China's information and communication technology in geographic perspective

s Two economic geographers analyze the unprecedented growth of China's information and communication technology (ICT) industry over the past decade (2000-2010)-an industry increasingly important as a new engine powering exports and providing infrastructure and services critical to sustaining economic growth. Using agglomeration and inequality indices including the Herfindahl and the Gini, the authors show that the geographic concentration of ICT activities has decreased over time, in tandem with a decline in their regional inequality; however, a new ICT development index (IDI) designed for this study reveals a significant and persistent gap in ICT development between the country's advancing and lagging provinces. The paper also explores a range of factors contributing to "leapfrog" ICT growth in some provinces, as well as the challenges likely to be faced by the industry in the future.
