      As the elderly care sector is characterized by several challenges, rethought and restructured organizations and institutions and thus innovation are necessary. This study investigated (1) what innovation in the elderly care sector means and (2) which factors determine the innovativeness of elderly care organizations. Our goal was to develop a framework to catch innovation and explain the capacity for innovation in the elderly care sector. Via case studies within five Flemish elderly care organizations, the applicability of the complex adaptive system (CAS) theory was examined. The results showed that organizations partially acted as CASs, but totally acting as CASs was restrained by top-down forces, procedures, and regulations.
    • The interaction between internal R&D and different types of external knowledge sourcing: An empirical study of Chinese innovative firms

      This paper investigates to what extent internal R&D efforts and different types of external knowledge sources jointly affect innovation performance of firms in emerging economies. Based on a survey about external knowledge sourcing activities of Chinese innovative firms, we categorize external knowledge sources into four groups: science-based partners, horizontal connections, value chain partners, and technology service providers. We find that both internal R&D activities and external knowledge sourcing have a positive effect on firms' innovation performance. Strong internal R&D capabilities also increase the effect of sourcing from value chain partners and horizontal connections, but we do not find support for complementarity between internal R&D and collaborations with universities and research labs. These findings jointly suggest that the mixture of different types of external knowledge partners in combination with internal R&D capabilities is crucial in understanding the role of open innovation in emerging economies.
    • Three Dimensional Model of Technology Innovation System Centered on Enterprises

      Although there is a high level of practitioner, policymaker, and scholar interest in social entrepreneurship, most research is based on case studies and success stories of successful social entrepreneurs in a single country. We develop a methodology to measure population-based social entrepreneurship activity (SEA) prevalence rates and test it in 49 countries. Our results provide insights into institutional and individual drivers of SEA. Using the Global Entrepreneurship Monitor (GEM) methodology of Total Entrepreneurial Activity (TEA), we find that countries with higher rates of traditional entrepreneurial activity also tend to have higher rates of social entrepreneurial activity. We develop a broad definition of social entrepreneurship and then explore types based on social mission, revenue model, and innovativeness.
