Final answer:
The example of a "push" factor in globalization is current home-country market saturation. This compels enterprises to globalize when their domestic market growth potential is maximized, forcing them to look for opportunities abroad.
Step-by-step explanation:
Among the options provided as a "push" factor in globalization, current home-country market saturation is a classic example. This occurs when a company's domestic market is fully exploited, and the growth opportunities become limited. To continue expanding, the enterprise must look beyond national borders, which acts as a 'push' towards global expansion.
'Push' factors in globalization are conditions in the home country that compel businesses to seek opportunities elsewhere. They can include various factors such as political unrest, poverty, natural disasters, high crime rates, and discrimination. The critical observation is that while enterprises are lured by the 'pull' of new markets, they are often propelled or 'pushed' when their existing markets no longer offer substantial growth.
When contrasting 'push' factors with 'pull' factors such as better labor supplies in other countries or favorable country-specific trade agreements, the distinct nature of these drivers becomes evident. 'Pull' factors are attractive elements in foreign markets that draw businesses in, while 'push' factors are those internal pressures that compel a business to seek international ventures.
