Abstract

In this paper, the author takes Marxist dialectical materialism epistemology and the scientific development
concept of population and environment as the guiding thought, uses Marxist scientific abstract method, applies
Schumpeter’s “Theory of Stationary Circular Flow” and Xunhua Zhang’s “Theory of Productivity Layer”,
historically, logically, and systematically researches basic effects of productivity on the contradictory movement
of population and environment. It is stressed that one of severe challenges confronting China is that some basic
elements of productivity, such as population and environment, have already become the “strong restriction” to
improve life quality in China.
