Geospatial information and technologies are widely used in South Africa, initially mostly with proprietary software but today, mature, open source alternatives such as QGIS are available. We wanted to find out if and why South African users accepted QGIS, globally the most widely used free and open source GIS. We adapted the extended unified theory of acceptance and use of technology model to test several hypotheses regarding the acceptance and use of QGIS in South Africa. 205 registered members of the Geo‐Information Society of South Africa completed a structured questionnaire. Results show that habit has the most significant influence on behavioural intention to use QGIS, followed by facilitating conditions, price value and social influence. Performance expectancy, effort expectancy, hedonic motivation and access to source code played no significant role. The findings show that adoption of QGIS in South Africa is not primarily influenced by benefits attributed to open source software, such as cost benefits, customizability, improved reliability, quality and security. The results are useful for developers of any GIS product and for choosing a GIS product for an organization, because they provide insight into the behavioural intentions of users.

接受开源地理空间软件：使用UTAUT2模型评估南非的QGIS

地理空间信息和技术在南非得到广泛使用，最初主要是使用专有软件，但如今，已经可以使用成熟的开放源代码替代方案，例如QGIS。我们想了解南非用户是否以及为什么接受QGIS，QGIS是全球使用最广泛的免费和开源GIS。我们采用了扩展的统一接受和使用技术模型的理论来检验关于南非QGIS接受和使用的几种假设。南非地理信息协会的205名注册成员完成了结构化问卷。结果表明，习惯对使用QGIS的行为意图影响最大，其次是便利条件，价格价值和社会影响力。预期效果，预期工作量，享乐动机和获取源代码的作用不明显。研究结果表明，在南非采用QGIS不受开源软件带来的好处的主要影响，例如成本收益，可定制性，提高的可靠性，质量和安全性。结果对于任何GIS产品的开发人员以及为组织选择GIS产品都是有用的，因为它们可以洞察用户的行为意图。
