This paper attempts to analyze whether information technology can promote economic growth? Using mathematical modeling methods, this paper established an endogenous economic growth model containing information technology. The results show that advances in information technology are the engine of economic growth, and by improving the quality of capital goods, it reverses the trend of diminishing marginal product of capital goods and achieves transformation of economic growth pattern in the process of promoting economic growth. On the other hand, with the advances of information technology, information dissemination is more efficient. By reducing transaction costs and optimizing resource allocation, it would improve the total factor productivity.
