian Information and Communication Technology (ICT) companies. Different sizes of companies have varying interactions between internal members and their business partners. This study concentrated on exploring Hungarian ICT companies due to their significant role in supporting Industry 4.0. The study population are active Hungarian ICT companies. This research implemented random cluster selection related to the location of ICT firms. It exploited 100 samples, including micro, small, and medium-sized companies, and implemented discriminant analysis to examine the description and hypotheses. First, this study found that the level of trust in institutions within micro, small, and medium-sized companies varies significantly. The level of trust in institutions proliferates within corporations due to the capability of the formal institution to provide fair public services. This research additionally underlined that the performance of the Hungarian government would improve trust amongst the companies. Second, this study concluded that the level of interpersonal trust within three categories of companies was similar. A high level of interpersonal trust would expand internal engagement among the members of companies. Finally, the level of trust in business partners varied significantly within the distinct sizes of Hungarian ICT companies. A high level of trust in corporate associates improves business collaboration, reduces uncertainty, and supports long-term business connections. Levels of institutional trust and inter-organizational trust differed amongst different categories of companies. However, the level of interpersonal trust remained similar within companies of the various sizes.

针对政治与商业场景中信任水平的争议性论断，为本研究提供了核心动因。本研究聚焦匈牙利微型、小型及中型信息技术（Information and Communication Technology，ICT）企业内部的信任程度展开调研。不同规模的企业，其内部成员与商业伙伴间的互动模式存在显著差异。鉴于匈牙利ICT企业在支撑工业4.0（Industry 4.0）进程中发挥的关键作用，本研究选择其作为调研对象。本研究的研究总体为存续运营中的匈牙利ICT企业，采用与ICT企业区位相关的随机整群抽样方法开展样本选取，最终获取100份涵盖微型、小型及中型企业的有效样本，并通过判别分析对研究描述与研究假设进行检验。本研究主要得出三项结论：其一，微型、小型及中型企业内部对机构的信任水平存在显著差异；正式机构具备提供公平公共服务的能力，可有效提升企业内部的机构信任水平，同时匈牙利政府的履职表现也能提升企业间的信任水平。其二，三类企业内部的人际信任水平并无显著差异，较高的人际信任水平可增强企业内部成员的参与度。其三，匈牙利不同规模ICT企业对商业伙伴的信任水平存在显著差异；对企业伙伴的高信任水平可优化商业协作、降低运营不确定性，并助力构建长期商业合作关系。整体而言，不同类别企业的机构信任与组织间信任水平存在差异，但不同规模企业内部的人际信任水平仍保持一致。
