    There are many examples of countries that have converged with developed countries which validate the catch-up theory. [5] Based on case studies on Japan, Mexico and other countries, Nakaoka studied social capabilities for industrialization and clarified the features of human and social attitudes in the catching-up process of Japan in the Meiji period (1868-1912).
