RATIONALEDemographic change has created significant societal challenges in Sweden, such as aging population and immigrant integration. The global pandemic exacerbates the situation. Sweden is among the countries with highest level of life expectancy in the world (UN, 2015; WHO, 2016) and loneliness of senior people has long been a social problem (Toube 2013). Due to the pandemic restrictions, senior loneliness has greatly increased according to a report of the Swedish Public Health Agency, 2021. Social segregation is another societal challenge in Sweden particularly after the 2015 refugee crisis. Statistics shows that immigrants are disproportionately exposed to the risk of severe Covid complications and death. The refugees are among the most severely impacted due to higher proportion of overweight, obesity, smoker, and poorer access to health care (Magrio et al. 2020, Zdravkovic et al. 2020.The enormous scale and scope of these societal challenges make it impossible to offer effective solutions solely by government nor by conventional ways of social services. So far, academic, and political discourses have primarily emphasized state-led and market-driven solutions, or technological fixes. Lately, however, the attention has been turned towards social innovation which entails new concepts, approaches, and solutions for sustainability. The mechanisms of social innovation are the exchange of ideas, shifting of roles, blending market and public principles, and co-creation of knowledge among public and private sectors as well as NGOs and individual citizens (Phills et al. 2008, Westley et al, 2017 which relies on the triple helix (TH) partnership and beyond.Housing is one of the most important social determinants of health, social justice, and social equity. Housing company's role in sustainable urban development is non-substitutable. However, most of the literature related to real estate and innovation is about technological innovation targeting environmental issues such as energy consumption and building performance (Pauli et al. 2020). Social innovation in housing, particularly those through TH partnership, remain ignored in research.
RESEARCH QUESTIONThis paper studies the process of knowledge co-creation through TH partnership and beyond in two social innovation projects in a municipality in Sweden. We try to answer the questions as follows:• What are the mechanisms of knowledge co-creation for social innovation?• What are the different actors' roles in the process of knowledge co-creation?The Determinants of Office Yields in European Cities.
