The Middle Class of Business: Endurance as a Dependent Variable in Entrepreneurship
提出预测-控制空间理论框架，解释创业方法如何培育商业中产阶级（即规模不大但能持续发展的企业），并类比科学方法催生的中产阶级，说明这类企业如何为构建稳健社区和实现人类福祉提供非变动空间。
The prediction-control (PC) space offers a theoretical framework for the entrepreneurial method and shows how it can foster the development of a middle class of business, defined as ventures that grow and endure over time, but don’t necessarily grow very large in size. Analogous to the middle class in history fostered by the scientific method, the middle class of business is likely to provide spaces of non-churn and non-change requisite for the cocreation of robust communities and new ends worth achieving for human well-being. Such new ends are also likely to be crucial to tackling the problems of the 21st century and beyond.
