This study investigates the effect of organizational support, perceived usefulness, and perceived availability of support schemes on public purchaser attitudes towards public procurement of innovations (PPI). Through a self-administered questionnaire, data were collected from a sample of public purchasers working in the Norwegian municipalities. The dataset was analysed through partial least squares structural equation modelling. The results show that organizational support is significantly associated with increased perceived usefulness of PPI, which in turn is positively associated with attitudes towards PPI. Contrary to our expectation, perceived availability of PPI support schemes is negatively associated with attitude towards PPI. Indeed, rather than strengthening the effect of public purchasers’ perceived usefulness of PPI on attitude it significantly weakens it. Although the results show that experience with PPI and the presence of a PPI strategy positively affect attitude towards PPI, their effects are not as strong as we expected. Further analysis showed that the most important factor in our model is the perceived usefulness of PPI, followed by organizational support. The study provides several managerial and policy implications. For instance, schemes for supporting PPI should be scaled up along with the dissemination of information about their mode of operation and the associated benefits.

这项研究调查了组织支持，感知的有用性和支持计划的感知可用性对公共购买者对创新公共购买（PPI）态度的影响。通过自我管理的调查表，从在挪威市政当局工作的公共购买者的样本中收集了数据。通过偏最小二乘结构方程建模对数据集进行了分析。结果表明，组织支持与PPI有用性的提高显着相关，而PPI的有用性又与对PPI的态度呈正相关。与我们的预期相反，对PPI支持计划的感知可用性与对PPI的态度负相关。的确，与其加强公共购买者对PPI有用性的态度影响，不然会大大削弱PPI的态度。尽管结果表明，使用PPI的经验和PPI策略的存在对PPI的态度产生了积极的影响，但其影响并不像我们预期的那样强烈。进一步的分析表明，我们模型中最重要的因素是PPI的有用性，其次是组织支持。该研究提供了一些管理和政策方面的含义。例如，应该扩大支持PPI的计划，并传播有关其运行方式和相关收益的信息。他们的影响没有我们预期的那么强。进一步的分析表明，我们模型中最重要的因素是PPI的有用性，其次是组织支持。该研究提供了一些管理和政策方面的含义。例如，应该扩大支持PPI的计划，并传播有关其运行方式和相关收益的信息。他们的影响没有我们预期的那么强。进一步的分析表明，我们模型中最重要的因素是PPI的有用性，其次是组织支持。该研究提供了一些管理和政策方面的含义。例如，应该扩大支持PPI的计划，并传播有关其运行方式和相关收益的信息。
