Abstract

The convergence of the information and communication technology (ICT) industry is ubiquitous phenomena, which can be classified from the supply/demand side or complementary/substitute relation. According to the classification, the paper measures the convergence of China's ICT sectors based on its 2002 input-output (IO) table, including five manufacturing sectors and two service sectors. Then, using IO table cross-entropy updating technique, the paper investigates the convergence evolution of four ICT manufacturing sectors from 1997 to 2002. The research finds the following conclusions. In 2002, the supply side convergence of manufacturing sectors was higher than that of service sectors, while service sectors featured a higher degree of the demand side convergence. The year of 2002 witnessed high complementary convergence between some China's ICT manufacturing and service sectors. During the period from 1997 to 2002, the supply side convergence dominated the convergence of China's ICT industry, while the demand-side convergence experienced little structural change.
