title: The economic law of population distribution and migration.
abstract: "The economic law of population distribution and migration has been studied chiefly based on the Chinese situation.  The distribution and development of productive forces decide the distribution and migration of population, and in turn, the latter influences the former.  The population distributions in three different stages of social development, namely agricultural, industrial and information society, are described.  A new concept in population economics is introduced, i.e. population economic density, which is different from the concept of population density.  The formula of population economic density is P(population)/R(resources).  Many kinds of migration are analysed, and it is believed that the main efficient cause of migration is economy."
