The journal’s name is “Social entrepreneurship and complexity models” from chapter four of the book “Complexity Science & Social entrepreneurship”. This paper talks about the relationship between social entrepreneurship and complexity models. Entrepreneurship has the power to transform society to a much greater degree than is commonly believed. In addition, leaders and managers play different roles in organizations. From my point of view, I totally agree with all points in the paper. Social Entrepreneurship is a complex model in economic and social entrepreneurship always involved different types of complex models. The paper can separate two parts---firstly, this paper initially presents a systems informed definition of social entrepreneurship with an emphasis on the characteristics of social entrepreneurial ventures. In the second part, it outlines different types of complex models related to social enterprise and then talks about general implications of complexity for leadership of social enterprise.

1. The definition of social entrepreneurship and characteristics of social entrepreneurial ventures
