ABSTRACT
There are many possible definitions of internationalization, some referring to the whole economy of the home, or internationalizing, country, some referring to specific sectors of the economy, and some referring to MNEs themselves. Whatever the scope of the definition, there are many alternative measures of the extent of internationalization, including production, sales, assets and employment. This chapter emphasizes production as a measure, as far as possible, despite some ambiguities about its meaning.
