Cultural animation industry, with the characteristics of strong correlation effect and high valueadded, is at the highend of industrial chain. In order to quantitatively analyze forward and backward correlation degree and spreading effect of Chinese cultural animation industry, this paper integrates InputOutput Extending Tables of China into 124*124 sectors InputOutput Tables, and analyzes the proportion of cultural animation industry to other correlated industries of national economy by calculating consuming coefficient, distribution coefficient, intermediate demand rate, intermediate input rate, influence coefficient and sensitivity coefficient of cultural animation industry. The results show that cultural animation industry is a basicstyle industry of ultimate demand, has strong driving effect on other industries but the effect is not significant. 
