中文摘要：

由于开源软件开发方式与传统的软件工程方法存在显著差异,为了加入开源社区,商业组织必须要对自身原有的软件开发方式、业务模式等做出调整.在这种情况下,一个亟待解决的问题是商业组织应当采取怎样的参与模式才能有效融入开源社区.为此,进行3个方面的研究：采用雪球采样方法对OpenStack相关的文本数据进行收集,为定性分析提供数据基础;借鉴扎根理论,通过对所收集数据的过滤和归纳,总结出不同商业组织参与OpenStack的模式;在此基础上提炼出4种更具一般性的参与模式,为商业组织参与开源项目提供经验参考与决策支持.

英文摘要：

There are a lot of differences between the open source software development approaches and the traditional software engineering methods. If commercial organizations want to join the open source community, they must make some adjustments in their own original software development approach and business model. In this case, an urgent problem needs to be solved immediately is what involvement model the commercial organizations should adopt to achieve their goals of joining the open source community. This paper first collects project text data from the Internet as a basis for qualitative analysis using snowball-sampling collection mechanisms. Then, based on the classical grounded theory, it summarizes different commercial organizations＇ involvement model in open source projects through filtering and analyzing these data. Finally, the study extracts four kinds of general involvement model which can provide decision supports and experience references to those commercial organizations who want to join the open source software proiects.
