Why is internationalisation of concern to SE?

There are various definitions of internationalisation, for example, Sommer (2010) states that “the internationalisation process involves the geographical expansion of economic activities across border”. Tukamushaba et al (2011) defines international social entrepreneurship as the “process of creatively discovering and exploiting social entrepreneurial opportunities overseas with the application of business expertise and market-based skills…with the pivotal objective of creating societal value rather than shareholder wealth in the overseas territories where the enterprise functions.”
