Purpose: The article presents an analysis of the factors that lead to the repeated selection of specific suppliers and the effect of this recurrent selection on the pricing of public contracts. Design: A mix of quantitative and qualitative methods were used for the analysis. The logistic regression method was used to analyze the chances of obtaining repeated contracts. The classic ordinary least squares regression model was used to analyze the factor of contract pricing. The focus group method was used to explain the factors influencing the contracting authorities. Findings: The results show that prior procurement by a given contracting authority or work for the public sector in general has a statistically significant effect on the conclusion of contracts. The use of less transparent forms of input has a very strong impact. The non-transparent selection of suppliers, rather than the repetition of contracts, generally results in the overpricing of contracts. The IT sector is an exception. Originality: This research is original because it looks at the issue of the contracting authority in a wider context and through the view of the path dependency theory, which has not been previously applied to the public procurement environment. The focus on IT procurement, which, according to our research, has not been empirically investigated in this way, is also innovative.

反复选择供应商，因素和结果：捷克共和国

目的：本文分析了导致重复选择特定供应商的因素以及这种反复选择对公共合同定价的影响。设计：定量分析和定性分析相结合。逻辑回归方法用于分析获得重复合同的机会。使用经典的普通最小二乘回归模型来分析合同定价的因素。使用焦点小组方法来解释影响订约当局的因素。结果：结果显示，给定的订约当局或公共部门的工作通常在事先进行的采购中对签订合同具有统计学上的显着影响。使用不太透明的输入形式会产生很大的影响。供应商的不透明选择而不是合同的重复通常会导致合同定价过高。IT部门是一个例外。独创性：这项研究具有独创性，因为它在更广泛的背景下并通过路径依赖理论的视角研究了合同授权问题，而路径依赖理论是以前从未应用于公共采购环境的。根据我们的研究，尚未以这种方式进行实证研究的对IT采购的关注也是创新的。以前尚未应用于公共采购环境。根据我们的研究，尚未以这种方式进行实证研究的对IT采购的关注也是创新的。以前尚未应用于公共采购环境。根据我们的研究，尚未以这种方式进行实证研究的对IT采购的关注也是创新的。
