This chapter turned its focus on critical elements such as access to capital, infrastructure, collaborative culture, and government policies in line with effective ecosystems. The chapter is based on case studies of the five entrepreneurial regions of Silicon Valley, Bangalore, Tel Aviv, Berlin, and Shenzhen, pointing out how each uses its unique strengths in building vivid entrepreneurial environments. A key place where the authors focus is on rising tendencies, such as models for working digitally, social entrepreneurship with a positive social impact, and the setting of technological advances to lead the way to future developments of these ecosystems. It also addresses bottlenecks other than financial constraints, which are regulatory barriers, which underline the need for strategies adapted to these constraints and collaboration. This insight that can be garnered from these dynamics could empower stakeholders to make entrepreneurial ecosystems that are much more effective at supporting sustainable innovation.
