Your question is not very clear. Perhaps, you might care to be more precise?
What aspects of social entrepreneurship (SE) are you trying to ascertain, and then perhaps measure? Ascertaining is much easier than measuring, in my view.
I have so many questions churning in my mind. Are you interested to know?:
What prompts someone in the direction of social entrepreneurship?
How social entrepreneurship is accepted in one or more countries?
Who benefits from SE?
How many social entrepreneurs are there in your country?
Which part of society throws up the more SE persons?
Are there differences between the genders in embracing SE?
Does religion influence SE in various countries?
What are the educational antecedents of SE folk?
How many SE’s are very profitable, break-even or are making losses?
Are the support organizations for SE?
What is the role of government in promoting SE?
What percentage of the economy is based on SE? Etc.
I can think of many more but I hope the above helps.
You may refer to the article written by Vasudha Vasakarla (2008), A Study on Social Entrepreneurship and the Characteristics of Social Entrepreneurs. A tested questionnaire inside. Hope this could help. Regards, Cheah
well. the researcher might be actually trying to ask
How can we measure the outcome of SE activities? rather the social impact alternatively. It would give you a fair idea to start with by considering
which carries more social impact- feeding hungry or providing shelter to homeless? Indeed, social enterprises are subjected to a tension-fraught situation while deciding the optimum trade-off between social impact & economic outcome. There are debates going on to develop indices for SI measurement. You can refer to the sources added by other answers above.
further, you can attempt to narrow down your focus to delineate various dimensions of SE in your region to scale them in the form of a questionnaire..
Let me take advantage of this question to ask another question. The researchers can make a good discussion here.
What is the difference between social needs and opportunity? In my last question in researchgate, I didn´t have the book edited by Mair et al., and with the chapter titled: Navigating Social and Institutional Barriers to Markets: How social Entrepreneurs Identify and Evaluate Opportunities. (Author: Jeffrey Robinson).
Also I would welcome a good discussion on social entrepreneur failure (as it exist for non profit organization). If we are able to have good evidence on this, are social community based venture the good alternative to face market failure and government failure?
