Final answer:
The basis of regionalism is the idea that unequal distribution of benefits of development on a regional basis can promote regionalism, but it is not the sole factor. Other factors such as cultural, historical, and political differences also play a role.
Step-by-step explanation:
The basis of regionalism is the idea that unequal distribution of benefits of development on a regional basis can promote regionalism. When certain regions of a country or area benefit more from development and economic growth than others, it can lead to a sense of regional identity and competition for resources and opportunities. Regionalism can be fueled by factors such as disparities in infrastructure, education, healthcare, and economic opportunities.
For example, if one region receives more investment in industries and infrastructure, it may become more prosperous and attract more businesses and opportunities. This unequal distribution of benefits can create resentment and a desire for greater autonomy or control over resources among the regions that feel left behind.
However, it is important to note that the basis of regionalism is not solely the unequal distribution of benefits, but it is one of the factors that can contribute to regionalism. Other factors such as cultural, historical, and political differences also play a role in shaping regional identities and aspirations.
