The funding process is increasingly under scrutiny in order to ensure the effectiveness of research investments. This paper contributes to improve our understanding of the effects of funding on research performance through the analysis of the scientific publications of Spain-based researchers in seven disciplines during a five-year period. Funding data are extracted from the “Funding acknowledgment” field of the WoS database. Firstly, funded research is compared to the non-funded one regarding impact and collaboration through bivariate analyses. Funded research is published in more prestigious journals, attains higher citation rates and is developed in teams of greater size in all disciplines, but only in a few of them is associated to greater extra-mural collaboration. Secondly, a logistic regression model is used to explore whether funding contributes to explain the likelihood of papers to attain citation rates above world average controlling for other variables such as prestige of publication journal and collaboration. Thirdly, funding shows direct and indirect effects on the citation rate of papers. Indirect effects are mediated through the publication of more complete papers, in more prestigious journals and with more extensive collaboration, although the presence and magnitude of these effects vary by discipline. The results are discussed in the context of their interest for research policy.

为了确保研究投资的有效性，越来越多的资助过程受到审查。本文通过对五年中七个学科的西班牙研究人员的科学出版物进行分析，有助于增进我们对资金对研究绩效的影响的理解。资金数据是从WoS数据库的“资金确认”字段中提取的。首先，通过双变量分析将资助研究与非资助研究的影响和合作进行比较。资助的研究发表在更多的著名杂志上，获得更高的引用率，并且在所有学科的团队中规模更大，但只有少数几个与更大的壁外协作相关。其次，逻辑回归模型用于研究资金是否有助于解释论文获得高于世界平均水平的引文率的可能性，从而控制其他变量，例如出版期刊和合作的声望。第三，资金对论文的引用率具有直接和间接的影响。间接影响是通过发表更完整的论文，在更有名望的期刊和更广泛的合作中实现的，尽管这些影响的存在和程度因学科而异。在研究兴趣的背景下讨论了结果。资金对论文的引用率具有直接和间接的影响。间接影响是通过发表更完整的论文，在更有名望的期刊和更广泛的合作中实现的，尽管这些影响的存在和程度因学科而异。在研究兴趣的背景下讨论了结果。资金对论文的引用率具有直接和间接的影响。间接影响是通过发表更完整的论文，在更有名望的期刊和更广泛的合作中实现的，尽管这些影响的存在和程度因学科而异。在研究兴趣的背景下讨论了结果。
