As Wichita seeks to reboot its spirit of entrepreneurship, we should make sure we do things that have a chance of working. The Kauffman Foundation has conducted research. One paper is Guidelines for Local and State Governments to Promote Entrepreneurship. In its introduction, it holds this:
In this paper, we begin with a critical overview of two of the most commonly used strategies to promote entrepreneurship: creating public venture funds and business incubators. We then explain that these strategies often neglect an essential principle: connectivity and learning by entrepreneurs. Next, we describe ways in which public venture funds and incubators can be reorganized based on the connectivity principle before concluding with several other recommendations for how cities and states can promote entrepreneurship and begin to see real results that transform economies and provide new opportunities to residents.
Kauffman also has many videos based on its research into this topic. An example is Myth-busting Entrepreneurship.
