The material flow theory and methodology have been applied to analyze quantitative characteristics of the total material requirement(TMR),the material intensity and the material productivity in the Chinese economic system during 1989 and 1996.

Expounds that culture industry promotes the development of material productivity,as well as spiritual productivity,and culture industry s promotion for productivity is comprehensive.

While Marx refutes so-called technology determinism,he regards material productivity as the ultimate system transition momentum.
