Abstract: Based on the data of multiregional IOT in China’s eight regions,this paper first calculates the industrial forward and backward effect,and describes the outline of regional industry linkage in our country.Then,by using the Miller-Round model,the paper studies the spillover effect of regional economies in China.The result shows that,the regional economic linkage and spillover effect is still weak on the whole.The economical linkage among the coastal regions is relatively strong,and the spillover effect there is absorbed internally;economy in central China has a close linkage with that in both coastal regions and western regions,and it obtains a most spillover effect;economical linkage among the western regions is weak and it has a  strong spillover effect to other regions and a weak one from other regions,and economy there largely depends on coastal products;in the north-east regions,the economy is relatively close and the spillover effect to other regions and from other regions are both very weak.

Key words: multiregional IOT, regional industry linkage, spillover effect, empirical study
