Sustainable entrepreneurship contributes to solving social and environmental problems through the means of successful for‐profit businesses. This paper contributes to understanding how sustainable entrepreneurship is implemented by exploring an emerging new form of business, ‘B Corps’, that employs market tactics to address social and environmental issues. Through interviewing 14 B Corps, the exploratory research study found that B Corps treat profit as a means to achieve positive societal ends, they regard the B Corp model as a tool for change, the B Corp model provides a common collective identity for internal and external validation, they are focused on societal impact rather than maximizing profits and they attempt to legitimate this form of sustainable entrepreneurship by influencing the business community and government officials.

An upswing in labor costs and currency appreciation during the 1980s caused Asian countries and economic entities such as Hong Kong, Japan, and Taiwan to search for new manufacturing sites to obtain lower manufacturing costs. China, with its huge, rapidly growing market, was one of the main options for these Asian economic dynamos. How to find an appropriate method to evaluate an optimum place for a factory setup in China is essential to an enterprise. Analytical hierarchy processing (AHP) is a method to solve complex multicriteria decision problems. However, to make decisions based only on AHP results is not sufficiently reliable, especially when the results are too close to be precisely determined. To strengthen AHP analysis, we propose a “hybrid AHP” method. This method computes an error band (EB) of final AHP scores using its 95% Confidence Interval to estimate AHP score error and calculates EB combined with a “bootstrap” to mitigate expert pectoral bias. Based on our methods, our decision rule is “maximized AHP score and minimized EB.” To verify our methods, we took Taiwanese electronic assembly manufacturers selecting manufacturing sites in China as a case study. Our research found that Eastern China has a relatively higher consensus of preference for establishing their manufacturing sites. 相似文献

This paper examines freelancer cooperatives that have recently emerged in South Korea. In particular, it investigates the reasons why freelancers have established cooperatives and what conditions are required for freelancer cooperatives to increase their work. A review of the extant literature on the manner in which freelancers have to organize, as well as case studies regarding freelancer cooperatives, shows that freelancer cooperatives have emerged in order to reduce members' job uncertainty and to reduce time variance of projects assigned to a freelancer. Based on an analysis of freelancers’ organizational characteristics relative to entrepreneur cooperatives and worker cooperatives, we propose that the freelancer cooperatives are a hybrid between entrepreneur cooperatives and worker cooperatives. This paper also proposes the conditions required for development of freelancer cooperatives and suggests how those are distinguished from traditional entrepreneur cooperatives. 相似文献
