After reviewing the application of ICT in economic activities in LAC，the author characterizes the region’s ICT development from the aspects of basis and environment，demand and supply，trade and investment. While the increasing number of mobile services，internet and broad band users is pushing the demand curve further upward，the so called late starter’s bonus brought about by ICT redeployment of industrialized countries around the globe to LAC countries is driving the supply curve to meet the demand. However，despite of fast growing trade and investment in IT products，LAC has to catch up with other emerging economies in Asia whose ICT took off simultaneously with LAC but have reported faster growth rate and got larger market share than LAC. LAC’s efficiency oriented and market based ICT industries are dominated by foreign capital，certain risks remain to be weathered. The author concludes with various pubic policy proposals on development strategy，regulatory framework，investment and financing institution and human capital.
