The history of modern economic development suggests that urbanization through migration is a result of industrialization. Despite different political, economic and technological conditions in today's developing countries, many studies have found that the patterns of urbanization in these countries are similar to those seen in today's industrialized countries at earlier stages of their development. China, as suggested by its rapid, post-reform urbanization through migration, is not an exception. Nevertheless, China's post-reform experience contrasted sharply with its slow and even stagnated urban population growth in the 1960s and 1970s, when it sought its industrialization goal under a central planning system. Perhaps because of its uniqueness of size and development experience, China's urbanization and rural to urban migration have remained a topic of great interest.
