This paper has copiled and updated Jiangsu Province s InputOutput table of threeregions and thirtysections in 00 and 987. The ey techniques include calculating IO coefficients by TFP, calculating Interregional coodity flows through gravitation odel, and updating IO coefficients by CE ethod which can iniize the inforation loss.
