When we talk about Business Ethic, we not only refer to companies, but also add other parts to our discussion .
I found that Business Ethics are operated by several parts, including government, activists and so on.
I agree that companies should utilize competitive advantage to facilitate the implementation of social responsibilities. In the mean time, I think the purpose of social responsibilities cannot be simply defined as to obtain profits, even if it is associated with the resources and capabilities of the companies. In my opinion, Business Ethic is a kind of response to consumers whose demand stimulate the progress of the companies.
Also, companies need pressure from activists and media in order to find out the defection of their social responsibilities. But the government should supervise the media not to exaggerate certain issues, which will result in neglect of other important facts. To solve this problem, consumers should actively give companies feedback in order to prevent misunderstanding of exaggerated facts.
