The study investigates intellectual capital management (ICM) and economic development in a quasi-information society such as Nigeria: a macro perspective. The study adopts the correlational research and secondary data were used. From a macro perspective, data used for the human capital development are literacy level, human development index, and Gini coefficient, among others. Structural capital include telecom rate to GDP, mobile cellular subscriptions, mobile cellular subscriptions (per 100 people), and Internet penetration and use rate. Also, economic development as the dependent variable represents the GDP. Data within the periods of 2005 and 2015 were used, and regression analysis and ANOVA were used to explain the relationships between variables of interest of the study. The findings showed that there was no significant increase in the development of the Nigeria economy in the periods of 2005-2015 and the ICM of the nation does not have significant impetus on the economy. The study recommends that for the level of development to increase in Nigeria, governments and policy makers should concentrate and seek strategies to provide policies that would enhance the IC of the nation such as the level of literacy, innovative research, and development, among others.
