An Analysis of the Three Turning Points in the "S-Shape"Rule of Steel and Cement Demand

This paper analyzes three key turning points on per capita steel and cement consumption S-shaped track, discusses the impacting factors and internal mechanism of the changing rule of the consumption intensity and per capita consumption amount, and illustrates an inverted-U track for the steel consumption intensity in the second industrial departments. Based on an analysis of economic structure changing tendency both in China and abroad, this paper concludes that GDP proportion in the second industry has reached the summit; it also predicts the peak value that the steel and cement consumption intensity will arrive at as well as the arrival time.
