Interrelations between environmental pollution, economic growth and population distribution in gradient economic zones in China

Based on Schumpeter´s “Theory of Stationary Circular Flow” and Xunhua Zhang´s “Theory of Productivity Layer”, the author researches basic effects of productivity on the contradictory movement of population and environment. Then, this article makes an EKC analysis in the industrial effluent, industrial waste water and industrial sulfur dioxide in the three major economic zones in China. Thirdly, by referring to the tool of index distribution quotient and comprehensively observing the industrial structure pattern of population, this article finds out that an obvious economic gradient zone feature exists in the three major economic zones. This not only provides thinking for exploration of specific tactics in gradually promoting gradient transfer of population industrial structure among the three major economic zones, but offers theoretical foundation to realize the relatively balanced “win-win” between economic layout and environment development.
