Information carrier technology and growth
构建了一个包含信息载体技术的内生增长模型，指出知识存储损失和低通信效率会阻碍创新，并揭示了信息载体技术与人口增长率在决定人均产出增长中的替代关系。
Abstract This paper develops an endogenous growth model that incorporates information carrier technology, highlighting that knowledge loss during storage and low communication efficiency hinder innovation. The model identifies a turning point: prior to it, economic stagnation prevails with unchanging production technology; afterward, research and development activity drives technological progress and economic growth. On the asymptotic balanced growth path, the growth rates of information carrier technology and population act as substitutes in determining the growth rate of per capita output and the fraction of labor allocated to research and development. This model offers novel insights into unified growth theory and the mechanisms underpinning the digital economy.
