Analysis on economic efficiency of final demand.

This paper finds that, value added induced by per unit of final demand has decreased in China from 2002 to 2007, by employing non-competitive input-output model capturing processing trade. To explore the reason why it decreased, the paper proposes a modified structural decomposition analysis (SDA) method, considering the characteristic of multi-regional input-output table. By using this method, one not only can decompose the technology coefficients into substitution effect and fabrication effect, but also can evaluate the contribution of each region to the change of dependent variables. The results show that decreasing value-added ratio and change of final demand structure of domestic enterprises' products are the main causes of the decrease. Meanwhile, substitution of foreign invested enterprises' products to imports has inhibited this decline effectively. [ABSTRACT FROM AUTHOR]
